More About Baby Monitor

There are dozens of styles of baby monitors available for purchase at baby products stores. When you're buying a baby monitor, you should look for one that fits your lifestyle and the home in which it will be used. The following suggestions will help you find the perfect baby monitor so that you can keep a closer eye on your baby for safety and peace of mind.

Baby Monitor Range
If you only want to monitor your baby from a few rooms away, or in a small house, almost any baby monitor will do. If you have a large or multi-story home, or you'd like to be able to take the receiver outside to a large yard or detached garage, look for a baby monitor with a longer range, so you can be sure you'll hear baby from far away.

Interference
If you have close neighbors with children, keep in mind that other families may have baby monitors that use the same channels, meaning that you may hear what happens in other homes, and they may hear you. Cordless phones may also pick up baby monitor sounds. If interference is a concern for you, look for a baby monitor that has added security features or no-interference technology.
All types of baby monitor, like baby sound monitor, video baby monitor, toy baby monitor, wireless baby monitor, multi-camera baby monitor, multi-channel baby moniotr.

Monitoring Sounds, Sights and More
Basic baby monitors let you hear what's happening in baby's room. Modern baby monitors also let you watch baby on video, and even to monitor baby's breathing and movement. Video monitors are helpful, but you won't want to watch the screen constantly, so be sure the monitor also has good sound. Movement sensors add peace of mind, but the AAP warns that parents may gain a false sense of security from movement monitors. Checking your baby personally is still the safest option.

Multi-Room Monitoring
Most baby monitors have one transmitter for the nursery and one or two receivers that let parents listen to baby. If you want transmitters in more than one room, or for more than one child, there are fewer choices. Some parents buy two or more baby monitor systems to monitor different children, but with this option you must choose systems that don't interfere, or you'll only hear annoying electronics screeches. A few baby monitors today have multi-room monitoring options, though.

Baby Monitor Portability
The majority of baby monitor receivers today have at least a belt clip that allows parents to carry the receiver with them around the house. If you want to move the receiver around a lot, check the belt clip or attachment method to be sure it's sturdy enough to withstand daily use. Also check the power source and battery life. Will you need to plug it in constantly? Some new baby monitors have ultra-small receivers on a lanyard or belt-clip for great portability, too.

Spy camera pen 4gb is popular among the people in the areas as business, education, safety, mass media, tourism, medical, even ordinary life, and etc.

Some About Spy Camera Pen Recorder
There are many spy camera pens on the market – some color, some black and white and some audio. Certain cameras do all the above, others just take pictures or record sound. All of our 2g/4g/8g spy pen camcorders sold there are multi-function type.
Use one at home to keep tabs on your private belongings, or on vacation – see what the hotel staff are up to in your room.

Even sneak one in to a trade show – get secret pictures of new technology.

Video Spy Pen - You can slip it in to your pocket, then click the button for instant color pictures and audio recording. The picture quality is high, the audio is clear enough.

You can easily attach the receiver to a TV or VCR to record your surveillance footage.

The only issue is you need the receiver (you get this included) to be within 100 meters and in line of sight of the spy pen – this does limit your uses for using a video spy pen so unless highly important a combination of the still camera pen and the audio pen offer great mobility and detailed surveillance possibilities.

Digital Image Spy Pen - The pen is totally self sufficient and can be carried anywhere - perfect for on the move surveillance.

This digital camera spy pen looks totally normal and writes totally normal as well. No one will know that you're taking their picture. The 36 pictures it stores in its 2MB memory are good enough in quality for recording documents, files or regular images. The focus and exposure is all auto, and the battery life seems very long (they say 500 pictures but it seems more).

Audio Spy Pen Camera - The audio spy pen camera is another one suited for "on the move" surveillance (it’s worth considering to take both; a still image and an audio spy pen to cover all eventualities.

My favorite audio spy pen is digital, has 128 MB of memory, can record up to 8 hours of audio - it can be carried and used anywhere. You can disguise it as a key-ring with the parts included and it is internally rechargeable – no batteries to replace.

Lenovo IBM ThinkPad X60 Tablet

Lenovo's ThinkPad X60 is an ultra-light Tablet PC with a heavyweight punch. The X60 takes advantage of and positively upholds the excellent reputation of the IBM ThinkPad line of laptops. ThinkPads are slightly utilitarian in design, but this is part of their universal appeal. Even as an ultra-portable, the X60 may have enough sinewy power to give bulkier, high-spec laptops a tough run for the money.



Features and Design

The Lenovo X60 tablet PC, aka ThinkPad X60 Tablet, is billed as an ultra-portable 12" laptop that crams a lot of features into a relatively small package. The X60 is absolutely lightweight and travel-friendly at a reported 3.8lbs. Of course, this weight is sans-battery. When I placed the X60 on my digital scale, the weight was slightly higher than expected at 3.94lbs. With the 8-cell Lenovo IBM ThinkPad X60 Tablet battery attached (4-cell battery available as well) the weight of the X60 increased to 4.94lbs. This is still lighter than most competitive laptops.

Lenovo offers an optional expansion dock for the X60. This dock gives X60 users access to a 24/16/8/4/2.4X CD-RW/DVD drive, 4 USB 2.0 ports, VGA video out, an archaic serial port, parallel port, audio in/out, a secondary power adapter port, a fax/modem and a 10/100 LAN port. The expansion dock is ideal for execs and managers who have external monitors, keyboards and mice permanently set up at one or more work spaces. Moving the X60 between mobile/compact mode and docked/desktop mode is as easy as a single click in XP and releasing the undock lever on the expansion dock.

Without the "ThinkPad X6 Tablet UltraBase" expansion dock, the X60 is slightly less functional. It does not have an optical drive built-in, which means no CD or DVD drive. To use CDs or DVD on the go, one must have copied disk images to the hard drive with an included utility, or one must use an external USB CD/DVD drive. There are three USB 2.0 ports, a single 4-pin FireWire port, built-in SD/MMC card slot, dial-up modem port, infrared port, embedded WWAN, VGA video out, audio input and output jacks, and a much-appreciated PC Card slot for flash card readers, USB expansion ports, etc. Essentially, any expansion needs could be managed by way of PC cards or USB devices.

The 12" TFT screen is clean and bright. Surprisingly, the X60 doesn't take advantage of the highly popular widescreen format. It's odd using a near-square portable after being on wide-screens for several years. Additionally, the matte screen is limited to a 1024x768 resolution. The X60 doesn't have a dedicated graphics card - rather, it uses upwards of 128MB of system memory for video. Sadly, the X60 doesn't offer any DVI video out, even with the expansion dock. Finally, unlike many new laptops on the market, the X60 does not have an integrated webcam.

The keyboard measures just over 10" wide, which forces keys to be slightly smaller than on standard laptops, but near equal to that of other ultra-portables. The X60 however, superimposes a great number of Fn options on keys which makes it look a little hectic. Once the visual noise settles down, keyboard use is intuitive and fluid.

The internal hard drive (60GB to 120GB) is a 5400rpm SATA drive. If you want a 7200rpm drive for extra speed, Lenovo offers a 100GB SATA drive for an extra cost.

Like most IBM/Lenovo laptops, the X60 has a red mouse pointer nub smack in the middle of the keyboard instead of a trackpad below the keyboard. I'm sure there are thousands of people who prefer the nub. It's easy to get used to, but this techie thinks it's a misplaced oddity.

The X60 has a built-in biometric security device - a small fingerprint scanner located at the bottom right corner of the LCD screen. The scanner is about the size of a piece of macaroni, or the tip of a 6-pin USB plug. When the biometric security is enabled, it can be used for XP login, program/file/website access. This is an essential security feature where corporate competition and identity theft force people to be more protective of their data.

As for design, the X60 is pretty utilitarian. In a world of pretty MacBooks, Sony Vaios and Toshibas, the X60 looks Borg. It's a no frills, no pizzazz workhorse - albeit a tough, high powered, skilled workhorse that can run circles around competitive systems.

Amazing 4GB RAM Capacity

One of the most impressive and desirable aspects of the X60 is the fact that RAM can be upgraded as high as 4GB. That's right - 4 whole gigabytes of lightning fast PC2-5300 667MHz RAM. It's enough to make a geek break into a giddy sweat. Major kudos to Intel and Lenovo for such an awesome endowment.

Extended Your Laptop Battery Life 5 Tips

1. Turn the brightness level as low as you possibly. Laptops always come with the ability to select the brightness level, some even could modify CPU cooling performance, switch down to lowest level will enable you squeeze out two times longer battery life than the situation working in the highest level.

2. Shut down programs running automatic. Some of the programs we won't to use startup in backgroud when you start you OS, like QuickTime, Desktop Search. When expand your taskbar, you can see and shutdown them, but there are also some process invisible in most cases. They consume your laptop computer resourse and slowly, press "Ctrl" + "Alt" + "Del" to open your tasker manager and halt the process not necessary.

3. Unplug external devices. Normally device, your mouse, and the most power consume device -- Mobile hard disk, they drain down your laptop battery like IBM THINKPAD X SERIES battery for there get the power supply from the USB port in your laptop. Remove when you aren't using them, is goes without saying that this will save a lot of power.

4. Hibernate instead of suspend. Suspend mode make your save some power and instantly resume your laptop when you come back, but compare with the Hibernate mode, suspend laptop also running in lower power consumed situation, electricity exhaust is zero in hibernate mode for all your computer's state were saved before it shutdown. For the convenient reason, you'd better use the hibernate function when leave over 20 minutes.

Proper Use and Maintenance of Camcorder Lithium Batteries

Digital video camcorder have been great strides into the family, many ordinary families have a personal mini "Digital Imaging Workshop", can produce digital images CD-ROM belong to their own arbitrarily. However, in the use process of digital camcorders, we will find such a problem - the current digital camcorders are generally used rechargeable lithium-ion battery with a high price, the major manufacturer have "little words" in the products specifications about the proper use of lithium-ion battery . The usage many people get from a variety of channels are not very correctly, so many people' original battery is closer to "scrap" when get a not long battery life time, and had no choice but to spend lot of money to buy second battery, that adds much trouble.



In fact, although there are a wide range of different models batteries currently on the market , different manufacturers use different battery models, and sometimes will lead to consumers get no idea choose what to do, but the method in use is more or less the same. Today, we are on to explain the proper use of a digital camcorder lithium ion battery, and hope to be helpful to everyone.

When we buy a new digital camcorder, the first thing to do is charge the lithium batteries, battery internal management circuit charge the rechargeable lithium batteries is a complex process, it is necessary to ensure that lithium batteries' full performance, but also to ensure that rechargeable lithium batteries should not have charge too more, because if the the charge current is too large, or the charging time is too long, oxygen generated consumped too late, may result in hypertension, battery deformation , leakage and other undesirable phenomena, even cause a serious explosion or fire, so must be in accordance with the right method of charging.

Many friends consider the previous three times use of lithium batteries should be charging more than 16 hours, that can be fully activate the battery. in fact, it is only popular Ni-MH or Ni-Cd battery charging method not apply for lithium-ion batteries. Since such a battery with lithium polymer as its core have no memory effect, so only about three hours charger is entirely. On a general chargers sell with the camcorder have a display function, if the show it has completed charging, you can unplug power supply, do not have to wait such a long time!

In general, lithium batteries can be recharged 300-500 times, according to the different methods and frequency of use, may be your digital camcorder battery can be used a few years or only one year, so the routine maintenance is importance. According to IEC standards require, the battery should be store under the conditions temperature of 20 + -5 ℃, humidity of (65 - +20)% , to avoid placing in very hot space. Generally speaking, the higher the temperature of the battery storage the lower capacity of the remainder, and vice versa. So we had better make the battery stored in low temperature, dry place, especially in travel time more attention should be paid to keep the camcorder battery, and try to avoid the battery store with metal objects to prevent the occurrence of battery short-circuit; Battery could become dirty easily when travel out , that may cause the "loss", in order to avoid power drain problem happen, we must pay attention to maintaining the battery at clean both ends of the contact point and the internal battery lid. If the battery's surface is dirty, then we must use a manner and soft, dry clean cloth gently wipe the surface of the battery timely to maintain the battery clean.

When the long-term non-use of the battery, we'd best take down the battery from your digital camcorder, because at this time even if the digital video camcorder was switched off, the system will still have a low battery current output, which would reduce the battery life. Suggested discharge part of the power of the battery before long-term preservation in order to restore the initial battery capacity and discharge performance. Attention should be paid to avoid a complete discharge, because lithium batteries are a low-maintenance batteries, the part of the discharge the battery is make more durable than completely discharge , if possible regular completely discharge should be avoided, that is to say not to use the camcorder battery until automatic shutdown, recharge should be timely as long as the low electricity shortage alert.

It may have disastrous consequences If your lithium batteries have been frequent discharge completely , especially in high-current-off place or repeatedly put off, and it can not even short-circuit discharge, because such damage on the battery a far greater role. because the Internal pressure will rise and cause reversible negative electrode active material damage, even can only be part of recovery if charge, capacity will be significantly attenuated, with the passage of time, the time your lithium battery can supply will be a growing shorter!

Also need to remind everyone that in all digital camcorder accessories currently, the bad the situation of fake lithium battery manufacture and sale is especially serious because it obtained illegal profits are highest. Counterfeit lithium-ion battery performance and extremely unstable, coupled with the digital camcorder larger work current, leave the actual use time of battery much shorter than the real thing, and some have a good effect in the first-time, but after filling several electricity will find its performance has dropped drastically. Although the purchase of counterfeit batteries may be a cheaper temporary plan, but the consequence it brings is incalculable, major companies link SONY camcorder battery have also issued a statement about the use of counterfeit lithium-ion battery all the consequences, the company does not have any responsibility, therefore recommends that everyone should better to buy original lithium battery, Must be cautious before the purchase, otherwise you could bring the camcorder demage can not repair!

Well, said so many problems about the proper use and maintenance of lithium batteries, hope to be able to help everyone, rechargeable lithium-ion battery is a very important parts of digital camcorders , we have to use properly and take careful maintenance.

How To Remove the Dust in the Camera ?

With the living standards improve, digital camera / camcorder has become a common equipment of family life, but how many people know the correct maintenance of it?   

In fact, dust removal of digital electronic devices is a difficult issue for the user. Basicly manufacturers' after-sales service department can solve the problem, but the vast majority have to pay, whether you are security assurance inside or outside in the products. Faced with a lot of money about several hundred dollars asking price at every turn , many users had no choice but to retreat. Journalist ask a number of vendors' technical person about this question, summarized the main points of digital camera and other equipment dust removal as follows.   

Do not feel the parts easy to dirty first of all, pay attention to the problem on the maintenance at the beginning buy the camera, which can reduce the rate dust in bascily. Don't put the camera and the other electronic devices such as computer host together as possible as you can when it charging whitout a battery, otherwise easy to absorb substantial dust .   

In the environment have more dust should minimize the use of cameras, the directly exposed parts in camera such as lenses and LCD screens should be fitted with protection kits and protective film, the single-lens reflex camera will add UV protect mirror generally. In addition, users should develop good habits using the camera, we should try to avoid touching the LCD screen with your fingers, not only the lens. SLR camera should also pay attention to reduce the number of disassembly to avoid too much dust to enter.   

Brush with fine material. Most of today's digital manufacturers do not recommend users to conduct dust by themselves. It is reported that manufacturers usually refuse warranty in the damaged parts by the user own demolition, so If it is found that the gradual accumulation of dust in the camera usage, or stains have ingress, we also recommend users have the favorable conditions sent the camera to the experts to resolve.   

Well, for some products have years longer use, or users don't want to spend money on specialized dedusting conservation, how to deal with the dust problem? The technical staff of BenQ digital camera, told reporters that during the lens removal, should pay attention to the following questions :   

Can not use cardboard, paper towel or napkin to wipe the lens, these products are all included the wood pulp could cut or rubbed, would seriously undermine the fragile coating on camera lens . Also do not use benzene and other volatile organic solution to avoid a devastating damage to the lens.   

Right way to safeguard by ourselves is, remove dust particles with a soft brush and blown balloon, and then drop a small drop of lens cleaning fluid in the lens cleaning swab paper ----- carefully not to drop the cleaning fluid droplets on the lens directly, use clean paper swab the lens surface repeatedly, and then use a clean cotton cloth wipe the lens until the lens dry.   

Remember, do not blowing directly on the lens use mouth , because some material in the mouth may be left in the lens caused corrosion.   

The Prevention of LCD's "skin"

Currently a dedicated USB dedusting dryers available in the market, its appearance only a size of a thumb, can plug in the USB port on the computer to operate.   

For some stubborn dust particles, can be removed use electrostatic principle. For example, the pen rod non-metallic, glass, plastic handle or wood smooth objects frict heat in cotton or silk scarf to generate static electricity, then closer to the lens surface with this static objects coule absorb part of the net.   

Photographic equipment stores are currently selling a blowing balloon with a back-end air intake, front-end outlet. If users want to remove dust by themselves, can remove the camera lens, open the clear CMOS function according to the specification, reflective plate will rise and show CMOS, then blow to the CMOS use the inflatable balloon. The gas nozzle can be near more from the CMOS to enhance the effect. Note, this method does not apply for some non-SLR cameras generally .   

Apart from the lens, the digital camera's LCD screen is also very easy to accumulate dust. If stains has found on the surface display, can use some soft cloth with glass cleanerto wipe lightly, they still have to pay attention to the cleaning agents should not be dripping directly on the display surface, if the cleaning agent flows into the sophisticated airframe structure , easily lead to short-circuit and so on.   

Also do not use the hard texture paper or tissue paper to clean the screen, or easily result in scratches left. Digital camera LCD screen surface layer are anti-glare film generally, once membrane of this layer is damaged, it not be able to recover. It is a lot of plastic paper used to affixed on the screen on the market currently, the user can select to purchase and then cut to the appropriate size and pasted on the LCD screen.

LP-E6 Battery Pack in EOS 5D Mark II

As a exciting new features in CANON new DSLR, EOS 5D Mark II equiped a totally new compact battery pack called the LP-E6. This new battery teams up the camera in new ways to give photographers a precise outlook on remaining strength of a battery, not just a more powerful power supply, we can do this as well as managing multiple batteries. We’ll examine how the LP-E6 battery and the new EOS 5D Mark II perform and how to use and analyze the information it is capable of displaying on the EOS 5D Mark II’s LCD monitor.

LP-E6 appears to be nearly the same size as Canon’s long-running BP-511 series battery, but don’t let appearances fool you. The new lithium-ion LP-E6 battery pack is approximately 30% more powerful than the previous BP-511A – with 1800 milliamp-hours capacity, vs. 1390 mAh for the previous-generation BP-511A. Even though the new EOS 5D Mark II is a substantially higher-resolution camera than the previous EOS 5D, and in spite of the added performance of its DIGIC 4 processor, the LP-E6 powers the camera for 850 shots at normal temperatures (vs. 800 for the EOS 5D), based on CIPA-compliant tests performed at Canon Inc.

LP-E6 Specifications:
Rated voltage 7.2 V DC
Battery capacity 1800 mAh
Dimensions 38.4 x 21 x 56.8 mm / 1.5 x 0.8 x 2.2 in.
Weight Approx. 80 g / 2.8 oz.

Even though they appear similar, the previous-generation BP-511A batteries are not interchangeable with the new LP-E6 battery pack, and cannot be exchanged for one another. The new EOS-5D Mark II requires the LP-E6 battery pack, and cannot accept the older BP-511A or similar Canon batteries. Likewise, the new LP-E6 cannot be used in the previous EOS 5D, or other EOS bodies which accept the BP-511A battery pack.

APS-C Frame and Full Frame

What is APS-C Frame?

What is Full Frame?

Diffierent between APS-C Frame and Full Size Frame?

Twenties of the nineteenth century, after Germany production developed the 35mm (36mm × 24mm) Leica film camera for film using, the 35-mm film is also called the "Leica volume", then the world's production made more and more cameras for the 35-mm film shooting, The name "Leica volume" has been unable to adapt, so changed to "35-mm film" according to the width of the film. Until the fifties, in order to distinguish between 35-mm film and 35mm film in bulk for camera use, the code "135" has printed in the film cartridge. Later the 135 film recognized as the 35mm film, the camera used 135 film called the 135 camera.

1996, jointly by top five companies: Fuji Photo Film, Kodak, Canon, Minolta and Nikon developed APS (Advance Photo System) film system. APS developer made a radically improved on the basis of the 135 original specifications, bring full of innovation to the camera, photosensitive materials, printing equipment and related accessory products, and significantly reduce the size of the film, used the new design -- intelligent cassette, integrated the contemporary digital technology. the film become the intelligent film able to record optical information, digital information.

APS positioning to the amateur consumer market, a total of three film frame designed (H, C, P):

APS-H (HD)-type:

 frame size 30.3 × 16.6mm, for the 16:9 aspect ratio;

APS-C (classic) type:

cut each end of the left and right end in the APS-H frame, for the 3:2 aspect ratio frame size 24.9 × 16.6mm, the same ratio with 135 films;

APS-P (Panorama) type: 

cut one row both the top and bottom side of the APS-H frame, make the aspect ratio 3:1, frame size 30.3 × 10.1mm, aspect ratio 11:4.



APS three frame sizes

 
Based the cost considerations of the production and development, most of digital cameras use APS-C frame CCD / CMOS image sensor which is less than the 135 film specification, only high-level SLR digital cameras (DSLR) use the sensor have a same size to 135 film. In order to distinction facilitately, the industry man defined the 135 film size as full-frame size, so there were the diffierent between a full-frame and APS frame.

Canon EOS 50D with APS-C Size CMOS Sensor

Unlike the 18 months upgrade tradition,Canon has announced the 50D almost exactly a year after the arrival of the EOS 40D, which we're assured will be a sister-model, rather than a replacement. Recent history has seen Canon release new models every 18 months-or-so but it's been a busy year with newcomers such as the Nikon D300 getting a lot of attention in the 40D's keen-amateur/professional segment. The 50D is essentially a 40D body wrapped around a newly-developed 15 megapixel sensor that finally rectifies the situation in which Canon's XXD range trailed the company's entry-level line, in pixel terms. Canon is claiming that the new sensor's design (new manufacturing processes, redesigned photo diodes and micro lenses) mean that despite the higher resolution image noise has improved, something we'll be putting to the test later.

The other big change is the inclusion of a new, high-resolution LCD screen. 920,000 dots mean that it can convey 640 x 480 RGB pixels, making it effectively a VGA standard monitor. Three anti-reflection layers built into the screen do their best to keep it useable in bright conditions, too.

Exceptional Quality Images.
New 15.1 Megapixel CMOS sensor with improved noise reduction, wide range ISO 100-3200 (H1: 6400, H2: 12800), 14-bit conversion for smooth color tones and gradations.

The EOS 50D features a newly-designed 15.1-megapixel APS-C sized CMOS sensor which is capable of recording up to 4752 x 3168 pixels with full 14-bit A/D conversion for extremely fine tonal gradation. Ready to capture images in an instant, the sensor is designed to work with Canon's EF and EF-S lenses with a conversion factor of 1.6x. It's capable of recording at sensitivities previously too noisy for shooting in low light or subjects in motion. With a maximum ISO rating of 12800 combined with a 4-level High ISO speed noise reduction function, images that would have been impossible without the use of a strobe or flash become simple to record.

"Pixels" and "CCD size"

In digital camera specifications and the advertisement, "the number of megapixel" is the first thing put into our eyes. The thing so-called pixels, can be understood as a grid components in the photographic settings. The light color and intensity are able to receive to the camera by the unit like such a grid. Therefore, the finer the grid (that is to say, the more pixels), the more detailed particles of the photos. Accordingly the better on the performance of the details on subjects .

Camera specifications have often marked two figures "Total pixels" and "effective pixels". As the name implies Total pixels refers to a total number of pixels in digital camera . But, in fact, the external pixel in camera not used to generate image data.

Therefore, the "effective number of pixels" means the pixels except that pixels not used to genertae image ." for the "effective pixels" will be marked in the existing specifications now, so it's esay to compare this each other in the cameras.

In addition, the photographic element (CCD) size is also very important. Same number of pixels, the greater the photographic element is, the larger size of each pixel will be. The larger size the pixel hae, the amount of data can handle will increase, so the pixels will be able to distinguish the different between micro-light color and intensity. This means a wealth of photos will be able to generated .

Mid-range digital cameras use CCD between 1/2.7-in ~ 1/1.5 inch in general, high-level single-lens reflex camera's CCD will more than 1 inches some times.

Lithium or AA? Which Camera Battery Is Better

Why Lithium Battery

Lithium batteries have a small size, light weight,short charging time . At present, thin shape, fashion beautiful card DC basically using this battery.

AA battery have a large size, is also heavier, so the camera using this battery correspondingly have a larger volume.

AA batteries discharge time become shorter after a dozen times. Lithium batteries can be used a long time relatively, My lithium batteries used 5 years.

Most non-brand AA batteries are so poor that can not be used for shooting, and the good battery is too expensive, and can not charge.

Half of the lithium battery recharge only 2 hours, AA batteries need to charge even one-day.

Why AA Battery

Lithium battery capacity is not great, the general is 600-700mah, only a few have 1000mAh. AA rechargeable nickel-metal hydride batteries have reached at 2500 mAh.

The current lithium batteries have high price, usually spend 50,60 dollars, so it is a large one-time investment of money to prepare a backup battery. If there is no backup battery when encounter no electricity in the shooting, it can only "hope King can not afford", nothing you can do.

If AA battery encountered such a situation, you can buy a temporary contingency alkaline AA batteries everywhere available, there are not hard to buy even the most remote scenic spots. This is obviously a big advantage of AA battery.

If I bought a DC produced few, a few years after the battery match with it might have to stop product, the lithium battery so expensive, can you buy a lot of pieces back-up placed at home?The lithium battery must be recharged in the machine, inconvenient.

I used number of cameras different, feeling the AA battery better, Machines with lithium batteries built in, with the passage of time and aging, consumption declining and battery needs to be replaced.


Not Very Important

Lithium electricity and Ni-MH battery both have not strong memory effect.

Use lithium batteries or AA batteries? in fact, depends on the choice of camera. If you decided to buy a card machine, it basically decided that you can only choose lithium batteries. If you choose manual, feature-rich camera like Canon A-series, generally speaking, you have to choose AA batteries. Ordinary DC use AA is better.

Remember: Which battery to buy is not the most important reason make you to buy the camera.

Tips in Camera Battery Using and Maintenance

Digital camera is an "electric tiger", which eat a lot of electric, if your battery does not match or pay no attention to saving, the battery will run out when you does not take a few photos. Battery usage could be save by following approach: first, avoid using zoom operation unnecessary; second, to avoid frequent use of flash, flash is a big electrical consumption, we must using as fewer as fewer as we can; Third, use the viewfinder will be better than the LCD when adjust the screen and composition browser. Because most digital cameras are consume more electricity due to open the LCD viewfinder, shut down it will enable the battery backup time growth in two or three times; Fourth, to minimize the use of Continuous function. Most of continuous functions of digital cameras using the cache built-in to preserve digital photos temporarily. Lot of electricity required if use these caches regular. Therefore, to reduce the use of Continuous and dynamic function of the video clips shot will take great help on the power save.   



A lot of tips needed also in rechargeable batteries, rechargeable batteries just bought have very low or no electricity generally, should be charged before use. The charging time depends on the charger and battery used, and the factors such as voltage stability. If this is a battery the first time to use, lithium-ion battery must be charged more than six hours, Ni-MH battery must be more than 14 hours, or you will short the battery life. Normally few charge / discharge process would be taken in order to achieve optimum efficiency. And to ensure the battery life do not charge when when there is residual power in battery. Battery will be very hot After fully charged, loaded in the camera after it cool.
  
Battery cleaning is necessary to avoid the problem of electricity wastage. Maintain both ends of the contact point and the internal battery lid in the battery clean, use a soft, clean dry cloth graze if necessary, do not clean your digital camera, batteries, or charger use sexual or chemical cleaning, such as solubility things. The batteries must be to remove from your digital camera if you plan not to use a digital camera a long time, and full discharge it (some of charger with this feature, if not available, use low resistance electrical short the battery until all the power discharged), stored in dry, cool environment, and not to store the battery with metal objects. Store a battery full charged, we can't put it in purse, pocket, bag or other container with metal objects in to prevent short circuit.

How to Identify Fake Mobile Phone Batteries

Generally genuine mobile phone batteries have following exterior features:      

1, Battery labels using the second printing technology, in a certain light, the color of the bar code part is black than other parts see from the slope, feels with hands, convex than the other parts, all Motorola original batteries have this kind characteristics.      

2,  Zoned with light metal objects, there are across traces similar to pencil on white Department of battery labels surface. 

3, Battery casing made from a special material, very strong, not easily damaged,  The battery unit can not opened by general means.      

4, Batteries have tidy appearance, no extra burr, a certain degree of roughness on the outer surface but feel comfortable, inner surface smooth,  fine longitudinal scratches could be see under the light.      

5, Battery electrodes and cell phone battery sheet have the the same width, "+""-" signed below the battery electrode,  The isolation materials between the charger electrode and the case material are the same, but not integrated.      

6, The battery could be install in the phone comfortability.      

7, Compression part of the battery lock-bit come out appropriate, firmly.      

8, Battery labels clear handwriting, have the battery accessorices model corresponding to this battery.      

9, battery manufacturers should outline clear, anti-counterfeit mark have a good brightness, three-dimensional look. 

10, Have the "sawtooth" burr on the edge of battery labels, this is particularly suited to distinguish between Ericsson Series battery.

Two Important Parameters of The Battery

First of all, I'd like to introduce you two important parameters of the battery - voltage and battery capacity, these two parameters are important criterion in measure of battery performance and attributes.      

Circuit voltage is the electric potential difference between two points. The unit of voltage is V (volts), general one alkaline battery have a voltage of 1.5V, nickel-cadmium batteries and nickel-metal hydride battery are 1.2V, while the lithium-ion battery is 3.6V (a small number of manufacturers' lithium-ion battery have a rated voltage of 3.7V).      

Battery capacity refers to the amount of electricity the battery can stored, express used unit mAh (milliampere hours). We can see it is a composite unit, constitutes multiply by the current units and the time unit. For example, an fully charged battery with 70mA current can be discharge sustained 10 hours in ideal situation, we know that this battery capacity is 700mAh from the section multiplied by discharge current and time, in theory, if discharge it in 700 mA you can only use 1 hours (battery capacity divided by discharge current). In large-scale batteries we would normally use a larger unit of voltage like Ah (An pm) to express (1Ah = 1000mAh).
