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?
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:
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:
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.

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.

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).
