All modern video cameras and SLRDSLR cameras operate on batteries - built http://www.cheapnmdshoesoutlet.com/ , which are created by the manufacturer for the specific device model or standard types AA赂 less - AAA. Built-in rechargeable batteries included, but their power is usually minimal, and therefore, the charge for long enough, so it is advisable to have left another set. However, from the many users of disposable camera battery also eventually refuse - batteries of the same type Cheap Adidas NMD R2 , of course, are much more expensive, but can withstand a few hundred charge cycles and may eventually cheaper. In this review we will talk about the main types of batteries and their basic characteristics.

The easiest way to choose the battery for the camera or video camera - to look at the instructions in the device, where the manufacturer results in very specific recommendations on this issue. However, the "native" battery often too expensive or delivery of a suitable model will have to wait a few weeks. At the same time on the market are well represented counterparts from other brands, which may be different capacity and price Cheap Adidas NMD R1 , but with the main objective - powered devices - they are coping quite well. What should we look for when purchasing compatible camera battery ?


Finger batteries


AA batteries (at least - AAA) is usually installed on low-cost cameras, at least - on the SLR cameras. For professional use only models with booster - an electronic device that increases the voltage, and stabilizing supply ichnye model penlight batteries have a maximum capacity and output voltage. Capacity defines the number of on-off, as it is at that time accounted for the largest energy consumption, and the number of images or the length of video shooting on one set of batteries. On sale today presented 1500-3200 mAh capacity camera battery and more.


Output voltage - characteristic, which depends on Cheap Adidas NMD White , including whether it is the device or not; If this indicator is too low, the electronic camera system thinks that the battery is dead and must be replaced.


In general, it is worth noting that an objective assessment of AA batteries or that the manufacturer can be given only if the use of an electronic analyzer (which do not, if the batteries are packaged in plastic) or in the laboratory. The marking, which is applied to the goods often does not coincide with its real characteristics, so it is recommended to give preference to products of famous brands: energizer Cheap Adidas NMD Black , Duracell, Panasonic, Kodak and others. By the way, the Russian batteries "Our strength" of the independent research can compete with batteries of world famous brands and a number of indicators even surpass them.


Special camera battery


For professional photo and video capacity penlight batteries is usually not enough, so they are installed higher-capacity camera battery and power. Typically, the battery is suitable for a particular model of one or more camera models Cheap Adidas NMD Mens , so in this case it is necessary to start by examining information in the labeling or instructions. Most manufacturers offer a camera or camcorder several battery models of the same shape and size, but of different capacity (expressed in milliamperes per hour mAh, mAh). Original batteries are much more expensive counterparts from China and other Asian countries, however, and the reliability of their higher - the camera battery is kept longer charge-discharge cycles.


Chemical composition


The cheapest are alkaline nickel-cadmium and nickel-metal hydride batteries (usually AA size). Their lack of - memory effect, because of which the battery must first be fully discharged and then recharged; charging significantly reduces its capacity. In addition Cheap Adidas NMD Womens , the range of the normal operation of alkaline batteries is low: -10 to +40 degrees Celsius. Lead-acid batteries are more expensive, are more reliable, but if completely discharged out of the system.


Lithium-ion and lithium-polymer camera battery, on the contrary, should be charged when their residual capacity is at least 5-10%; otherwise their capacity drop by 20% or more. They are effective at high and low temperatures, are more durable than saline and alkaline Cheap Adidas NMD Shoes , however, and are much more expensive, besides the only compatible with certain models of photographic and video equipment. Another advantage of lithium-ion and lithium-polymer batteries: the maintenance of the required level of voltage throughout the run time and are not subject to self-discharge. Note that these batteries are often confused with lithium batteries designed for one-time use: they are usually worth marking Lithium Non-Rechargeable or simply no inscriptions Rechargeable.


If you allow the shape and polarity of the battery compartment, and in the recommendations of the manufacturer there is no ban on the use of nickel-cadmium or nickel-metal hydride batteries can be replaced by AA lithium-ion or lithium-polymer camera battery size CR-V3.

Choosing the charger is determined by the type of battery. As a rule, special batteries for cameras and camcorders are supplied with charger; to acquire another, follow the instructions to the technique recommended by the manufacturer or batteries. For rechargeable AA battery charger selection is determined not only by their standard size Cheap Adidas NMD , and chemical composition: Alkaline batteries are required to model function fully discharged before recharging for lithium-ion and lithium-polymer - appropriate types of equipment. Note that the model for fast charging, as a rule, will shorten the battery life for the slower - for maximum efficiency set of batteries for a long time.
