Batteries fulfill the high power
requirements of digital cameras. They are also the sole driving force in
them. Digital cameras are becoming smaller by the day, which has
developed a need to develop smaller and smaller batteries. The small
batteries are also required to have the capacity to feed these cameras
for a considerable length of time.
Few types of batteries dominate the world of digital cameras. AA, CR-V3,
CR2 and AAA batteries are the most readily available types available in
the off-the-shelf category. These are easily available everywhere. The
CR2 and CR-V3 batteries are meant for single use. They are lithium based
and commonly used in camcorders. The AA batteries are more commonly used
everywhere. However, these are capable of generating power for a short
time only. Most consumers have shown a preference for AA Nickel metal
hydride batteries. These are popularly called NiMH and provide enough
power.
They are also rechargeable. Lithium ion
batteries generate even more power than NiMH batteries, which tend to
discharge when out of use. These are available in Ah and mAh ratings,
Ampere-hour and milli-ampere-hour ratings, which affect their lasting
quality in terms of time taken to use. However, off the shelf batteries
are compatible with mid-range consumer model cameras and certain low -
end models only. Very few DSLR cameras are known to accept them. The
best alternatives to these are Sigma SD10 and RCR-V3 lithium-ion
batteries.
Proprietary battery formats come under the second category. These are
custom made for manufacturers, and work as OEM or after market
replacement parts. All proprietary batteries only take a particular
number of recharges. After that the battery life begins to degrade. The
typical cycle is up to five hundred recharges. All proprietary batteries
are lithium ion and give good performance considering their tiny size.
Low-end consumer model cameras and the high-end professional models,
both are known for using lithium ion batteries.
Limited battery life is a huge problem with digital cameras. The use of
LCD viewfinder hastens the consumption of camera batteries. Most digital
cameras are now sold with rechargeable batteries and battery chargers.
These cost between $30 and $100. Cameras that come with these are
typically sold at a higher price to include the above charges. It is
advisable to keep a stock of extra batteries on hand. Another option can
be to buy an extra rechargeable battery pack.
Sony, Nikon, Canon, JVC, Eforce, Casio, Olympus, Panasonic, Pentax, Hama,
generic, Minolta and Rico are some well-known manufacturers of camera
batteries. The most popular among them are Canon, Sony, Nikon and JVC.
Besides these there are many unbranded battery manufacturer in the
world. Fuji film has also gained some visibility as a battery
manufacturer. It is very difficult for a common man to identify the
right batteries for their cameras. Rechargeable options, which suit the
client, disappear from the market in no time due to new companies
entering digital camera battery manufacturing all the time. It is very
to make a thorough study of available batteries and their compatibility
with the camera you intend to purchase.
