It’s a proven fact that digital cameras are one of the most high-drain gadgets you can slip in a pocket. Gone is the film era, when the camera just needed a small amount of power to fire the shutter, and activate the focus and metering especially for more advanced cameras. Nowadays most of digital cameras are equipped with a colour LCD monitor to preview or line up the shot, and this needs lots of power.
Standard AA batteries (non-rechargeable AA) are nothing but light snack to the power-hungry digital camera. The batteries can be drained of their power quite quickly. Thanks to the advancement in technology people now have the option to use rechargeable batteries.
The rechargeable AA batteries, although more expensive, can last for many uses. You can recharge the batteries using an AA battery charger.
An AA battery charger is a compact device that is used to recharge NiCD or NiMH batteries. The charger puts energy into a secondary cell, a rechargeable battery, using an electrical current. AA correlates with the size or type of battery.
There are many factors to consider when purchasing a battery charger. You have to make sure the charging technology is compatible with your batteries. Fortunately, an AA battery charger usually comes with a free pair or two of batteries.
Also it’s important to know what features you need from a battery charger. More sophisticated AA battery chargers are equipped with a small LCD monitor which allows you to monitor the charging current, discharge current, charging time, voltage and accumulated capacity.
Overall, an AA battery charger can save you money in the long run since non-rechargeable AA alkaline batteries are usually good for one or two uses only. You can choose a charger from many brands available in the market today like Energizer, Sanyo, Sony, Panasonic and LaCrosse.
