AA Battery Charger

An AA battery charger is a gadget that is used to recharge NiCD or NiMH batteries. AA refers to the size or type of battery. Compared to AAA battery, it is bigger and more commonly used. There are many brands available in the market today like Sanyo, Sony, Energizer, LaCrosse and Panasonic to name a few.

If you have gadgets such as digital camera, music player or even household items like a wall clock or toys, having an AA battery charger can save you on costs since AA alkaline batteries are usually good for one or two uses only. The rechargeable types, although more expensive, can last for many uses.

An AA battery charger usually comes with a free pair or two of batteries. Most types can charge both AA and AAA. Travel chargers are smaller in size and offer shorter charging time which usually ranges from as fast as one hour to two. There are chargers that can accommodate more than four batteries simultaneously.

Sophisticated models of AA battery chargers include a small LCD display that lets you monitor the charging time, charging current, voltage, accumulated capacity and discharge current. Each battery, despite being charged simultaneously with another, can be assigned with different charging rates so older and newer ones can be charged accordingly.
