- A smart battery charger, also referred to as a microprocessor-controlled charger, recharges A, AA and AAA batteries to their full potential, without overcharging or undercharging them. Overcharging or undercharging can shorten the life of a rechargeable battery, making it unusable much more quickly than charging it to its exact capacity.
- Having a smart battery charger works to your advantage by saving you money in the long run, as you will spend less overall money on batteries than you would if you used a standard battery charger or one-time-use batteries. Most smart chargers can hold up to 12 batteries, which means that if you place batteries in the charger at regular intervals, you should have enough for nearly any application or occasion.
- Smart chargers and rechargeable batteries can be somewhat expensive upfront, and may not seem like a worthwhile investment. If you are the type of person who does not use batteries regularly, a smart charger may not be right for you.
