How to choose a battery charger ?
As you choose your battery charger, you also need to think about:
How many batteries do you need to charge at once?
Battery chargers can fit in between two to eight batteries to charge simultaneously. If you’re likely to want to charge a single battery, check the specifications of the battery charger to see whether it can.
What battery sizes do you want to charge?
Most chargers are compatible with AA and AAA batteries. If you want to charge 9V, C or D-size batteries, check carefully for a model that can.
Some battery chargers have lights to indicate when batteries are charged. You can check the charging status in anytime in case the batteries overcharged.
* If you think to choose a suitable battery charger is annoying, highly recommend you buy the same brand charger when you buy the rechargeable batteries!
