Charging batteries

Determining the charge current:

Before building the kit, one must determinate how much current will be used to charge the battery or bat-

tery pack.

It is advisable to charge the battery with a current that is 10 times smaller then the battery capacity, and to

charge it for about 15 hours. If you double the charge current , then you can charge the battery in half the

time.

Example:

A battery pack of 6V / 1000mAh can be charged with 100mA during 15 hours. If you want to charge faster,

then a charge current of 200mA can be used for about 7 hours.

Using a charge current of 1/10 of the capacity will expand the lifetime of the battery. The charge time can

easily be doubled without damaging the battery.

CAUTION: The higher the charge current, the more critical the charge time must be checked.

When faster charging is used, it is advisable to discharge the battery completely before charging.
