CONFIRMING CHARGE CURRENT
08
It is critically important to understand the maximum charging current
for the battery pack to be charged. Excessive charge current can
significantly reduce the life of a battery, or in severe cases a fire or
explosion.

The charge and discharge current of a lithium battery is determined
by its “C” rating. Most batteries indicate the C rating of the pack on the
main label. Multiply the C rating of the battery pack by the capacity to
determine the safe and proper charge current. For example, a 5000mAh
battery with a 1C rating means that the maximum charge rate should be
5000 (capacity in milliamps) X 5 (C rating) = 5,000mAh. Therefore, the
maximum charge rate for a 5000mAh 1C lithium battery should be 5A
(5,000mAh).
If it is not possible to determine the C rating, please assume that the
pack is 1C and use that value to calculate a safe charge rate. Keep in
mind that batteries vary, and therefore charging times will vary.
