discharge. Frequent full discharges should be avoided if 

possible. Instead, charge the battery more often or use a 

larger battery.

The brand-new NiCd battery pack is partially useful 

with its capacity until it has been subjected to 10 or more 

charge cycles in any case. The cyclic process of charge 

and discharge will lead to optimize the capacity of battery 

pack.
