What does K or C mean in a battery?
The capacity (K or C value) of a battery depends on the current with which it's discharged. The lower the discharge current, i.e. the longer the discharge time, the greater the usable capacity. And vice versa, the greater the discharge current, the less the available capacity. The “K or C” index always indicates the discharge time in hours.
