Rated capacity

The voltage between the two terminals of the battery during discharge.

Electrode polarization accompanying electrochemical reduction reactions.

The voltage across the positive and negative terminals of the battery during discharge at the operating current.

Discharge multiplier is a measure of the speed of discharge, which refers to the value of the current required for a battery to discharge its rated capacity within a specified time period. (It is numerically equal to a multiple of the rated capacity of the battery, i.e., "discharge current/rated capacity of the battery = discharge multiplier", usually denoted by the letter C.) Similarly, the charging multiplier is a measure of the speed of charging, i.e., "charging current/rated battery capacity = charging multiplier.")

Reversal of the polarity of battery electrodes. Typically caused by overdischarge of a low-capacity battery in a series connection.

A charging state in which, under selected conditions, all available active materials do not significantly increase the capacity during charging.
