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.")
