Depth of discharge

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.")

"Over voltage is a state where the battery voltage exceeds the manufacturer's/supplier's rated values or specified conditions. Over voltage can disrupt the normal functioning of the battery and/or lead to hazardous incidents.Note: When discussing electrodes, it is referred to as overpotential."

An appropriate approximate voltage used to identify or characterize a battery or an electrochemical system.

The capacity released by the internal active material of a battery during discharge divided by the mass of the active material.Note: Specific capacity is typically expressed in milliampere-hours per gram (mAh/g). Sometimes, the calculation of specific capacity includes the mass of all non-active materials, such as conductive additives and binders.

The capacity value of a battery cell, module, battery pack, or system measured under conditions specified by the manufacturer and declared by the manufacturer.Note: Rated capacity is typically expressed in ampere-hours (Ah) or milliampere-hours (mAh).

The difference in potential between the positive electrode and the negative electrode under a no-load condition.
