Reference test current

The maximum voltage allowed during the normal charging of a battery cell, module, battery pack, or system.

A continuous, long-duration, regulated low-current charging process used to compensate for self-discharge effects and maintain a battery in an approximate state of full charge.Note: Trickle charging is used to offset self-discharge effects to keep the battery in an approximate state of full charge.

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.")

The capacity that can be discharged from a battery after it has been fully charged under specified conditions, allowed to stand for a specified time at a specified temperature, then fully recharged, and discharged again.

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.

Refers to the voltage between the positive and negative terminals of a metal-cased battery with respect to the battery's outer shell. Generally, this is determined by the battery manufacturer based on their own manufacturing processes and sets the qualified standards.
