Short-circuit current

Latest updated: Jan 24, 2024

The maximum current that a battery can deliver to an external circuit with zero resistance or with the battery voltage reduced to near zero volts.

Note: Zero resistance is an imaginary condition, and in reality, the short-circuit current is the maximum current that flows in a circuit with a resistance significantly lower than the internal resistance of the battery.

Self-discharge rate

Translation: A physical quantity used to describe the rate of self-discharge of a battery, also known as the "K-value." It is calculated as the difference in open-circuit voltage (OCV) between two tests divided by the time interval between the two voltage tests, expressed as K = (OCV1 - OCV2) / ΔT.
