Ohm
A measure of resistance that causes one volt to produce a current of one ampere.

Open-Circuit Voltage
The difference in potential between the terminals of a cell when the circuit is open (no-load condition).

Overcharge
The forcing of current through a cell after all the active material has been converted to the charged state, that is, continued charging after reaching 100 percent state-of-charge.

Overdischarge
The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
