Cycle Life - The number of cycles under specified conditions which are available from a secondary battery before it fails to meet specified criteria as to performance.
Ambient Humidity - The average humidity of the surroundings.
Circuit breaker (battery) - DC circuit breaker that protects the battery of a UPS.(back)
Internal Impedance - The opposition exhibited by a circuit element (cell or battery) to the flow of an alternating current (a.c.) of a particular frequency as a result of resistance, induction and capacitance.
Wall-less Design - A battery design where the structural support for the cells is formed by an open plastic framework.
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.
Ampere-Hour Capacity - The quantity of electricity measured in ampere-hours (Ah) which may be delivered by a cell or battery under specified conditions.
