Self-Discharge - The loss of useful capacity of a battery on storage due to internal chemical action (local action).
Parallel - Term used to describe the interconnection of cells or batteries in which all the like terminals are connected together. Results in increased capacity.
C-Rate (also see Hourly Rate) - Discharge or charge current, in amperes, expressed in multiples of the rated capacity. For example, C/10 discharge current for a battery rated at 1.5 Ah is:
Circuit breaker (battery) - DC circuit breaker that protects the battery of a UPS.(back)
Specific Energy - The ratio of the energy output of a cell or battery to its weight (Wh/kg). This term is used interchangeably with gravimetric energy density.
Battery cells - The interconnected battery elements that supply electrical power created by electrolytic reaction.
MTTR (Mean Time To Repair) - Mathematical calculation (or statistical average if available) of the time required to repair a device.
