Polarization - The lowering of the potential of a cell or electrode from its equilibrium value caused by the passage of an electric current.
Switching Transients - Rapid voltage peak up to 20,000 volts with a duration of 10mS to 100mS.
Energy Density - The ratio of the energy available from a battery to its volume (Wh/L) or weight (Wh/kg).
Reversal - The changing of the normal polarity of a battery due to overdischarge.
Self-Discharge - The loss of useful capacity of a battery on storage due to internal chemical action (local action).
Electromagnetic compatibility - Possibility of a device to operate normally when installed near other devices, given the disturbances emitted by each device and their mutual sensitivities.
Output (rated) - Apparent power Pn that the UPS can deliver under given load conditions (power factor = 0.8).
