Reversal - The changing of the normal polarity of a battery due to overdischarge.
Intermittent Test - A test during which a battery is subjected to alternate periods of discharge and rest according to a specified discharge regime.
Short-Circuit Current (SCC) - The initial value of the current obtained from a battery in a circuit of negligible resistance.
Transformer short-circuit voltage (Uscx %) - Relative measurement (%) of the internal impedance of a transformer. This short-circuit impedance is commonly called the short-circuit voltage because it is measured during a short-circuit test (shorted secondary winding subjected to a current set to In). For most common three-phase transformers, this value ranges between 3 and 6%.
Battery cells - The interconnected battery elements that supply electrical power created by electrolytic reaction.
Wall-less Design - A battery design where the structural support for the cells is formed by an open plastic framework.
Gassing - The evolution of gas from one or more of the electrodes in a cell. Gassing commonly results from local action (self-discharge) or from the electrolysis of water in the electrolyte during charging.
