Discharge Rate - The rate, usually expressed in amperes, at which electrical current is taken from the battery.
Voltage Reversal - The changing of the normal polarity of a battery due to overdischarge.
Volumetric Energy Density - The ratio of the energy output of a cell or battery to its volume (Wh/L).
Ambient Humidity - The average humidity of the surroundings.
Current (float) - DC current that maintains the battery at nominal charge, corresponding the float voltage. This current compensates open circuit losses.
Anode - The electrode in an electrochemical cell where oxidation takes place. During discharge, the negative electrode of the cell is the anode. During charge, the positive electrode is the anode.
Thermistor - A temperature sensitive resistor, usually made from specially processed oxides.
