IEC (International Electrotechnical Commission) - Advisory organization that draws up international standards in the electrotechnical field.
Capacity - The total number of ampere-hours or watt-hours that can be withdrawn from a fully charged cell or battery under specified conditions of discharge.
Volumetric Energy Density - The ratio of the energy output of a cell or battery to its volume (Wh/L).
Voltage Delay - Time delay for a battery to deliver the required operating voltage after it is placed under load.
RMS Voltage - The range of usable voltage + or - 170 VAC.
Top-Up Charge - A low rate charge following the main charge, designed to ensure maximum capacity.
Tolerance in % - Limit for allowable variations for a given quantity, expressed as a percent of the rated value.
