Current Drain - The current withdrawn from a battery during discharge.
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.
Limiting Current - The maximum current drain under which the particular battery will perform adequately under a continuous drain. The rate is based on whatever drain rate reduces the running voltage to 1.1 volts.
High Voltage Spike - Rapid voltage peak up to 6000 volts with a duration of 100mS to 1/2 cycle.
