Midpoint Voltage - The voltage of a battery midway in the discharge between the start of the discharge and the end voltage.
Passivation - The phenomenon by which a metal, although in conditions of thermodynamic instability, remains indefinitely unattacked because of modified or altered surface conditions.
Current Drain - The current withdrawn from a battery during discharge.
Discharge Rate - The rate, usually expressed in amperes, at which electrical current is taken from the battery.
Power source (alternate) - Backup source used in the event of a mains failure. The connection time and the duration of the source depend on the type of source used. (back)
PWM (Pulse Width Modulation) - Inverter high-frequency chopping technique using a means of regulation enabling rapid modification of pulse widths over a single period, thus making it possible to maintain the inverter output within tolerances even for non-linear loads.
1.5 Ah/10 = 150 mA (A cell's capacity is not the same at all discharge rates and usually increases with decreasing rate.)
