Inverter - UPS subassembly that recomposes a sine-wave output (regulated and without breaks) using the DC current supplied by the rectifier-charger or the battery. The primary elements of the inverter are the DC/AC converter, a regulation system and an output filter.
Overdischarge - The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
Voltage Delay - Time delay for a battery to deliver the required operating voltage after it is placed under load.
Current Density - The current per unit active area of the surface of an electrode.
Hazardous Waste - Waste which is classified as "hazardous" (i.e., potentially harmful to the environment) by the government.
Depth of Discharge - The ratio of the quantity of electricity (usually in ampere-hours) removed from a battery to its rated capacity.
Current (inrush) - Temporary current observed in a network when electrical devices are energized, generally due to the magnetic circuits of the devices. The effect is measured by the current's maximum peak value and the rms current value it generates.
