Continuous Test - A test in which a battery is discharged to a prescribed end point voltage without interruption.

Series - The interconnection of cells in such a manner that the positive terminal of the first is connected to the negative terminal of the second, and so on, resulting in increased voltage.
Hazardous Waste - Waste which is classified as "hazardous" (i.e., potentially harmful to the environment) by the government.
Micro-outage (or micro-interruption) - Total loss in the supply of power for 10 ms.
Capacity - The total number of ampere-hours or watt-hours that can be withdrawn from a fully charged cell or battery under specified conditions of discharge.
