Open-Circuit Voltage (OCV) - The difference in potential between the terminals of a cell when the circuit is open (no-load condition).
Micro-outage (or micro-interruption) - Total loss in the supply of power for 10 ms.
Pulse Current - A periodic current drain of higher than normal drain rates.
IR Drop - A voltage drop associated with the electrical resistance (R) of a battery or current flow (I). The voltage drop is the product of the current (in amperes) and the resistance (in ohms).
Primary Battery - A battery which is not intended to be recharged and is discarded when the battery has delivered all of its electrical energy.
Dry Cell - A cell with immobilized electrolyte. The term "dry cell" is often used to describe the Leclanche cell.
Memory Effect - A phenomenon in which a cell or battery operated in successive cycles to the same, but less than full, depth of discharge temporarily loses the rest of its capacity at normal voltage levels.
