Discharge or current rate in amperes; numerically equal to rated capacity of a cell in ampere-hours.

The quantity of electricity delivered by a battery under specified conditions, usually expressed in ampere-hours

See Reconditioning.

Reduction in cell capacity due to nonstandard charging or discharging parameters such as cell temperature, current, and discharge voltage cutoff. See also Failure, Functional.

Reduction in cell capacity from .as new. value, under standard rating conditions, not recoverable by reconditioning. See also Failure, Permanent.

See Nominal Capacity.

Capacity remaining at particular point in time after any set of operating conditions, usually including a partial discharge or long rest.

See Capacity, Temporary Loss Of.

Reduction in cell capacity that is recovered when the cell is subjected to several reconditioning cycles.

See Ampere Hour Capacity.

The battery box or enclosure which contains the cells and associated connectors and hardware.

as pertaining to Concorde Battery Corporation

An electrochemical device composed of positive and negative plates, separator, and electrolyte which is capable of storing electrical energy. When encased in a container and fitted with terminals, it is the basic building block of the battery.

Reversing of polarity within a cell in a multi-cell battery due to over discharge.

The conversion of electrical energy from an external source, into chemical energy within a cell or battery.

The rate at which current is applied to a secondary cell or battery to restore its capacity.

The tendency of a charged cell or battery to resist self-discharge.

The condition of a storage cell or battery in terms of the remaining capacity.

Device capable of supplying electrical energy to a battery.

The process of converting electrical energy to stored chemical energy.

Ratio of the capacity delivered on discharge, after being fully charged, to the capacity needed to restore full charge to the cell or battery.

RG batteries have one-way cell vent valves designed to relieve excess positive internal pressure. Occasionally, when the atmospheric pressure is greater than the internal pressure of the battery, caused by rapid decrease in altitude, the battery case may become temporarily concave.

An electrically conducive bar or wire which joins individual cells together in a battery.

Charging technique where the output current of the charge source is held constant. Warning! This procedure may damage the battery if performed on a repetitive basis.

Charging technique where the output voltage of the charge source is held constant and the current is limited only by the resistance of the battery.

The cell enclosure in which the plates, separator and electrolyte are held. It is made up of the cell jar and cover that are permanently joined.

Undesirable element, usually in the electrolyte, which reduced the capability of the cell. In vented cells, contaminants can be introduced by use of tap water or operation without vent cap.

Electrochemical or electronic device, capable of integrating current time, used for charge control.

Voltage or a cell or battery opposing the voltage of the charging source.

The rate of flow of electricity. The movement of electrons along a conductor. It is comparable to the flow of a stream of water. The unit of measurement is an ampere.

The amount of electric current passing through a given cross-sectional area of a conductor in amperes per square inch, i.e: the ratio of the current in amperes to the cross-sectional area of the conductor.

Battery voltage reached at the termination of a discharge. Also known as end point voltage or EPV.

On sequence of charge and discharge.

For secondary (rechargeable) cells or batteries, the total number of charge/discharge cycles before the cell or battery becomes inoperative.
