Absorption
The taking up or retention of one material by another by chemical or molecular action.

Alkaline
A primary battery (non-rechargeable) often used in electronics applications requiring heavy currents for long periods of time (i.e.: cd players, radios, etc.). Alkaline batteries can deliver 50-100% more total energy than conventional Carbon/Zinc batteries of the same size, hence their popularity in consumer applications.

Alloy
A mixture of several other metals or a metal and a non-metal.

Ambient Temperature
The average temperature of the surroundings.

Ampere-Hour Capacity
The quantity of electricity measured in ampere-hours (Ah) that may be delivered by a cell or battery under specified conditions.

Anode
The electrode in an electrochemical cell where oxidation takes place. During discharge, the negative electrode of the cell is the anode. During charge, the positive electrode is the anode.
