where <i class="emphasis">I</i> = current, A<i class="emphasis">      C</i> = numerical value of rated capacity of a battery in ampere-hours (Ah)<i class="emphasis">      n</i> = Time in hours for which rated capacity is specified<i class="emphasis">      M</i> = multiple or fraction (of <i class="emphasis">C</i>)

For example, the 0.05 C or C/20 discharge current for a battery rated at 5 Ah at the 0.2 C or C/5 rate is 250 mA.

Conversely, a battery rated at 300 mAh at the 0.5 C or C/2 rate, discharged at 30 mA, is discharged at the 0.1 C or C/10 rate, which is calculated as follows:

A-B

Adsorption

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

Accumulator

See SECONDARY BATTERY.

Activated Stand Life

The period of time, at a specified temperature, that a battery can be stored in the charged condition before its capacity falls below a specified level.

Activation

The process of making a reserve battery functional, either by introducing an electrolyte, by immersing the battery into an electrolyte, or by other means (see Part...
