Cellular Battery Terms
Amperage / Amp Hours (Ah)
Represents the amount of energy a battery can hold. This measurement
helps determine how long the battery will power the equipment it
is used in. Generally speaking, the more 'Ah's' the longer the run
The amount of energy a battery can store. Measured in Amp Hours
or Milliamp Hours, this is the length of time the battery can supply hgh
the required voltage.
A single battery canister. Usually grouped together with other
cells to form battery packs of different voltages and amperages.
Example: one NiCD cell is 1.25 volts therefore ten cells packaged
together makes a 12.5 volt battery pack.
The process of putting energy into a battery.
"Conditioning A Battery"
A process that utilizes a series of heavy discharges and recharges,
on a battery to assure optimum performance.
The amount of times a battery may be charged and discharged.
Every time a battery is charged and discharged it uses one cycle.
The release of energy by the battery.
The term used to describe the capacity loss and subsequent voltage
drop in a battery due to constant or repetitious charging and incomplete
discharging. This results in a loss of run-time.
Milliamp Hours (mAh)
Refers to battery capacity. 1/1000th of an amp.
Example 1.8Ah = 1800Mah
Measured in 'Ah' or 'Mah' capacity is determined by the cell
manufacturer. This number is then used to determine run time and
is also in warranty policies.
The process of a battery releasing its energy without being
used. This can occur by just sitting on the shelf. Most batteries
self-discharge about 1 to 2 percent each day.
Units of measuring electrical current, all batteries are rated
in volts DC. (Direct Current). This determines how much energy is
needed to power your equipment.
