Ah
/ Amp Hours
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. The more 'Amp Hours' the longer the run time.
You can also think of Amp Hours as gallons of gas.
Capacity
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
the required voltage.
Capacity is the gallons of gas a tank can hold
Cell
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.
Charge
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.
Cycle Life
The amount of times a battery may be charged and discharged. Every
time a battery is charged and discharged it uses one cycle.
Discharge
The release of energy by the battery.
Memory
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
Rated Capacity
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.
Self-Discharge
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.
Voltage
Units of measuring electric potential, all batteries are rated in
volts DC. (Direct Current). This determines how much energy is needed
to power your equipment.
Amps
Units of measuring electrical current.
