We are used to thinking of a battery as a very simple thing. It is basically a device that converts chemical energy to electrical energy and vice versa. But understanding all the battery terminology can be challenging. Below you can find a summary, aiming to introduce you to important battery terminology.
- Ampere Hours
An ampere hour is a unit of measure for a battery’s capacity. One ampere-hour is a current of one ampere flowing for one hour.
Battery capacity is the number of ampere-hours a battery can carry under certain conditions of discharge.
Electromotive force or electrical potential difference, expressed in volts (V).
A battery cell is a electrochemical unit used to store electrical energy. It is generally on the order of one to six volts.
Charge is the process of restoring electrical energy to a cell or battery.
Discharge occurs when a battery is delivering current.
The process of discharging and then recharging a battery.
- Cycle Life
The number of cycles a cell or battery provides before failure. The term is generally used to specify a battery’s expected life, because the number of cycles affects battery life more than the passage of time.
- Cycle Use
When a battery is being used as a direct power source on a regular basis and it is being discharged and subsequently recharged. Example: electric scooter battery.
- Standby Use
When a battery is being used as a back up power. Example: a battery in a UPS unit.
- Battery Terminals
Battery terminals are used to connect a battery to its application or to a charger. You can view the most common SLA battery terminals here.
