Glossary Term: mA. Definition. Milliampere, or milliamp: 1/1000 of an Ampere. Ampere is the basic unit for measuring electrical current.A milliamp (mA) is a unit of measurement for an electric current flowing through an electrical conductor and a measure of the rate of flow of electrons. In the international system of units (SI units), electrical current is measured in amperes (or amps), and abbreviated as “A”.Definition: A milliampere (symbol: mA) is a submultiple of the SI base unit of electrical current, the ampere. It is defined as one thousandth of an ampere. History/origin: The milliampere has its origins in the ampere. The prefix “milli” indicates one thousandth of the base unit it precedes, in this case the ampere.

What is mAh in battery?
The capacity of batteries is indicated as XXXX mAh (milliampere/hour). The formula for calculation is as follows: Capacity (milliampere/hour) = discharge (milliampere) x discharging time (hour) E.g. Take a Ni-MH rechargeable battery with a capacity of 2000 milliampere/hour.
What does 20Ah mean on a battery?
General SLA Batteries are usually rated at 20HR, meaning their current over a period of 20 hours. If a battery is rated at 20Ah capacity at 20HR, it means that the battery can discharge 1 Amp per hour over that 20 hour period. A High Rate Battery will typically be rated at 10HR or less.
