Every once in a while we get questions from our customers asking to define some of the terms that they find on their battery. So here is a short list of some of the more common terms and their definitions.

Volt – This is a measure of electrical potential. The volt is named after Alessandro Volta the “father” of batteries.

Watt – This is the unit for measuring electrical power, i.e., the rate of doing work, in moving electrons by, or against, an electrical potential (Volt). Formula: Watts = Amperes x Volts. This was named after James Watt one of the leaders in developing steam engines in the late 1700’s.

Watt-hour – Not to be confused with a Watt, this is a measure of electrical energy. Simply figured by multiplying Watts x Hours.

Ohm – This is not the sound that monks make in the movies, it is however a measure of the electrical resistance or impedance within an electrical circuit. Named after Georg Ohm the brain behind Ohm’s Law where he realized that there is a proportional difference when voltage is applied across a conductor and the current that goes through it.

Ampere – Commonly shortened to Amp this is the unit of electric current or amount of the electric charge. Amps are named after André-Marie Ampère who is one of discoverers of electromagnetism.

Basically you can look at it somewhat like this; the voltage is how much power you need and the AH or amps is how much gas you have in the tank. Let me know if these help.
