Battery

Batteries store energy, much like a gas tank stores gas. The word battery is limited to an electrochemical device that converts chemical energy into electricity, by use of a galvanic cell. A galvanic cell is a fairly simple device consisting of two electrodes (an anode and a cathode) and an electrolyte solution. Batteries consist of one or more galvanic cells. As chemicals in the battery change, electrical power is stored or released. Batteries are not 100% efficient. Some energy is lost as heat and chemical reactions when charging and discharging. If you use 1000 watts from a battery, it might take 1200 watts or more to fully recharge it. Slower charging and discharging rates are more effi

​

Ampere (A)

The amount of current flow within a circuit. Measured in Amps.

​

OEM

OEM stands for Original Equipment Manufacturer, referring to the particular maker of the battery. OEM batteries are often referred to as "original" batteries.

​

Volt

A volt is the unit of measure for electrical potential or pressure.

​

Watt

A watt is the unit for measuring electrical power (Watts = Amperes x Volts)
