General Purpose Batteries

A battery is a chemical device that stores electrical energy and converts it into direct current (DC). All batteries can be divided into two categories: primary (non-rechargeable) and secondary (rechargeable). Primary batteries are used once and discarded after discharge. Secondary batteries can be electrically recharged after being discharged. Secondary batteries can be used as energy storage devices that are connected and charged by  a main energy source and then used to supply energy when needed. They can also be used as a primary battery, which can be recharged by a charging mechanism when almost fully discharged.

The most commonly used rechargeable batteries are lead-acid batteries. The two types of lead-acid batteries are referred to as flooded and sealed. Flooded batteries are widely used in the automotive industry and are known as SLI (Starting, Lighting and Ignition) batteries. Sealed batteries are commonly known as VRLA (Valve Regulated Lead Acid) and SLA (Sealed Lead Acid) and are used in energy storage, emergency lighting systems, emergency power, communication systems and electric cars.

General purpose batteries are VRLA batteries and have a capacity of 4V, 6V and 12V. The life of the battery as well as the amp hours, life cycles and depth of discharge will vary depending on the battery selected and under what conditions it will be used.
