GRANKIA FG4-12 valve regulated sealed 12v lead acid battery 4ah is a rechargeable battery that uses lead and sulphuric acid to function. The lead is submerged into the sulphuric acid to allow a controlled chemical reaction.

The 12v lead acid battery is formed by dipping the lead peroxide plate and sponge lead plate in dilute sulfuric acid. An electric current is connecting externally between these plates. In diluted sulfuric acid, the acid molecules split into positive hydrogen ions (H+) and negative sulfate ions (SO4 − −).

AGM lead acid battery in series or in parallel connection

Note:

  • To avoid cycle life shortening, it is recommended not to discharge the battery below 50%.
  • We highly recommend installing the battery upright. DO NOT install the battery upside down.
  • It is recommended to connect batteries with the same type (AGM), same voltage (V), and same capacity (Ah) from the same brand.
