The Battery Warehouse

The Battery Warehouse Ltd is Lincolnshire & East Yorkshire's premier supplier of batteries & charging appliances. Batteries are made up of 2V cells to produce 6V and 12V batteries. Each cell, in a charged state, is made up of electrodes of Lead (Pb) and Lead Dioxide (PbO2) in and electrolyte of Sulphuric Acid (H2SO4). In a discharged state, both electrodes turn into Lead Sulfate and the electrolyte becomes primarily water. This process is completely reversible when the battery is recharged. In recent times there have been advances in battery technology and VRLA batteries have become very popular.

VRLA stands for valve regulated lead-acid and is the designation for low maintenance lead acid batteries, also called recombinant batteries. These batteries are often called sealed lead-acid batteries, but this term is misleading. A sealed battery would be a safety hazard due to overpressure risks when overcharged and there is always a safety valve present, hence the name valve-regulated.
