VRLA (Valve Regulated Lead-Acid) Battery

Valve Regulated Lead-Acid (VRLA) batteries are rechargeable batteries created to be maintenance-free due to their sealed construction. These valves used sealed batteries to prevent electrolyte leakage and were designed for valve regulation. This battery technology uses fiberglass separators saturated with electrolytes, making the battery maintenance free from leaks. The key feature of VRLA batteries lies in their valve-regulated design, where a one-way pressure-relief valve allows extra gas to escape during charging and discharging, securing the battery remains sealed and safe.
