What does VRLA mean?

Valve Regulated Lead Acid (VRLA) battery, is a type of low maintenance sealed lead-acid battery. VRLA battery limit inflow and outflow of gas to the cell – thus the term “valve regulated”. VRLA features a uniquely efficient gas recombination design where oxygen and hydrogen that evolves from the active materials are converted back to water by electrochemical recombination, eliminating the need for watering.
