VRLA stands for Valve Regulated Lead Acid, which means the batteries are sealed. Gas will escape through the safety valves only in case of overcharging or cell failure. VRLA batteries are maintenance free for life.
Sealed (VRLA) AGM Batteries
AGM stands for Absorbent Glass Mat. In these batteries, the electrolyte is absorbed into a glass-fiber mat between the plates by capillary action. As explained in our book ‘Energy Unlimited’, AGM batteries are more suitable for short-time delivery of very high currents (engine starting) than gel batteries.
Because of the use of lead calcium grids and high purity materials, Victron VRLA batteries can be stored during long periods of time without recharge. The rate of self-discharge is less than 2% per month at 20°C. The self-discharge doubles for every increase in temperature with 10°C. Victron VRLA batteries can, therefore, be stored for up to a year without recharging, if kept under cool conditions.
Exceptional Deep Discharge Recovery
Victron VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge. It should, however, be stressed that repetitive deep discharge and prolonged discharge have a very negative influence on the service life of all lead-acid batteries, Victron batteries are no exception.
