Victron 12V/220Ah AGM Deep Cycle Battery with M8 threaded insert terminals

The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches. VRLA AGM: design life 7-10 years VRLA technology: VRLA stands for Valve Regulated Lead Acid, which means that 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-fibre mat between the plates by capillary action. As explained in our book ‘Energy Unlimited’, AGM batteries are more suitable for short-time delivery of high currents than gel batteries. Low Self-Discharge: 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 i...
