The Victron Energy 12V 220Ah Gel battery offers best deep cycle durability and overall longer life. The use of high purity materials and lead calcium grids ensure that for both AGM and GEL products have particularly low self-discharge so that they will not go flat during long periods without charge. Both ranges are supplied with M8 drilled, flat copper terminals ensuring best possible connection contact and eliminating the need for battery terminals. The batteries are compliant with both CE and UL specifications in ABS fireproof containers and come with Victron's 2 year world-wide warranty. Features of the 12V 220Ah Gel batterySealed (VRLA) Gel BatteriesHere the electrolyte is immobilized as gel. Gel batteries in general have a longer service life and better cycle capacity than AGM batteries. Low Self-DischargeBecause 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 by 10°C.Victron VRLA batteries can therefore be stored for up to a year without recharging, if kept under cool conditions. Exceptional Deep Discharge RecoveryVictron VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge.Nevertheless repeatedly deep and prolonged discharge has a very negative effect on the service life of all lead acid batteries,Victron batteries are no exception. Battery Discharging CharacteristicsThe rated capacity of Victron AGM and Gel Deep Cycle batteries refers to 20 hour discharge, in other words: a discharge current of 0,05 C.The rated capacity of Victron Tubular Plate Long Life batteries refers to 10 hours discharge.The effective capacity decreases with increasing discharge current. Please note that the capacity reduction will be even faster in case of a constant power load, such as an inverter. Looking to protect the battery against excessive discharge, the BatteryProtect is just what you are after.
