The range of gel models offers the best deep cycle durability and an overall longer service life. The use of high purity materials and lead calcium grids ensures that both AGM and gel products have a particularly low self-discharge. This prevents them from discharging during extended periods when they are not being charged. Both ranges are supplied with M8 copper cable lug connections. This ensures the best possible connection contact and no battery terminals are required. The batteries fulfil both CE and UL requirements in ABS fireproof containers and are guaranteed by Victron for 2 years worldwide.
