The GEL model range 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.

VRLA GEL design life: 12 years

Victron World Wide Warranty: 2 years

Features:

• 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) Gel Batteries Here the electrolyte is immobilized as gel. Gel batteries in general have a longer service life and better cycle capacity than AGM batteries.
• Low Self-Discharge - 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 Recovery - Victron 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. 
• Compliant with both CE and UL specifications in ABS fireproof containers and come with Victron's 2 year world-wide warranty.
