Victron Energy Gel 90AH/12V solar battery.
The GEL range offers the best deep cycle durability and longest life. Due to the use of high purity materials and lead-calcium grids, AGM and GEL batteries have a very low self-discharge, allowing long storage periods without charging. Both ranges have flat copper terminals with M8 bolts, which ensure the best possible contact and eliminate the need for battery terminals. The batteries are CE and UL compliant and their containers are made of fire-resistant ABS, and come with Victron Energy's two-year warranty with worldwide coverage.
