GEL Deep Cycle 12V/265Ah (M8) - Deep cycle GEL battery, M8 threaded terminals
GEL Deep Cycle 12V/265Ah (M8) is a sealed lead-acid (VRLA) battery with gel-immobilised electrolyte, designed for repeated deep cycling and a 12-year float design life. With 265 Ah it is suited to battery banks in off-grid systems, motorhomes and boats. Lead-calcium grids keep self-discharge below 2% per month at 20 °C.
Main features:
- Voltage and capacity: 12 V, 265 Ah (C20)
- Float design life: 12 years at 20 °C
- Cycle life: 500 at 80% DoD, 750 at 50% DoD
- Cold cranking amps (CCA): 650 A
- Terminals: M8 threaded inserts
- Dimensions and weight: 520 × 268 × 223 mm, 75 kg
VRLA AGM: design life 7-10 years
VRLA GEL: design life 12 years
The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches.
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. 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.
