I’ll soon be looking to replace our battery bank which is 3 x 200ah Victron AGM batteries. The current batteries are about 10 years old and for the last 3 1/2 years we’ve been off grid. Our charging regime consists of a built in 9kva generator, 300w solar and 140amp engine mounted alternator. The inverter/charger is a Victron multiplus 3000/120. The inverter is on 24/7 as it powers a 240v AAA rated fridge and a diesel fired range which provides cooking, heating and hot water.
I’m more than happy with how the Victron batteries have performed and would be happy to replace like for like. However the Gel version are slightly more expensive and according to the Victron figures would give a longer service life. Could anyone tell me which is likely to be more suitable given my circumstances?
