Description
Each monobloc is made of 6 cells with the electrolyte held in a glass-mat separator, so there is no water to top up and the battery tolerates tilt. Float charging runs at 13.60–13.80 V and cyclic charging at 14.25–14.60 V, both values given for 25 °C. These setpoints go into a charger with an AGM profile. In a hot compartment the charge voltage has to come down, so connecting the charger battery temperature sensor is worthwhile. A large bank is built by paralleling monoblocs of the same capacity and age, with equal cable lengths to each. For a 24 V network the batteries are wired in series pairs.
How to choose
Pick a size from the 55–260 Ah range by daily consumption and by how many monoblocs fit the compartment. For deep cycling in a large bank the GEL 225 Ah or the 2 V 1,650 Ah cells are more convenient. The Lithium Power Basic at 50–150 Ah fits a similar case, gives more than 2,000 cycles and is lighter, but needs a lithium profile on the charger.

FAQ
What is the float voltage of the 12 V AGM battery?
13.60–13.80 V at 25 °C.
What voltage should a 12 V AGM be charged at in cyclic use?
14.25–14.60 V at 25 °C.
What capacities are available in the AGM 12 V line?
From 55 to 260 Ah, all 12 V monoblocs of 6 cells.
Does a AGM battery need water topping?
No, the electrolyte is absorbed in a glass-mat separator and the battery is maintenance-free. Only the charge setpoints need checking.
How do you build a 24 V bank from 12 V AGM batteries?
Two batteries of equal capacity are wired in series, and for more capacity such pairs are paralleled. The charge setpoints then double.
