Odyssey batteries in RVs

Odyssey batteries are AGM batteries built with thin plates of pure lead, made by EnerSys.

Odyssey batteries are made by EnerSys, a large industrial battery company. They use thin plate pure lead (TPPL) AGM construction and are sold for automotive, marine, powersports and other uses, including dual-purpose batteries that can start engines and handle deep cycling.

In an RV

Odyssey batteries show up as chassis starting batteries in some motorhomes and tow vehicles, and sometimes as house batteries in smaller setups. As with all AGM, use an AGM-compatible charging profile. Odyssey publishes charging guidance, and TPPL batteries generally prefer a proper charge to stay healthy.

Heat

AGMs handle heat better than flooded batteries that are allowed to run low on water, but heat still shortens life. Keep the compartment ventilated where possible.
