For vehicles that call for a Group 27 marine battery, the Odyssey ODP-AGM27M (ELT-AGM27M) brings Performance series AGM power in a sealed case. It is part of the Odyssey Performance series and uses pure lead plate AGM construction. The M designates the marine variant and it carries both stud and SAE terminals.
Odyssey positions the Performance series as delivering Extreme-series reliability and deep-cycle capability for the higher accessory loads of modern vehicles, without the highest CCA and reserve capacity of the Extreme line. The operating range is -40F to 140F. Odyssey lists a stud-and-SAE terminal arrangement for this marine version.
Odyssey rates it at 1500 pulse hot cranking amps for 5 seconds, 182 minutes of reserve capacity, with 85Ah at 20 hr (79Ah at 10 hr). It measures 12.5 x 6.8 x 8.8 in and weighs about 59.7 lb. Order the Odyssey ODP-AGM27M from Track Ready Products and put dependable AGM power under your hood, in your trunk or on your trailer.
Disconnect the negative cable first, then positive. Remove the hold-down, lift the old battery out, and set the Odyssey in with its posts pointing the same way as the original.
Charge it with an AGM-compatible charger. A weak charger that never reaches full charge shortens battery life.
Odyssey's warranty terms call for trickle chargers that hold 13.5 to 13.8V and alternators that deliver 14.0 to 14.7V at the terminals, so check your charging system when you swap.
