Description
The Odyssey Performance Marine Group 31M AGM Battery is a dual-purpose deep cycle and starting battery engineered to deliver exceptional cranking power and long-lasting energy storage for marine and RV applications. Designed to perform like both a sprinter and a long-distance runner, this 12-volt AGM battery provides massive starting power while supporting repeated deep-cycle use.
With 925 cold cranking amps (CCA) and 100Ah capacity, the Odyssey Performance battery is ideal for engine starting, trolling motors, and powering modern onboard electronics. Built with absorbed glass mat (AGM) technology, it offers superior vibration resistance, spill-proof construction, and maintenance-free operation.
Capable of delivering up to 400 cycles at 80% depth of discharge, this battery provides twice the overall power and up to three times the service life of conventional marine batteries. Its dual top terminals (standard post and threaded stud) ensure flexible and secure installation across a wide range of marine and RV systems.
