Marine Performance Series Batteries

Like an athlete that is both a sprinter and a long distance runner, the ODYSSEY Marine Dual Purpose battery has both massive starting power and amazing deep cycling capability – up to 400 cycles at 80% depth of discharge. With twice the overall power and three times the life of conventional marine batteries, the ODYSSEY battery is ideal for trolling, starting, and for powering the many on-board electronic accessories common in today’s boats and recreational vehicles.

Odyssey batteries deliver impressive starting power, fast recovery and reliable deep cycling capabilities that modern vehicles demand.

How so much power is possible

ODYSSEY Performance Series batteries contain flat plates made of 99% pure lead – not lead alloy, like many conventional batteries. Pure lead plates can be made thinner, so we can fit more of them in the battery. More plates mean more plate surface area, which means more power when you need it.

Packed with more power

Like many popular spiral-wound batteries, ODYSSEY Performance batteries employ dry cell Absorbed Glass Mat (AGM) technology to contain acid, allowing the battery to be installed even on its side. But the densely packed flat plates in an ODYSSEY Performance battery avoid the “dead space” between cylinders in a “six pack” design. The result is 15% more plate surface area — and that translates to more power!
