Odyssey Group 34M Extreme Battery

ODYSSEY Marine batteries outperform spiral-wound

Compared to spiral-wound batteries of equal size, ODYSSEY Marine batteries pack 15% more plate surface area into the case. Avoiding the “dead space” between cylinders in “sixpack” designs means ODYSSEY Marine batteries deliver more power and reserve capacity.

Boat owners have traditionally had to make a choice between starting power or deep cycle power when replacing a marine battery. But most boaters want both — a marine battery that delivers robust starting power when you need it, yet also withstands deep and frequent depths of discharge (DOD) without significant power loss. Now you can have it all.

ODYSSEY Marine Batteries have both massive starting power and amazing deep cycling capability. They're ideal for trolling, starting, and for powering the many on-board electronic accessories common in today’s boats and recreational vehicles.

ODYSSEY Marine batteries are available in two ranges, depending on your power needs. ODYSSEY Performance Series Marine Dual Purpose batteries deliver more overall power and longer service life than conventional batteries, while ODYSSEY Extreme Series Marine Dual Purpose batteries deliver twice the overall power and three times the life of conventional batteries.
