Designed to change what you can expect from a marine battery

When it comes to replacing a marine battery, boat owners have traditionally had two choices — starting or deep cycle. Often this has meant a compromise because, in reality, most boaters want both — a marine battery that delivers robust starting power when they need it, yet also withstands deep and frequent depths of discharge (DOD) without significant power loss. Unfortunately, no single battery could provide both.

Until now.

Like an athlete that is both a sprinter and a long distance runner, the ODYSSEY Trolling Thunder 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.

Features

• Longer service life: Forget replacing batteries every year. With 3-10 years of service life, ODYSSEY batteries save consumers time, money, and aggravation.
• Longer cycle life: 70% longer cycle life compared to conventional deep cycle batteries — up to 400 cycles at 80% depth of discharge — high stable voltage for longer periods of time.
• Longer shelf life: Can be stored on open circuit (nothing connected to the terminals) without the need for recharging up to 2 years or 12.00V, whichever occurs first.
• Faster recharge: The highest recharge efficiency of any sealed lead battery on the market — capable of 100% recharge in 4 - 6 hours.
• Mounting flexibility: Non-spillable design — can be mounted on any side in any position except inverted. Takes up less space in the boat than competitors.
• Vibration resistance: Design protects against high impact shock and mechanical vibration — a common cause of premature battery failure.
• Extreme temperature tolerant: Operating temperatures from -40°C (-40°F) to 80°C (176ºF) for the 34M-PC1500 and 31M-PC2150. No need to winterize this unit — leave it in the boat!
• Totally maintenance free: No need to add water, ever!
• Improved safety: US Department of Transportation classified as a ‘non-spillable’ battery. No acid spills, no escaping gases. Drycell design with resealable venting system.
• Superior to spirals: Compressed flat plates eliminate wasted space — 15% more plate surface area and up to 40% more reserve capacity than popular "six-pack" AGM batteries.
