Odyssey Extreme Series 12V Marine Battery, Group 31M, 103 Ah • ODX-AGM31M

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.

• Longer service life - 3-10 years of service life to save you time, money, and aggravation
• Longer cycle life - 70% longer cycle life than conventional deep cycle batteries - high stable voltage for longer periods of time.
• Longer shelf life - Can be stored on open circuit (nothing connected to the terminals) without recharging for 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 which can be mounted on any side in any position except inverted.
• 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 45°C (113°F), for models without a metal jacket, and from -40°C (-40°F) to 80°C (176°F) for models with a metal jacket.
• Totally maintenance free - No need to add water, ever! Drycell design with resealable venting system.
• Improved safety - US Department of Transportation classified as a 'non-spillable' battery. No acid spills, no escaping gases.
