Odyssey trademark is the property of Enersys and affiliates.

  • Made in the USA. Why it matters:
    • Superior craftmanship; rigorously tested; high-quality parts.
  • Better warranty
    4 Year BCI Sized Engine Starting Applications.
  • Longer service life
    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
    This 12 volt, 100Ah battery 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.
  • 2 Batteries in 1
    The characteristics of two separate batteries are combined in one box. This 12 volt, 100Ah battery can deep cycle (be recharged) as well as provide enormous cranking power.
  • Superior cranking
    The 5 second cranking power of Odyssey batteries is double to triple that of equally sized conventional batteries, even when the temperature is as low as -40°C (-40°F).
  • Mounting flexibility
    Non-spillable design - 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 tolerance
    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.

The Perfect Battery & Battery Store

I ordered two AGM Odyssey Batteries for our Airstream Travel Trailer (Online) on Monday Morning about 8:30 am. A Sales Rep called about 11:00 am to verify the ship to address, and told me I should receive them the next day. By 3:00 pm the following day I was installing them. It just doesn't get any better then that.

I had initially tried to order the batteries from Auto Zone, and authorized dealer, but they didn't have any in their warehouse. I told them I would get them from Battery Mart, and they said, if you do bring the cores in here, and we'll give you $20.00 store credit.

This was a Win Win situation. I really did try to support our local guy first. Next time I need a battery, I'll shop at Battery Mart!

I previously had the Sears version of this product in my boat. It died after 4 years (3 year full warranty). When I went to replace it, Sears had stopped carrying it and so I went direct to the manufacturer.

It starts my boat, charges, just what it should do. It is like $360 delivered versus the Sears branded version at $289. I only gave it one star for the huge markup rather than a product or battery mart issue.
