12V Odyssey Extreme G24 Battery - 840A CCA - 76Ah

Some batteries offer enormous cranking power. Others, deep cycle reserve power. Unbeatable Odyssey® Extreme batteries do both. Even at very low temperatures, Odyssey Extreme batteries have the power to provide engine-cranking pulses in excess of 2250 amps for 5 seconds – double to triple that of equally sized conventional batteries. And they can handle 400 charge-discharge cycles to 80% depth of discharge.

How so much power is possible?
Odyssey Extreme batteries are made with flat plates made of 99% pure lead – not lead alloy, like many conventional batteries. Pure lead plates can be made thinner, so more of them can fit in the battery. Additional Odyssey battery plates means more plate surface area. And that means more power – twice as much as conventional batteries.

Packed with more power
Like many popular spiral-wound batteries, Odyssey Extreme 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 Extreme battery make use of the “dead space” between cylinders in competing "six pack" designs.
The result is 15% more plate surface area — and that translates to more power!

This extreme combination of power and performance makes Odyssey batteries perfect for a range of applications, including automotive/LTV, marine, commercial, and powersports.

Why Use Odyssey Batteries
• Better Warranty - Up to 4-year limited full replacement warranty — not pro rata
• 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
• 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
• 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°F (-40°C) to 140°F (60°C) for models without a metal jacket, and from -40°F (-40°C) to 176°F (80°C) for models with a metal jacket
• Virtually Maintenance-Free - Sealed, AGM design never requires watering
• Improved Safety - US Department of Transportation classified as a ‘non-spillable’ battery. No acid spills, no escaping gases
