Unbeatable ODYSSEY Extreme Series batteries offers enormous cranking power and deep cycle reserve power. Even at very low temperatures, ODYSSEY Extreme Series batteries have the power to provide engine-cranking pulses in excess of 2250 Ampere for 5 Seconds double to triple that of equally sized conventional batteries. And they can handle 400 charge-discharge cycles to 80 Percent depth of discharge. ODYSSEY Extreme Series batteries are made with flat plates made of 99.99 Percent pure lead not lead alloy. ODYSSEY Extreme Series 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 Series battery avoid the dead space between cylinders in a six pack design. The result is 15 Percent more plate surface area and that translates to more power!
