Some batteries offer enormous cranking power. Others, deep cycle reserve power. The Unbeatable PC2250 ODYSSEY Extreme Series batteries do both. Even at very low temperatures, ODYSSEY Extreme Series 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.
