Some batteries offer enormous cranking power. Others, deep cycle reserve power. The Unbeatable PC1800-FT ODYSSEY dual purpose battery does both. Even at very low temperatures, the Odyssey PC1800-FT battery has 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.
