EnerSys' Odyssey, the extreme battery, is a 12V heavy duty and commercial battery designed to keep up with the continually increasing demands of technology. The Odyssey's reserve power can run on-board accessories with the engine off and without shortening battery life. The extreme battery features a rugged construction, tightly packed with pure lead plates, a nonspillable AGM design that protects against shock and vibration and mounting flexibility. It was designed to quickly recharge, be maintenance free, tolerate extreme temperatures and to lower emissions and gasoline use.
