EnerSys has rebranded its existing line of Odyssey batteries as the Odyssey Extreme Series battery line to differentiate between the existing product line and a line of batteries in development. Odyssey Extreme Series batteries are designed for demanding applications. The pulse-hot cranking amps, cold cranking amps, and reserve capacity ratings are higher than those of conventional batteries. All Odyssey Extreme Series batteries are absorbed glass mat batteries and feature thin-plate, pure lead (TPPL) technology. Pure lead plates are thinner and provide more surface area for improved power. TPPL technology enables the batteries to provide reliable starting, lighting, and ignition as well as deep cycling for parasitic loads, such as computers for fuel-injection systems.
