ODYSSEY Batteries by EnerSys provide up to 70 percent more starting power at low temperatures, making it ideal for heavy-duty, deep cycle applications such as over the road trucks, buses, construction equipment, mining equipment and refrigerated trailers. ODYSSEY batteries last up to 10 years in engine-start operation versus 2-3 years for similar batteries. The pure-lead, thin plate technology provides greater cranking power, especially effective at cold temperatures.
