ODYSSEY® Performance ODP-AGM8D batteries meet the ever-increasing power demands of mass-transit vehicles. They are manufactured with Thin Plate Pure Lead (TPPL) technology that contributes to twice the overall power and three times the life of conventional batteries. Their sealed design results in a virtually maintenance-free battery, non-spillable dry-cell design and the ability to resist extreme vibration to protect against high-impact shock and mechanical vibration that often lead to premature failure. ODYSSEY® Performance ODP-AGM8D batteries are dual-purpose for starting and deep cycling to provide long-lasting power and far less maintenance for a lower Total Cost of Ownership.
