Hybrid Battery Packs assist the engine by providing power to maximize the fuel economy for Hybrid vehicles. Dorman’s OE FIX uses new cells in the Hybrid Battery. Our OE FIX repair solution bypasses the need for OEM programming once the Battery is installed on the vehicle. All of Dorman’s Hybrid Battery Packs are plug and play, requiring no flashing or scan tool which optimizes the vehicle’s fuel economy. For a complete repair, harness and battery electronics are included.
