What causes hybrid batteries to degrade and fail? Eventually all batteries will fail. Hybrid Electric Vehicle (HEV) NiMh batteries have a life cycle. When the hybrid battery does not last as long as the rest of the vehicle, replacing it costs several thousand dollars and creates hazardous environmental waste. Delaying battery failure beyond the service life of the vehicle will reduce the negative environmental impact of hybrid vehicle ownership and save the vehicle owner thousands of dollars. There are three major phases of hybrid battery lifespan. Usable capacity and performance decreasing as the battery ages: Typically begins: Typically ends: Phase 1: Healthy hybrid battery New Vehicle 3-6 years Phase 2: Weakened/weakening hybrid battery 3-6 years 5-11 years Phase 3: "Failed" hybrid battery (DTC code present) 5-11 years Each hybrid battery 'pack' is comprised of many indi ... read more
