Environment Transportation Hybrid Car Battery Life and Replacement Costs By Christine & Scott Gable Writers Millersville University Christine and Scott Gable are hybrid auto and alternative fuel experts who have brewed their own biodiesel and traveled 125,000 miles on waste vegetable oil. our editorial process Christine & Scott Gable Updated February 28, 2019 fotog / Getty Images Share Twitter Pinterest Email Transportation Automotive Active Aviation Public Transportation It is expensive to replace hybrid batteries—it can cost in the neighborhood of $3,000 for a full hybrid battery replacement. But on the other hand, hybrid batteries have proven themselves to be extremely reliable. And as long as they are not abused and the vehicle charging control system operates effectively, they can be—not unrealistically—expected to last for nearly the life of the vehicle. Manufacturers are providing generous battery warranties (generally about 8-10 years and 80,000 to 100,000 miles), but as with most warranted components, they are designed to last well beyond the coverage period. It would not be unreasonable to expect the life of a battery pack to exceed 150,000 miles. Something to keep in mind: as more hybrids take to the roads, reclaimed batteries from out-of-service (wrecked) cars will become more available at steep discounts.
