The Chevrolet Volt’s battery, on average, lasts anywhere from 6 to 10 years, and the automaker offers free replacement per its limited warranty coverage (8 years or 100,000 miles). However, outside of Chevrolet’s warranty or in the case of pre-owned units, the cost to replace the Volt’s battery can vary by a huge margin depending upon model year and service location.

Based on the battery’s health (whether it is a new or repurposed unit), Volt owners can expect to pay anywhere between $3,400 and $34,000. Another cost consideration is battery generation, as the Gen 2 Volt battery pack (24 and 32-cell design) offers a usable capacity boost of 25% and a 9% increase in power over the Gen 1 pack (18 and 36-cell design).

Volt owners should consider getting the battery replaced after every 100,000 miles and be on the lookout for signs of an impending replacement like degrading charge retention. At the end of the day, though, it might not be worth paying the full amount of a new battery replacement when the same amount can be put toward the cost of another EV such as the Tesla Model 3.
