Toyota Prius Battery

How Long Does a Toyota Prius Battery Last?

Since the release of the Prius in 1999, many car owners considering the hybrid had an important question that kept creeping up in their minds: Just how long would a Prius battery last out on the road? Secondly, how much would the battery system cost to replace if it ever wore out or became damaged in an accident? Now that the Prius has been on the road for over 10 years, many consumers will consider picking up a used version of the Prius as well, and so the question still remains important today.

According to Consumer Repoorts, the numbers look good. They compiled data in 2011 from 36,000 Prius hybrids, and took into account reliability and ownership costs. Both displayed very good numbers. They also hooked up a 2002 Prius with 208,000 miles on the clock to compare to a 2001 Prius that was tested 10 years ago. They found very little differences in fuel economy and acceleration, which suggests the battery systems are really built to last.

If your battery ever needs to be replaced, your first step is to check your car's warranty. Toyota will cover any associated battery costs for the first 100,000 miles of your vehicle ownership, so you can rest easy. Even if your Prius gets long in the tooth, driving well past the battery warranty, the cost to replace the battery isn't that staggering (though not insignificant). The battery system will cost $2,200 to $2,600 to replace from a Toyota Dealership. Alternatively, you can find a low-mileage battery unit from your local salvage yard for roughly $500.
