Toyota Prius Traction Batteries

flytyer07

I'm gonna buy a Prius soon....I hear batteries can last from 100.000 miles to 200.000 miles is that true and what is the cost to replace them?

There's really nothing to suggest that the batteries will fail at 200,000. Generally speaking, Toyota feels that the batteries should last the life of the car---which for most cars is around 225,000. But they may last longer! These battery packs are among the least-replaced items on a Prius.

Replacement costs have come down, but they are still pricey---something like $2500 plus labor.

Used ones are sometimes offered on eBay (from wrecked vehicles).

If you are in a state that conforms to California emissions standards, you should have a warranty to 150,000 miles. (or 100K in states without those laws).

I keep hearing horror stories of hybrid battery failure and replacement costs. I still don't know if these stories are specific to Prius or for other hybrid makes/models. Has anyone had to replace a Prius hybrid battery within 10 years of purchase? If so, how many miles did it have?
