Hi Sharon,
Hi Sharon,
Depending on the model year of your car, a new hybrid battery can cost anywhere from ~$2500 to $4000 to replace. In May of 2019 Toyota wanted $2700 to replace the hybrid battery in my wife's 2005 Gen2 Prius. I decided to rebuild the hybrid battery myself for about $35 and it has been working fine ever since then. It is not something that the average Prius owner can do themselves so I don't recommend that approach unless you are comfortable taking apart a 220+ volt battery and putting it all back together again.
