average hybrid battery life
I'm not saying that these batteries will last forever, but the general sense is that they will last for, quote, the lifetime of the vehicle.. Cinda Gobeille had to garage her Toyota Prius when the battery gave out after a healthy life of 10 years and 144,000 miles. The car looks great, she says. But without a new battery, which dealers say will cost up to $4,200, her hybrid simply won't turn on. It could get 50 miles per gallon on a good day, says Ms. Gobeille, a nurse case manager from Woonsocket, R.I. When the battery was dying, it dropped down to probably 35 [m.p.g.]. It's a great little car.
