What is the average life for the hybrid batteries used in the Toyota Prius?

Answer 1

I own 2 of them, an 02 & an 04, both bought in there prior years. I have not had any trouble with either one. the 02 has about 45000 miles on it. I also have been on the Prius lists since 02 looking for this same question. What i have found out is that there have not been any battery failures, including a taxi in new york that has over 250000 miles on it. A battery pack consists of individual cells that can be purchased separately. If 1 cell does go bad, you don't have to replace the whole pack. I don't think the battery pack should be any cause for concern.

Life of a Hybrid BatteryI heard in the area of 10 years, and they are ungodly expensive.

They are warrantied for 7 years. <---This statement simply is not true, do some research and you will find out.
