The Prius battery is a
The Prius battery is a non-issue.
All the Prius taxi cabs in service in cities like New York, San Francisco, Vancouver, etc. have routinely exceeded 200,000 miles with zero warranty-covered battery problems (i.e. HV batteries that died on their own and not as a result of accidents or user abuse).
Not to mention the battery warranty in the Prius is 150,000 miles / 10 years in the states that have CARB emissions regulations.
Besides, nobody in their right mind would buy a brand-new $2000 HV battery to put in a Prius that already has 100,000+ miles on it. The Prius battery is essentially part of the electric power split device transmission. If you have a regular car which had a transmission failure after 100,000 miles, do you spend thousands to put in a brand-new transmission? Heck no-- You buy a rebuilt transmission for cheap.
Same applies to the Prius-- a good-condition battery salvaged from a Prius that has been totaled in an accident costs $600. And it will give that high-mileage Prius another 4-5 years of good service. No need to spend thousands for a brand-new traction battery.
