The Prius has a normal automotive battery that is mounted in the trunk . If it is dead you have to jump the car , the hybrid battery pack is also in the rear of the car . I have read that it is a group of lithium batteries and they rarely all fail , there are places that "rebuild" the hybrid packs by testing and replacing only the failed individual cells, for much less[$1200] than a replacement from Toyota [$2400] .Many first gen. Prius's are still running around on original batteries . All of the rebuilders and the dealer exchange the whole packs [in under 2 hours] .When a certain number of cells in the pack fail the car uses its gas engine only . Here is a good explanation of what happens when the end comes http://www.edmunds.com/fuel-economy/...batteries.html . I have sold a number of Toyotas over the years they are reliable and long lasting . My Duramax gets better mileage than my Saab with the LS2 gas motor . My dad bought a diesel Rabbit new in "82" it was a gutless turd but got over 50mpg and he loved it , it was still running well @350k when I refused to fix the rust any more . I sold the motor to an Amish family to run a refrigeration unit on their dairy farm .
Oh and their will be no political stickers on the back of the wife's Prius .
