You are correct the prius
You are correct the prius nickel metal hydride batteries last 100k-175k very rare they make it too 200k my prius hybrid battery failed at 147k. I had an option to buy a rebuilt battery as changing out cells imo is not a good idea. I bought a greentec hybrid battery with brand new cells for 1570$ including tax and installation. When one cell goes bad the others start failing too, Not worth the headache and worth the investment because my 2009 generation 2 prius is in great condition and I get average 47-53 mpg. Here is too another flawless 147k ;-)
