I think I need to replace a few cells for my Prius 2009 Prius 2 model... My question is, I don't want to use cells from same or older model cars, I'd rather use a late doner, so what are the latest model cars that uses same cells exactly in Prius 2? Someone told me Lexus, Camry, Prius C, and other car models use same battery cells as well... Thanks guys
The cells from a new or near new battery would be great, but they would be so much better that I don't know how you would match them to the old ones in your battery that haven't failed yet, but soon will. If you can get a NiMH battery from a Gen 4 (That would be a trim 2 until recently when they released the AWDe Prius. As of now, it's the only one with NiMH.), get them all and use them all. Also, any battery from a Gen 3 will work as a donor. But replace them as a set unless you like to create extra work for yourself.
+1. The key thing to which to pay close attention is to ensure the modules in the donor pack are NiMH and not Li-Ion.
