For the 2009 I had - https://parts.toyota.com/p/Toyota__/...951047031.html
$1995 or about the price of a remanufactured transmission and way easier to install. |
I took a 6-cell NiMH charger, charged up each module. I had a discharge meter and large rehostat and dischared and recorded all capacities. Took out the bad module and the two with the worse capacities. Replaced them with three Gen 3 modules from eBay (this is a 2006 Gen 2 I'm working on). I rearanged the modules putting the best where the previous modules had degraded the worse (the middle) and put the worse where they had degraded the least (the edges). Then I wired all the modules in parallel and charged them back up to the same voltage. Then put back together and put in the Prius.
$1995 for a hybrid battery that'll last another 15 years sounds good to me. But at $700 per kWh for an EV battery, a large 80 or 90 or 100 kWh battery sounds expensive to replace.
