The Prius traction battery died at $190k miles which was a little disappointing. The Toyota dealership wanted $5,000 for a new one! I found several companies that assembles new batteries from individual modules and supposedly "recondition" them, even providing limited warranties.
Figuring I had to take the battery out anyway, I pulled it by myself and disassembled it in the garage. I simply measured the voltages across each of the 28 modules and found 3 that were considerably lower than the others. I ordered 3 on Amazon for $30 each, put it all back together. And it worked! .....for about $6,000 miles.
So I bit the bullet and ordered a "reconditioned" unit for $1350 plus shipping, supposedly a Gen 3 pack to replace my Gen 2 pack (i.e., newer battery). It had a 12-month, 12,000 mile warranty (same as Toyota for $5k battery!). It lasted about 30,000 miles and two years, instead of the promised 3 to 4 years.
I've done enough research to understand that there is no good way to match up 28 modules, it's pretty much whack-a-mole. If I did it over again, I'd buy a new battery from newpriusbatteries.com. Anyway, the car has $230k on it, bad struts, hail damage, etc. It's time to put it to bed.
The car has been a real trooper, it's saved us many thousands of dollars over the years in fuel costs and maintenance. I just now replaced the front brake pads the first time at 225,000 miles. If the whole car was in better shape I'd spring for the battery. Takes about 4 hours to change it.
