I have a 05 Prius with 143,000 miles on the clock and the original battery was changed at a little over 100,000 miles, sometime around 2010. I recently did a charge and discharge with the Prolong equipment and Dr.Prius claims there is approximately 57% left to the battery. Obviously we don't drive the car that much but given the amount of time the battery has been in the vehicle, how long would the guess be for it's demise? Also, in 2021 the hybrid battery looked like it was dead and I cleaned the corrosion on the posts and installed a new harness and computer. That was at 131,000 miles and its had a complete charge and discharge twice since that time. I talked to the parts department at the local Toyota dealer and they quoted me $2,500 for a new battery of which I would install myself. Is that the going rate for a new battery?
I've seen prices range from 1600 to 4000. Id call all the dealers within a reasonable driving distance.
Yes, there are about 5-6 dealers within driving distance from my home so I'll shop around for a price. When that time comes I'll just pull the battery and make the swap instead of paying for a core charge.
That's not very feasible, especially for a first-timer. Some parts from the old battery need to be reused on the new battery. To ensure you don't return any parts you will later need, it is better to take the new battery home, swap the parts, and when you're sure you have a working system, you can return the old battery.
Everything here - including the sheetmetal bracketry, plus the module vent hoses. I don't remember everything specifically, because I always pay the core charge. That way there's no stress about forgetting something during the replacement. You get new modules with busbars, clamped and mounted to the base housing, the high current cables, (including the safety fuse disconnect socket) and the HV sense harness to the ecu. Plus some foam seals (@ the HV cables to direct airflow) and nuts for HV connections -48 INCH-pounds please. Posted via the PriusChat mobile app.
Besides what dolj said, I also suggest that you open the shipping case in the dealer's lot (or very close by) and inspect the battery. The first one I picked up had apparently been dropped, with broken plastic on one side. Who knows what sort of damage inside the modules. Unfortunately I didn't see that until the shipping case was opened at home, so we got to put it back in the truck and drive it back. I don't think this situation is at all common, but when it happens, it is a PITA.
OK, yeah it doesn't sound like it would be wise to drop off the original to avoid the core charge. Thanks. And thanks for the tip about opening the box before leaving.
