2005 Prius Rebuild or Replace Battery

I plan on it. I couldn't have done this without the help I got here and I'm just so pleased it worked. I hope the thread itself helps someone else with their questions.

It went about 150 miles today and no error codes. I'm feeling like we could go ahead and put the back end back together or should we wait a week or so? Since we used a set of donor cells rather than just swap out the single bad cell, and apparently everything was connected correctly, we should be good.

 

The initial straight up lift to get it out and over far enough to the trunk edge for two people to carry it was difficult (his back was sore for a few days) so we wanted to approach the reinstall more carefully. We carried it to the car and put it on the spare tire together, each holding a short end. Then I climbed in the back seat/trunk area and helped lift on the long sides and held connections back. It worked fairly well.

 

The new-to-us pack has been in for 5 months now and we've driven another 3000 miles or so and I'm happy to report that all is well.

 

We drove it with that battery until July 2022 when it started to have engine problems (not maintaining compression) possibly related to a deer collision. We drove it about 30,000 miles with the donor battery.
