    I just bought a brand new hybrid battery from Toyota for my 2007 Prius and in the process of installing the large orange wire harness onto the battery, I over tightened one of the nuts and sheared off a stud on one of the cells. Would there be any issues installing a single reconditioned cells in place of the damaged unused new cell? Does Toyota sell individual cells new?

    Ouch. Toyota doesn't sell individual modules.

    You could put in a reconditioned module, but unless it is very close to new in performance, it will be the limiting factor in the performance of the whole pack.

    If you haven't bought a good-quality inch-pound torque wrench, it's good to have for this job.

    You will find brand new factory modules at eBay.

    Yes, a torque wrench is a very wise "must have". Pictured tool is what I purchased when I replaced my hybrid pack.

    Damn, you folks torque them? I just replace the terminal plates, and set my Bosch IDH182 impact on the lowest setting and give it one "dugga". I've rebuilt three batteries this way.

    I feel like I might be a heathen.
