Thanks for your comments
Thanks for your comments Brianna, Al, and Carl. Here is how you can extend the life of a Toyota Prius battery: "there are shops around the country that will affordably repair a Prius battery by replacing cells and then properly adjusting the voltages." The story is intended to illustrate that the battery outlasts the typical lifespan of a vehicle, and if they do run into trouble, do not need to be replaced, but can be cost-effectively repaired. Either by a local shop, or in some cases, by the owner. Jesse is a very talented man, but he is not a mechanic. I will make an edit to the story to help clarify the point. Thanks again for your comments.
