That’s actually an ingenious idea I hadn’t thought about. How much cheaper are these batteries once they’ve been retired? Would this be a viable option for someone running solar at home, and wanting to store the power for later use, or is a home battery still the better option?

Yea, with a car you can't really use them once the range gets low enough

With this, a bunch of batteries can work together for much longer. You also don't need to worry about weight since they're in one place

There’s also something about their peak current being reduced with age, and in this use case, they don’t really need that peak current, so they really can stay useful for a long time in this use case
