Lithium metal batteries with diluted high concentration electrolytes

You probably won’t be able to do the job in an hour without a lift, but you _can_ use just ordinary jacks. Certainly every car shop on the planet has the tools to do it; they won’t have to buy anything specialized from Tesla.

One Tesla tool they need —which Tesla released— is diagnostic sw to help ID the bad cell(s), else it would take longer to find a bad cell among ~1,500 of them.

Tesla just replaces whole packs now. They might have a tool to diagnose a bad battery but they don’t replace modules, they only replace entire packs.

As such their next gen pack is a single structural member of the car and likely will not be replaceable at all.

As I understand it, neither of those statements are exactly true.

Tesla replaces battery packs and then sends the old one back to the factory to be refurbished, rather than junked.

As for future designs, a structural battery pack would still be replaceable. The difference is that the battery pack would supply a portion of the strength and rigidity of the frame. That doesn’t mean the car would fall apart if you removed it, however.

That’s true if there are a small number of bad modules that you want to replace, but not really relevant if you’re just going to swap a new battery into an old Tesla.
