I've been searching for information all over, and it's surprisingly hard to find the details. I see that sodium is much better than lead but not as good as lithium, but cheaper and nontoxic, so I went looking for why Pb batteries aren't dead yet and replaced by Na everywhere.

Looks like the alternators will have to be replaced (or can they be reprogrammed?). Any mechanics or engineers here have additional insights?

Also should be applicable to UPS batteries. Anyone building those?

I guess being years ahead of the US in modern tech, including drones with a government made from mostly ENGINEEERS and SCIENTISTS.
