Flooded Cars?..

I read somewhere that Tesla re-use 2nd hand car battery packs in their domestic battery storage system.

Lithium ion batteries do not contain elemental lithium

It's a lithium salt, and they are sealed

I didn't say it was. The comment was to waylay the uninformed comment re the 'school boy' reaction of lithium and water.

Clearly it wasn't clear enough for you and others.

That aside, the Lithium Ions, present in the various chemicals depending on the chemistry of the particular battery, can be an issue.

Still, you are free to ignore such things and treat Lithium batteries as you please.

I do and have been for nearly 20 years

Water has never been an issue in the 100 or so packs that have pased through my hads

Copart.

And then bought up by a scrap dealer either as a fixer-upper or to part out.

Plenty of Water/Flood showing up here:

Actually, you did. It was in the sentence you snipped:

"While I?m aware Lithium and water isn?t a good mix, I?d have thought if the battery was flooded and anything bad was going to happen it would have happened before anyone had a chance to drain it."

I'm not sure you understand what you write.

If the above represents your knowledge of EV batteries, I suggest you don't buy a car fitted with them.

Your inability to comprehend simple statements is getting worse.

I suggest you refrain from making yourself look stupid.

Heavy night, was it? Take more water with it.
