everything I've ever read about battery chemistry says that going all the way to 0% is bad for the cells

Just one more thing… A mostly just for fun reminder of when it was recommended to frequently/often perform a full charge cycle because it actually did have a notable benefit.

That was also when laptop batteries were NiCad instead of Lithium Ion, so both the chemistry and physical construction of laptop batteries was different.
