Cool might be the type that some call "semi tip" kindof between flat and full nip.
Was just going by what W9, the maker, sugested. That to make batt-to-batt with "most" flattops required over tightening of spring witch would kill "hot spring" safty feature.
Again boils down to my gripe of lack of standards on these things. Suposedly there are flat and niptip batts. However looking at diff batts I've seen a lot of odd ones, like a "flat top" that looked like a wide niptip, and a "niptip" that appeared to be a flattop with a blob of sodder in middle of +side. Grrr.
I shudder to say this. But as far as battery standards go, I wouldn't mind a lil gov intervention here. UL labs perhaps would be great.
