Not a standard size. Too large.
Customer service has been great.Found that these are too large to fit three devices that take 21700.Can’t use where I need to.

Too wide!
These batteries are too thick and would not fit my device. Now I don’t know what to buy because why the hell wouldn’t all 21700 batteries be the same damn size??? Double As are, triple As are, Ds and Cs are! Makes no sense!
