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.

Good cost to value ratio
Batteries (4) had a full charge upon arrival, which was quick thanks to Amazon Prime.Pricing was very reasonable for these 21700sized batteries.

Worse than the three year old battery they were bought to replace
Pretty much garbage. Bought these for a battery replacement on a smart doorbell. Original battery used to last around two months and over a few years only lasted 2-3 weeks. Only tried one of these so far, but the charge only lasts 1-2 weeks, literally worse than a three year old battery. Will try one of the others in the pack and edit my review if those work better, but otherwise I'd save avoid these at all costs.
