"these work great for what ever needs a 3v micro lithium battery, i replaced the battery in my gbc games and other things like my watch and now they work like new. gets the job done.

"good bats last forever i only ordered one of these and it came with like 10 idk what happened but hey i'm good with that lol but if buy a red dot you have to get alot of these 5 out of 5

"Only 2 or 3 of the 5 batteries worked. Tried in 2 different sights to confirm. Don't know what the issue is but it's most likely some quality control bs.

"DOA. Out of the 5 batteries I received, only 2 worked, put them in multiple sights both ways they'd fit and nothing worked.
