so they claim some pretty oversized stats on these batteries. They seem to hold up a little longer than my other rechargeables, so I'll give them that. But be warned, I think they get some of the extra mAh from making the batteries a little bit physically larger. I have some flashlights that these things will absolutely not go into. Just physically too round/large. You'd have to hammer them in, and then you'd never get then out again. So if they work in what you need, they will do a good job. BuSee full review
