Working Great!
These work great so far. Bought them for my flashlights and all seems good.

Overrated and overpriced, not suitable for high drain
NOT 5000mAh batteries. Tested continuous discharge at 20.1A @ 90W, which is below safe discharge for high drain devices. Is probably fine for mid/low drain.

I should have been ordered these
If I could, I would have left a 6 star rating. These batteries are great! Long lasting and I’m a proud customer 👌🏾

Not NiMH, assume they are Li at your own risk
If I didn’t get these for free to test, I would never buy these. They are alleged to be 21700 cells which are Lithium Ion batteries, but nowhere on the batteries or in the Amazon ad does it say that these are Li-ion, in fact in the ad it calls them NiMH. I believe the CE and RoHS certifications (printed on the battery) would stipulate having the type of battery clearly printed on each commercially available battery, these do not. They came with minimal charge and needed a long charge time to reach a 4.2v no load voltage. According to the Amazon ad, these are fully protected, but again no mention of being protected on the battery itself. There was plenty of room on the battery to print out five different DO NOT warnings and as dangerous as Li batteries can be if mishandled, these do not inspire much confidence.

Nowhere close to 5,000mAh
Absolutely not 5,000mAh. I have name brand 21700s from LG and doing a side by side drain test, all 4 of these quit wayyyyy sooner than my LGs that are also rated at 5,000mAhThese are closer to 3-3,500 mAhReally getting sick and tired of all these misleading Chinese products with false claims. There's no honesty or integrity anymore.
