2 Packs 3.7V 18650 Flat top Battery 18650 Rechargeable Batteries for Headlamp, LED Flashlight, Electronic Devices etc (Blue)

I bought these to replace the batteries in my flashlight. They are of good quality, and I was satisfied with my purchase.

Works great

I used them as a replacement for my Floodlight and seems to work as expected.

After many negative comments, So far, so good. I'm using them (1 at a time) for a Miniature toy MP3 player.

Product description stated it was 2000 mAh and even the box that it came in stated 2000 mAh. As you can see in the highlighted area on the battery it was actually 3200 mAh which did not fit the flashlight as it was the wrong size.

I have a 'Smok' brand e-cigarette and it runs on a single 3.7-volt battery. I had two batteries and would switch them out every 12 hours. One of the batteries would go from 100% down to 49% after just a few hours, and the other began to do the same, so: they were not holding a charge, because my use did not increase.These new batteries have much longer battery life. I'm 5 hours into a fresh battery and it's at 96%. The old one would have been down to 60% or less in the same amount of time. And, these batteries are a pretty blue color! They also fit my current battery charger.

We fix battery very work good 👍🏼

It charged up properly like the old one and seems to hold a charge when you really use the cordless drill mine came with. It will be the same and save me from buying a new cordless drill/driver.
