2 Pcs Battery for 3.7V 3400mAh Flat Top Battery for Flashlight, Camera, Small Fan, Sound Equipment.

I used them for my flashlight during work. Very useful and last all day. Also the box is very useful to keep batteries together so you don't loose them .

Battery life has been good. Quick delivery and great customer service.

Awesome product I use for a ECig works perfect! Great price as well!

Doesn't hold charge for long. 1 hour most.

I ordered these 18650 batteries due to all its 4- and 5-star reviews. I use the batteries in a vape mod and I needed a couple extra batteries as backups.When I first opened the package, there was a small card that read “HOW TO RECEIVE A GIFT FOR FREE.” It asked me to send the supplier an email with my order number and I would get the gift they prepared for me. I emailed them the info. They replied to the email asking me to write a 4- or 5-star Amazon review and email them a copy of it to receive the gift. It also stated as a requirement for the free gift, “please do not mention it (the gift) in the review.”Most 18650 Li-Ion battery brands I own last most of the day in my mods, even the cheaper batteries. After fully charging these new batteries, I was lucky to have them last a single hour. If you use them for something other than vape mods, they may last longer and be okay… I don’t know. However, in a vape mod, they're terrible. My conscience will not allow me to lie to you for a “free gift”, so I refused the gift and returned the batteries to the vendor for credit. I added one star to this review because all the batteries DID work for at least an hour.

Really like this product. Great quality

I ordered these batteries to see if they would be a good replacement for some old 2500 mAh, 20A high drain batteries that are nearing end of life. Initially, they worked quite well in my box mod. About 30 days in, I noticed they were starting to run out of charge faster than when I got them. I'm a little past 60 days of using them and my year-old high drain batteries outlast them in my box mod.If you aren't using them in devices that need/want high drain batteries, they're probably a decent option. I have other devices that use 18650 batteries and will update this review if perform well in them.

Great price. Works great
