4 Pack 18650 Rechargeable Battery 4000mAh with Batteries Charger for Vehicles Toys Headlamps Flashlight

On Amazon I asked what type of battery to use for my desk fan. Which I did buy from amazon. This is the battery that they said to use and it barely fits. It's a hair too long. So the positive side of battery doesn't hit where it's supposed to but right next to it so I do get a connection. Curious if other people have had this problem using this battery with a different product. I am going to keep them because I'm tired of returning things to Amazon. Wondering if I shouldn't start shopping locally. Too many returns these days.

I was very disappointed when I opened the package and saw it only came with a two port charger, the batteries seem great though.

I wanted an extra bright head lightThese work and are Great

Came quickly, as described. Excellent cust. Serv. Had an issue with the charger.They promptly helped me to identify and had a replacement within the week. Would purchase again.

works great

Good quality product. fast free shipping, and a good price.

After looking in multiple places I finally found the right batteries for my camera. They are very long lasting and easy to install and the charger is very fast.

Battery capacity was far lower than the 4000mah listed on the battery. My bike lights fail after a single ride, no better that my original 1300mah battery. The charger worked fine, but was only a 2 position charger and not the 4 position shown in the photo. I'm waiting for approval to return these. They offered to send more batteries, but that doesn't help the problem if they're capacity is no better.
