Well worth the money!
February 15, 2022
I purchased several of these batteries as backups for my other no name flashlights I stage throughout my home. Seems you can't go 10 feet in my house without being within reach of a light. These work great in all my lights that take 18650s. However being "Button Top" batteries they may not fit all items that take 18650s so be aware of that. I have found that I need to order some of these that are "Flat tops" to fit other items. All my flashlights have springs inside which allow you the extra space for button tops. I will be ordering some of these in flat top for other things with a tighter fit. So far these have been some of the best 18650 batteries I have used. Well worth the money.

I like them,,,
January 17, 2022
The batteries arrived as described, packaged well, and in a timely manner. They work well in my different headlamps and an IR emitter.

I recently purchased a night vision scope camera and needed batteries for it. The manual that came with the camera stated to only use button top batteries, so i ordered these. When i got the batteries I charged them then went to put them in the battery compartment, they did not fit. I contacted customer service and i was told that there is different lengths for the 18650 batteries.

This was my mistake for not researching enough about the batteries and include the story in this review to help others. The difference in length is around .100, so it can be significant depending on the battery compartment.

I will be purchasing again from Battery Junction, they seem to be s good company to deal with.

Consistent quality

I chose Nitecore brand over others as I've found they are consistently good quality. I bought 2 18650's, and they both show about the same drop in percent used when I recharge them.
