5 of 5 Excellent Batteries June 13, 2020
Reviewer: Dwight Hull from Huachuca City, AZ United States  
The 21700 batteries I purchased from the 18650 Battery Store are some of the best batteries I have ever owned. Long lasting, durable, and high quality. If you need great batteries for a great price, look no further. The 18650 Battery Store has the right battery for your needs. Highly recommended.

3 of 5 Price was right and the shipping was fast... May 17, 2020
Reviewer: SteveB from Morrow, GA United States  
The above was the good but the thing that bothers me is that the batteries were received with almost zero charge. I've bought lots of batteries over the years and this is the first time I've received batteries with such a low'amount of charge. They did seem to charge up well but I was surprised at the relatively low amount of charge it took to bring them up to full charge. We'll just have to see what their life is like.
