3 of 5 INITIAL CHARGING ISSUES May 30, 2020
Reviewer: Stuart McKenney from New Britain, CT United States  
I HAD A SLIGHT ISSUE WITH MY 21700 BATTERY'S INITIAL CHARGE NOT BEING COMPLETE BY THIS CHARGER, BUT ALL OTHER CHARGES HAVE BEEN GOOD MAYBE I PULLED IT OFF THE CHARGER TOO SOON.

I received my 18650 batteries and battery charger in a prompt and professional manner.  I will 100% order from this site again and I have also highly recommended it to my family and friends as well.  Thank you for a great experience.  I rate the 18650 battery store a 10 out of 10!  The battery charger works very good and I have had no problems or complaints about it!
