      26650 Great batteries

      I have been struggling to find a battery of this size that can last in my flashlight. I use my flashlight daily for long hours. after spending about $70 in searching for a decent battery I found these guys. By far better than anything on Amazon and Ebay.

      Have been looking for these batteries for some time now-found these and purchased from this seller and it was a great experience-seller checked backed after I ordered to make sure that I was satisfied with my purchase experience-then checked back once again after delivery--very rarely do you receive customer service like this anymore! Highly recommend this seller! thank you once again!
