Best batteries

These are the best batteries I've bought. We've gotten about 4 years use out of them with our vape and they are finally not holding charge properly.

Best batteries I've ever used.
January 3, 2019
You really can't go wrong with these cells. I've been using them over a year and and there is no noticeable loss in chargeable time. The insulation is starting to peel around the ends due to normal use so I'm looking to replace them with the same batteries. Can't give them a higher recommendation than that!
