Not bad so far!

Posted by Josh Downie on Aug 9th 2026

So far it's been a good battery. Time will tell.
Great Vendor!

Ok so as for the batteries personally I cant ever tell the difference they either take a charge and last or they don't. Sorry I know people rave about bigger hits etc?!? As for Central Vapors they are great vendors who will go out of their way to make sure you are satisfied. Example one of these batteries were dead on arrival, I emailed they got right back to me asked would I like a replacement sent (nc) or credit. Cant ask for more than that. Prices are competitive, shipping is within comp and stuff always gets here. Thanks Central Vapors!

Considering that I vape at 80 watts they last a good long time for a single battery.

These batteries are rewrapped. Element Vape has the real Samsung for 1 dollar more. And faster to your door...!!! Q
To big for my vape without peeking the wrapper off

Posted by Stephen H on Dec 14th 2024

This battery is slightly bigger around than the others i have and it got stuck partway in my mod. i had to peel off the wrapper to use it. Battery life is exactly what i was expecting though.
Great
