Purchased 3 double packs (6 total). I’ve used each of them in a vaping device at least once. The efest website […] says this battery is ‘perfect for vaping devices’ and indeed they work great. My only quibble is that they claim to be 3500mAh 20A but they don’t last any longer than the 3000mAh 35A Efest batteries which I’ve also got. The authenticity scratch codes check out fine.

Very average 18650s

I’ve only had these Efest for just under a month, and they are beginning to loose their charge quicker each day. I’m led to believe that Efest are rewrapped batteries from other manufacturers, so there is no guarantee that any 2 batteries will be the same quality. I may split the batteries and put them in single 18650 mods.

While some Efest batteries are truly high-quality cells, the risk just isn’t worth it. Just buy the original LG or Samsung 18650

Efest is a notorious rewrapper—which isn’t necessarily a bad thing. Because many of their products are rewrapped cells from Sony, Samsung, and LG.

3 or 4 days of vape

These are certainly the longest lasting batteries I’ve bought so far. Although, the plastic coating does come off after a short time of putting the in and out of a charger. I could get a good 3 or 4 days out of them, vaping at about 40W.

Genuine product, long lasting.

These batteries are great! Among all the counterfeits out there and battery safety at an all time priority, these batteries are the real thing. I checked mine against their website and all is good. You can trust this vendor. I use these in my 2 x 18650 mod and they last me a full day and a half of chain vaping at 100 watts. I only bought more as I scrap batteries every 6 months to maintain battery safety. No loss of charge in that time. They come with a carry case too 🙂

last twice as long as smaller alternatives

These last twice as long as the 2600 mah batteries that my cuboid came with. I get around 4 days use out of them. I’ve owned these for a couple of months now. If you like longevity, don’t bother with the smaller batteries and go for these.

Excellent batteries
