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.

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.

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.

Great batteries, well packaged, genuine.

These came well packaged in an Efest labeled box and and within I find the batteries contained in their own separate plastic battery boxes with lids which will come in very handy.

Quality battery.
