After I ordered a pair of these Vander "4200mah" 18650 cells to check out for low current use, one showed up DOA. A replacement was sent and I was able to test. One battery apparently developed an internal short and welded itself to the included charger. That battery is now leaking and corroding at a fairly rapid rate. It is being stored in a fireproof container in order to further monitor it's downward spiral. After charging the remaining cell, using it to cutoff voltage and recharging on a smart charger (cycle repeated 5 times for accuracy, it is obvious that these cells are rated well beyond their actual capacity. The most the remaining cell will accept in a charge is 877mah. Hardly approaching it's 4200mah rating. These are not advertised as high discharge, which I would never use them as such....but they are hardly safe for low discharge either. I would recommend steering very clear of these batteries.

I only use manufacturer branded batts for vaping that I buy from suppliers I trust to not sell counterfeits. Samsung, Sony, LG or Panasonic. AW is not a manufacturer, but I also trust them. I buy chargers the same way.

These Vanders are a good example of how things can go really wrong with an unknown battery. Thanks for posting this Orbital-Lexicon.

Whenever I buy an electronic device that includes batteries 9 out of 10 times they are some odd ball crap. I always chuck em and grab Duracells. Now that I vape, it's Sony, Lg, Samsung, and certain Efest. Nothing else.
I'm glad you questioned your purchase and tested them first. Good move.

Well, with the right adapter you might technically be able to shove a AA cell you bought at Harbor Freight for $5 in a 24-pack into a mod...good looking out, @Orbital-Lexicon - another timely reminder to stay away from mystery batteries.

Yeah, I actually bought these to see how they would work in flashlights that are stored for long periods of time. #1 I wanted them to have a low self discharge and #2 I wanted them to have a high capacity. This battery fails at both....miserably. I guess their are no quality budget 18650's.
