These tests below only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a physically and electrically protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition. Use of any of these batteries is AT YOUR OWN RISK.
Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Bottom Line
Vapcell has two versions of this cell. The 9A-rated version is the newer one but the older 10A-rated version can still purchased since everyone has not sold out their stock of the older cell yet.
These Vapcells look the same, and perform almost the same, as the good performing YDL 18350D. The average performance for these Vapcells is not quite as good as the average performance of the 10A-rated YDL cells so I am giving this cell a 9A continuous current rating. They all run at about the same temperature. It’s the differences in voltage sag that affects their current rating.
To extend cell life, minimize voltage sag, and increase your safety margin, I recommend staying at 7A-9A or under for these Vapcells. That’s about 20W-27W per cell. This is a good performing 18350 but all 18350’s are a poor choice for anything above low power levels.
The two 9A-rated cells I tested delivered 1042mAh and 1054mAh. The two 10A-rated cells I tested delivered 1013mAh and 1053mAh. This is decent consistency but they do not meet Vapcell’s 1100mAh rating. I am rating this cell at 1000mAh.
Like all 18350’s I’ve tested the cell-to-cell performance consistency for these Vapcells is not good. There’s not a huge difference between cells but you might notice it if you have one of the better ones and one of the worst ones.
Two cells were donated for the purposes of testing by Vapcell and two were purchased by me.

Performance Specs
DC Internal Resistance = 40.8mOhms (milliohms) average for the two cells.
Total energy delivered down to 3.2V at 10A continuous = 0.9Wh to 1.3Wh for four cells.
I want to work for the vaping community full time!
