These tests below only note my personal ESTIMATED ratings for the batteries I tested 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 property damage, personal injury, or even death. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Testing batteries at their limits is dangerous and should never 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.
Test Results
This is a good performing cell, essentially equal to the Samsung 40T at up to 25A. The Molicel P42A performs a little better but I don’t think you’ll see much difference in actual use.
I can not find a datasheet but Vapcell lists these with a 4000mAh 30A rating. Without a datasheet to confirm the claimed 30A rating I recommend staying under 25A with this cell to reduce voltage sag and extend cell life. Like any Li-Ion round cell not in a protected battery pack, you use it at your own risk.
The two cells I tested delivered 4006mAh and 4016mAh, meeting Vapcell’s 4000mAh rating. That is great consistency and is typical for cells from the major manufacturers.
I do not know who carries these cells but if you cannot find them anywhere Vapcell donated them for testing so you could contact them: 18650 batteries, Vapcell batteries, 18650 Chargers

I want to work for the community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: Battery Mooch is creating battery and device tests | Patreon.
