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.
Test Results
This Efest is an average performer (which is decent) and performs a little better than the Hohm Life4 at higher power levels, above 15A/45W or so. The Murata VTC6 and Samsung 30Q perform a little better than this Efest.
Its 20A continuous rating seems reasonable so I am rating this cell at 20A. Its 35A “pulse” rating is useless and can be ignored.
The capacity of the four cells I tested was 2878mAh to 2988mAh. None of the cells met their claimed 3000mAh rating, a common game played by the China cell wrappers. Since the cells I have cannot be the lowest capacity ones in the batch I am rating this cell at 2800mAh.
Four cells were bought for the purposes of testing by me.

I want to work for the vaping 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 tests and educating vapers | Patreon.
