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
EVE is one of the large, established cell manufacturers in China (EVE). This is a moderate-capacity cell for low power applications and where lower cost could be a priority over performance, e.g., powerbanks, powerwalls, and larger PEV battery packs.
This cell is rated by EVE at 7.5A but I recommend staying below 5A to reduce the voltage sag and help to extend cell life. The standard charge rate is only 0.5A and the fast/rapid charge rate is 1.25A. Never charge this cell at above 1.25A.
The cycle life rating in the datasheet is decent but I have not tested it.
The two cells I tested delivered 2689mAh and 2711mAh. This is well above their 2550mAh nominal capacity rating. Their consistency is average for cells I’ve seen from the larger China cell manufacturers.
Two cells were purchased for testing by me.

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.
