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 lower capacity 18650 that is not a great performer but it should be available at a lower cost. This can make it a cell to consider for cost-sensitive applications where a high datasheet current rating is needed.
While the datasheet gives it a 30A “max. continuous discharge” rating this is a “temperature-limited” rating. It says you can use this cell at 30A but you must never let it get over 80°C, which is actually quite hot. However, I recommend staying under 20A to reduce the amount of voltage sag and to increase cell life.
The two cells I tested delivered 2107mAh and 2125mAh. This is good consistency for a China-manufactured cell.
Two cells were purchased for testing by me from 18650BatteryStore (18650 Battery Store - Lithium Ion Batteries, Chargers and Accessories).

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.
