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 cell is a pretty good performer but its low capacity means a very short run time compared to the Molicel P42A or Samsung 30T if you go under 3.2V or so. It equals the Samsung 40T down to about 3.3V but below that the 40T’s higher capacity holds its voltage up better.
This cell gets as warm as the P42A, 30T, and 40T but its low capacity (shorter run time) means it doesn’t have a chance to heat up as much so it could possibly have a 40A rating. The 60A “max” rating is undefined and useless, ignore it. Cycle life matters when setting the current rating but I have not tested its cycle life and I do not know how its overall life span compares to other cells.
The two cells I tested delivered 2062mAh and 2101mAh. This is not great consistency but it is typical of cells from some China manufacturers and exceeds this cell’s 2000mAh rating.
Two cells were donated for testing by Vapcell (18650 batteries, Vapcell batteries, 18650 Chargers). Thank you!
