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 looks the same as the Molicel P42A but performs just a little bit worse than the 2021-dated P42A’s I have tested. I don’t think you will notice the difference in actual use though.
In my opinion this cell’s 20A rating is conservative. That will help to reduce risk, increase performance, and extend overall cell life. It is nice to see a cell wrapping company do this as so many of them exaggerate the current ratings.
Unfortunately the 4200mAh capacity rating of these cells is slightly exaggerated. The two cells I tested delivered 4077mAh and 4098mAh. Since I cannot have the lowest capacity cells in the batch I am rating them at 4000mAh. This is the same as the P42A’s minimum rating.
These cells should be available in Europe so if you are unable to find Molicel P42A’s there you could try these.
Two cells were donated for testing. Thank you!
