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 great performer and its 15A rating seems reasonable. Its capacity rating is a bit exaggerated though. The 25A “max” rating is undefined and useless, ignore it.
It performs a little better than the Samsung 50E3 and the same or better than other 5000mAh 21700’s. Like all ultra-high capacity cells it performs best at under its rating. I recommend staying at 10A (about 30W) or lower. I do not know how this Vapcell’s cycle life compares to the long-lasting Samsung 21700’s.
The two cells I tested delivered 4990mAh and 4991mAh. This is fantastic consistency but is below this cell’s 5000mAh rating. It’s just by a little but the measured capacity should be well over the rating since there are differences in capacity between cells in a batch. Since I cannot have the lowest capacity cells in the batch I am rating these at 4900mAh.
Two cells were donated for testing by Vapcell (18650 batteries, Vapcell batteries, 18650 Chargers). Thank you!
