These tests below only note my personal opinion for the 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 can be 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. Never use them outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous discharge rating (CDR), never let it get colder than 0°C or hotter than 60°C, and keep the plastic wrap and top insulating ring in perfect condition. Never use a battery that is physically damaged in any way.
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
It’s been a year since I tested this cell so it’s time for a retest. It’s a good performer, doing slightly better at 5A than all 21700’s except the Samsung 50S. At 10A it equals the Molicel P42A and is beaten (by a bit) by the Samsung 50S, Molicel P45B, LG M50LT, LG H50, and BAK N21700CG-50.
The datasheet gives this cell a 9.8A continuous current rating and that seems reasonable. Samsung also gives it a 14.7A non-continuous rating but you must keep the cell temperature below 70°C.
The two cells I tested delivered 4979mAh and 5042mAh which isn’t very good consistency for Samsung cells but it exceeds their 4900mAh rating.
