    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.

    This is a great performing ultra-high capacity cell that performs essentially identically to the red Sanyo NCR18650GA that I tested years ago. It’s one of the best 18650’s we have above 3000mAh but should be used at 5A-7A (15W-20W) or lower due to voltage sag.

    The two cells I tested delivered 3461mAh and 3468mAh. This is fantastic consistency, typical for cells from the big manufacturers. Both cells significantly exceeded their 3300mAh rated capacity.

    Two cells were donated for testing by Vapcell (18650 batteries, Vapcell batteries, 18650 Chargers). Thank you!
