    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 cell appears to be accurately rated and is a decent performer that should be available at a lower price. It doesn’t perform quite as well as the Samsung 30Q but where cost is the priority, and as 30Q’s become harder to find, this could be a good cell to consider using.

    The two cells I tested delivered 2999mAh and 3002mAh. This is fantastic consistency for a cell from one of the large, established China factories. Both cells tested essentially at their 3000mAh capacity rating but like the cells from the bigger manufacturers I prefer to see the typical capacity delivered by a cell be decently higher than its rating. This is a true 3000mAh cell though.

    Two cells were donated for testing by 18650BatteryStore (18650 Battery Store - Lithium Ion Batteries, Chargers and Accessories). Thank you!
