These tests below only note the ESTIMATED ratings for these batteries 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 personal injury or property damage. They are not meant to be used outside of a physically and electrically protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition. Use of any of these batteries is AT YOUR OWN RISK. Testing batteries at their limits is dangerous and should never, ever, 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 appears to be a rewrap of the great performing YDL 18350D cell used by other companies, probably the best 18350 available now. The 9A rating seems to be accurate but, like the other cells using the YDL 18350D, this cell has a slightly exaggerated capacity rating. The Yong De Li New Energy Company (YDL) gives their 18350D a 15A “max discharge current” rating. Notice that this is not a continuous current rating. It seems to be for non-continuous use as the 18350D gets much too hot at 15A for that to be a continuous rating. The capacity of the four cells I tested was 1073mAh, 1091mAh, 1118mAh, and 1131mAh. While this is decent consistency for cells from the smaller manufacturers like YDL, two of cells failed to meet their 1100mAh rating. The cells I have cannot be the lowest capacity cells in the batch either. I am rating the Epoch at 1000mAh and this is typical for the YDL 18350D cell. Four cells were donated for the purposes of testing by 18650BatteryStore (www.18650batterystore.com). Thank you! Continuous Current Discharge Graphs Ratings Graphic Performance Specs DC Internal Resistance = 33.7mOhms*** (milliohms) average for the four cells. Watt-hours (energy) delivered at 15W (5A) down to 3.2V = 2.3Wh Watt-hours (energy) delivered at 30W (10A) down to 3.2V = 1.4Wh 2-sec puff count at 15W (5A) = 276 2-sec puff count at 30W (10A) = 84 I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: Battery Mooch is creating battery tests and educating vapers | Patreon. To see how other cells have tested check out this link: List of Battery Tests | E-Cigarette Forum ***I have switched test jigs, resulting in slightly lower IR readings versus my previous setup. Add 1.6mOhms to this IR value in order to compare these cells to others tested previously.
