This is a retest of this iJoy cell and they are still overrated to the point of absurdity. While they performed better than the last time I tested them the iJoy\u2019s perform no better than the Keeppower\/Vapcell\/YDL 18350\u2019s I recently tested (9A-10A, 1000mAh-1100mAh rated).<\/p>\n

To extend cell life, minimize voltage sag, and increase your safety margin, I recommend staying at 7A-9A or under for these iJoy\u2019s. That\u2019s about 20W-27W per cell.<\/p>\n

These cells have a VERY thin paper top insulating ring. While paper will not melt if the cell overheats, which is good, I strongly recommend not allowing any eliquid to get on the top of these cells. It could possibly soften the ring and allow it to become damaged easier.<\/p>\n

The two cells I tested delivered 1415mAh and 1443mAh. This is decent consistency for a China-manufactured cell. I am rating this cell at 1400mAh. Its very high internal resistance means that it has a huge amount of voltage sag though and it will not run for any longer than the better performing 18350\u2019s.<\/p>\n

Like all the small cells I\u2019ve tested the cell-to-cell performance consistency for these iJoys is not good. There\u2019s not a huge difference between cells but you might notice it if you have one of the better ones and one of the worst ones.<\/p>\n

Two cells were were purchased by me for the purposes of testing.<\/p>\n

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: https:\/\/www.patreon.com\/batterymooch<\/a>.<\/p>\n

These tests 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 \u201crewrapped\u201d batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.<\/p>\n

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 protected battery pack. Never exceed the battery\u2019s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.<\/p>\n

Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.<\/p>\n
