While this cell has a useless large 40A \u201cmax\u201d current rating on the wrap it has accurate continuous current and capacity ratings. In fact, the current rating is conservative compared to other wrappers of similar China-manufactured cells. This is great to see! It helps to improve safety, performance, and cell life.<\/p>\n

I am thrilled that the continuous discharge rating (CDR) is mentioned on the wrap but I hate seeing the use of a \u201cmax\u201d current rating, particularly when it\u2019s printed a lot larger than the CDR. I hope Imren removes the max rating soon.<\/p>\n

The two cells I tested delivered 3785mAh and 3919mAh at 0.5A down to 2.5V.<\/p>\n

These cells performed well, essentially equal to the Golisi S35 and Efest purple 35A 3700mAh 21700\u2019s.<\/p>\n

I am estimating this Imren\u2019s ratings at 25A and 3750mAh.<\/p>\n

Two cells were donated for the purposes of testing by Liion Wholesale (http:\/\/www.liionwholesale.com<\/a>). Thank you!<\/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 and testing 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, LG, Panasonic, 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
