This cell has an accurate capacity rating but is a poor performer. Even at just 5A it delivered less than 1/2 the energy of the other 18350 cells I tested due to its incredibly high internal resistance. This means very short run times at anything above a couple of amps.
The two cells I tested delivered 874mAh and 887mAh at 0.2A down to 2.5V.
I am estimating this Imren’s ratings at 3A and 800mAh. Current ratings for high internal resistance cells like these are a combination of the temperature the cell runs at and how badly the voltage sags, i.e., its Wh specs.
The performance of any 18350 really suffers at higher current levels due to their very high internal resistance, leading to huge voltage sag. I recommend staying under their continuous current rating. This results in much more efficient operation and much longer vaping time.
This is the fifth in a group of seven 18350’s I am testing and I will be posting a shootout between all of them after the individual test reports are posted. The top three performers will then be identified.
Two cells were purchased for the purposes of testing by me.

I want to work for the vaping community full time!

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 “rewrapped” batteries 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 protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
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.
