While both of the cells I tested delivered a bit over their rated 700mAh of capacity they were poor performers with an exaggerated current rating. Their large voltage sag made them essentially unusable at 10A, as displayed by the huge drop in the Wh delivered between 5A and 10A.
I am estimating this cell’s ratings at 5A and 700mAh. Current ratings for high internal resistance batteries like these are a combination of the temperature the battery runs at and how badly the voltage sags, i.e., its Wh specs.
This is the first 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 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.
