When the battery is discharged to 2.5V, the discharge capacity of large current may exceed that of small current. But there won’t be much difference. 
Nice test， :+1:
sincerely apologize for the delay in shipment.
Hope to be in your hands as soon as possible.
Thanks you very much 
Why is that?
energy is More important。 AH*V=WH
Because of temperature induced chemistry reactions inside the cell. As a general rule heat improves the performance to some extent, chemistry dependent of course. While lots of modern cells do not show increased capacity at larger discharge ratios, increased heat reduction in internal resistance is common.
:-)
That was my thought as well. I have seen li-ions that were cold and run under a 3 amp discharge actual slightly increase in voltage as they were being discharged because the internal heat from being discharged warmed the cell which gives it the ability to provide more current. Since the discharge current is constant the cell doesn’t have to work as hard warm so the voltage goes up slightly. A warm cell will give more capacity in a discharge test than a cold one in my experience.
So do I.
Ordered 2 pieces of 10440 batteries from the aliexpress store. Will check them out
Thanks again for getting us a new type nice battery Dennis.
Got my 16340 cells from Illumn.
Capacity test using 500 mA discharge current on Lii-500:
. 
IR, measured using a DMM and resistors:
Cell 1: 0.21 Ohm
Cell 2: 0.20 Ohm
10440 shouldn’t have a button top option? I will see if it will reach the positive contact in my DQG Tiny.
we have button top , we will add it in web,sorry
Thanks for the test, a bit low cap
we test it more than 750mah
Is it possible to add this button top to my current order? It is awaiting shipment at this moment.
yeah， contact Ali Customer service staff to change it
No problem. It may just be the nature of this charger/analyzer (Lii-500). It consistently indicates lower capacity figures on all cells I test with it by about 5-6%.
If I am correct, Vapcell measures capacity with 0.2C, which gives 150mA instead of 500. Maybe, this is the reason of the difference?
The chart they posted (see below) shows them measuring capacity using various current levels, starting with as low as 0.5A and going up to 8A. At 0.5A, their tested capacity is 812mAh. The main difference is their cutoff voltage is 2.5V. Mine is 2.8V, but there can’t be much capacity left there at that point.
I have kept 3V in my charger (default value), but according to the graph that also wouldn’t make much difference.
BTW, I just repeated what they wrote on the Ali site:
Typical Capacity 800mAh (0.2C discharge)
