In June of 2017 I got 6 X Aspire 18350 1300mAh 15A cells.Today after 280 plus cycles their capacity is almost equal to the brand New Vapcell M11 18350 1100mAh 9A cells I got today!
I know it was used other cells. I think KPower was one and 3 years ago Vapcell had a 18350 1100mAh cell that HKJ tested.It was labeled 10A.It had 1100 Plus mAh.
I had a couple of those Vapecell 18350 just self discharge to below 1v — they’re only a couple years old — the other 6 are just fine
Some of my original VTC5 and Panasonic bs that are at least 6 yrs old still test as new
