I’m disputing the capacity of rechargeable batteries, they should have 1200mAh but I measure less than half of that.
Aliexpress stepped in and rejected the evidence: “Please show us your test process of the capacity in a clear video（please do not use the IMAX B6 to test the capacity of batteries since it was not professional testing tool”. Does anyone have any experience with proving battery quality to Aliexpress? What ‘professional testing tool’ does Aliexpress actually accept? (I guess none of the cheap constant current loads on Aliexpress qualify as ‘professional’ – although I actually only need a resistor, a multimeter, and a clock to prove that the capacity is below a certain threshold, but I have the feeling that’s not ‘professional’ either, although it’s very solid electrical engineering.
