Yes I did so. And I added a picture of the capacity test of the LiitoKaala to proof it for other customers.
Additionally I got the money back for all of the batteries. Most of the sellers even didn't disagree that the capacity is wrong.
But the seller of the "Dolidada" 15.000mAh argued, that I did the test wrong and his batteries do have the specified capacity.
I told him to show me a proof of any testing method he prefers and without photoshopping.
No answer - money back :sleepy:
Then I though about what todo with these cells now.
Recycling? Somehow a little too bad.
Selling again? But they are scam.
So I decided to sell them on eBay with detailled results from my test just to warn people.
I bought the batteries about a month ago, along with other models, and tested them.
Since I no longer need them, I sell them again.
Manufacturer / type: Ultrafire SJ 18650
Capacity according to the manufacturer: 6,000mAh
Working voltage: 3.70V nominal
Charging voltage: 4.20V maximum
Discharge current: 3.3A
Dimensions: 18.2x65.1 mm
Weight: approx. 35 g
Protection circuits / protected: no
the printed manufacturer information is greatly exaggerated and does not correspond to the values that I have determined.
A LiitoKala Lii500 Engineer was used for the capacity test with the standard settings of the "normal test" of 1.0A charge current / 0.5A discharge current.
You can find information on the measured capacity in the pictures.
On request, I can also send you the link to the detailed test including evaluation and videos.
Make an offer only if you are in agreement with it.
I set the price very high so no one would buy them and the auction will last very long and many people can read this.
example on eBay: 8x 6000mAh Ultrafire SJ 18650
