Here https://www.ebay.com/urw/write-review/912268341?_itm=351846592589 I made the following comment with the title "Batteries of very poor quality" and the content "These batteries, after 3 charging / discharging cycles, have only 400mAh. They only have a weight of 14g. Other 2200mAh batteries have 28-29g but they really have 2200mAh. I broke a battery and found only 1/3 full. These batteries are very weak. I do not recommend buying them. Money thrown."
Ebay only publishes positive ratings?
