Funny thing, thanks to this charge_counter I’ve discovered that I most probably have some Chinese battery inside my XA2 Ultra, probably one of those “5600 mAh” one can find on Aliexpress, be it a true capacity or the battery electronics just reporting it so. I bought the XA2U second hand and the seller was mentioning that battery was replaced by the service but I had no idea that he meant a third party battery and a “service” that uses such strange batteries… The funniest part is that it works OK, gives me very good working time, and the charge_counter decreases in a correct pace as the battery discharges, so it might mean that this 5600 mAh capacity is actually (close to?) real…
