I bought 4 pcs of Bestfire 18350 1500mAh, I charge with a quality charger for about 100 dollars, the capacity of the batteries is in the range of 877mAh to 975mAh (tested for a week). Previous batteries with a capacity of 1200mAh had about 950mAh to 1100mAh which was acceptable, 1500mAh is in my opinion a scam.
thanks
