I have all of them. The KeepPower UH1835P that i received recently from nkon, I’m not sure is the same cell (optical and performance), the negative pole is different as you can see. Capacity is around 1000mAh. The capacity of the Vapcell and Aspire is around 1100-1150mAh. All tested with zanflare C4 NOR 0.5A.
Because of the positive pole that looks the same, i think maybe same factory (Yongdeli) but newer version? Other revision? Who knows with rewrappers.
