x220 Hackintosh Battery Monitoring

Hi, I've got a x220 hackintosh up and running. I recently got a new battery for it. (Lenoge) The battery should be 5200mAh according to battery and box it came it. Using both battery health 2 and the system information it reads as max 4400mAh. I booted to linux on a USB stick and in that the power manager said the battery was Fully Charged(design) 47.Wh,Fully charged 53.8wh(113%), voltage 11.3V. An online calculator says 47Wh at 11.3V is 4203mAh, 53.8Wh is 4761mAh. Before I contact the battery seller to report a problem, is there any reason that a hackintosh should report wrong figures ? Or is this just the result of using a cheaper replacement ? The original Lenovo battery is reported in battery health 2 app as original max of 5600mAh.(though is current max is 2800mAh). Thanks.
