I just replaced my laptop's battery with a genuine replacement off ebay. While the actual battery is from HP itself, it appears to not be new (it was listed as new). According to powercfg's battery report and HWinfo, the battery has 17.2% wear on it with only 2 cycles. It's a 50wh battery (HWinfo reports it as 48wh), but the available capacity is 40wh. How can this battery have such high wear with only 2 cycles?
