J**Z
NOT a new Battery!
EDIT: after running MSI's Battery calibration tool multiple times and doing a complete charge and discharge cycle 3 times, the battery is even worse now at 30..4 percent wear in HWiNFO as well as the powercfg tool in the command prompt. I have already requested a return...Complete waste of time. This battery, while a genuine one as far as i can tell, is even worse than the original one I took out. The battery I received already has 25.5 percent wear on it. (See pictures) I thought i was gonna get a good one as the ones on eBay were cheaper but I guess you don't always get what you pay for.Note: If you buy this battery please use HWiNFO to check the battery health before you return it. You might get lucky and get a good one, unlike me.
