Battery conforms to the original. Remember not to over tighten the two screws that hold the battery if it goes too press the trackpad and the game will be too small to click thereafter. Remember to make a pram loaded at startup and then discharge the battery 3 cycles. Original battery at 5800 mAh autonomy it has 5900 mAh 0 load cycles so confrome to original battery. For now I'm happy I managed to hold 6h with but for people who complain of chrome look coterie for those who sail with this browser because for my part 4h of autonomy with chrome. C is an energy killing software.
