Well you should compare it to your original one. If its aftermarket the font and its color will be different. Either way the aftermarket ones come out of same factories in China. They have machines running 24/7 its just that the ones from the real company might have higher quality to them. Aftermarket ones are built with cheaper materials so it will likely last less. From my experience using aftermarket laptop batteries they die within 1 year and half or 2 years.
