Three small hook - or rather tick - but there are still justified and probably also the cheaper price compared to the same product from the Apple Store:
1. The "White" the new battery is more a very light gray,
2. the plastic part (outside) of the battery is one millimeter smaller than that of the old batteries, so that a slight gap between the battery and the notebook remains,
3. one of the small green LEDs on the outside of the battery, to check the battery status, lights up darker than the other.
Because, as I said, the rest speaks for an original product, I would imagine that this is "B-Ware" is that has been sorted out by the quality management at Apple. As long as the reasons for screening limited to these three points, I can therefore absolutely live! The most important thing as a battery is finally the ability to supply the notebook with electricity, and even if the battery still should keep 3 year olds (the old I have 5 years in operation and completely over the not yet ... ) I am therefore satisfied. After no more than 8 years as a notebook must then could just be dismissed in retirement ...
If the battery capacity subside dramatically in the next few weeks, or something else worth mentioning happen, I'm wearing the genre here after. Until then, there are first 4 stars (5 had been there when the three hooks would have been).
