works schonmal

My old battery approached the 1,000 charge cycle and held barely 2 hours.
So a new was needed, of course, there should be an original.
Original seems this battery, it is the same as the replaced (with the exception of two stickers with warning signs) and after uncomplicated installation (please note: Triwing screwdriver needed) will my MacBook 5856 mAh capacity at.
The battery was charged to about 40%, the state is, according to system information, as expected, good.
But: The battery seems to be B-stock (hence the price) because the protective film left behind sticky residue that are first removed with difficulty had to (1 star deduction) and he has 2 charging cycles under his belt. Also can be seen at very close look that the battery has been installed once (very slight scratch marks, where the screws to hold battery).
For the price I can, however, ignore the fact.
The long-term test is still pending ...

UPDATE:
Now, after 4 charging cycles in my laptop shows me my system information a load capacity of 5659 mAh at, is therefore already fallen by almost 200 mAh, which corresponds to a reduction in the loading capacity of about 50 mAh per charge.
Should the battery during the coming loads behave further, he will survive not even 120 charge cycles.
I am very curious how the battery is still beating ...

UPDATE:
After about 50 charge cycles the battery has good "leveled" and has made even higher full charge than with the last measurement:
Number of cycles: 54
Full Charge Capacity: 5777mAh

Overall I am very happy with the battery now and can recommend the purchase, because the installation is straightforward, the battery the original closely matches and is significantly saves money!
