After installing the batteries, I noticed first that the touchpad of MacBooks suddenly clatters somewhat. The reason is that this battery is minimal thinner than the original battery. Unfortunately I had then but also notice that after Anlehrnen the battery (at least three times fully charge and discharge), which is Health of this battery in only 80%. (Measured with iStat Pro and coconutBattery). That's worse than the old Origianlakku. For this reason, the battery went back. The settlement took place smoothly. The service of the supplier is thus properly.
