Externally, the battery pack is identical to the built-in iPhone 4S battery. The part numbers and DataMatrix codes fit extent - it seems an original iPhone 4S to its battery.
The iPhone displays the Ladeicon, then boots repeatedly (20-30 times) and turns on after some time and work.
It seems then to load, pulling the plug on the iPhone is it off immediately - even after two hours on stream the same result.
The resultant of battery seems to me to be absolutely at the end of its life and is not usable.

Update 3:
The new battery (exchange) makes a very good impression, he kept quite well, an accurate assessment followed by a few days. Then I can make a statement to capacity. Installation is relatively straightforward and simple, it is important to pay attention to the connection part to the back, otherwise you have almost no reception.

Last update:
After some use, I can say now is that the same as the battery is related to my original battery.
The Running / standby times are better than with 1.5 year old original battery, the differences are smaller than expected, but I am very satisfied.
Probably my original battery is still in much better condition than I originally suspected. Since I telephone much advantage is after about 5h usage time of battery at the end.
Original battery closer to 4.5 hours and the topsy here closer to 5.5 hours.
