After the old Battery (possibly due to an electric shock -> bad outlets abroad) was virtually destroyed, needed a new battery. Here I found the choice of> 30 or 10 degrees. Since the risk of failure is always a purchase, the choice fell on the already well-rated inexpensive battery.
This battery is (even fitted the old man, but was a little wider, also you could not specify the APN number) with the original in terms of size and marking identical.
After installation, I was initially shocked because not charging is displayed. The next day, however, were the 100% since. Now, after 4 days of occasional use (mainly WiFi) is now the level reaches 37%. All in all, an improvement over the long been disused battery replacements. Anonymous comparison values (setpoints) are not available to me in order to assess the capacity.
