Trouble
Unfortunately the Blackberry did not accept this battery fully. Seemingly a voltage problem. Charging the battery fully within the phone and then briefly disconnecting it was a nice task (sometimes for hours), every time the battery had run low or the phone got switched off. Otherwise the battery got shown as defect. Once the phone booted up, it was okay until the next time the phone got switched off. Interestingly it did not last very long either and has been replaced with a different product since a while now. The new battery works perfectly fine.
