! Warning! When I put this in my battery as Siemens device, this one began to make "beep" ..... "beep" when charging. I wondered if you had not ... unplug everything apart. But after a while (20 minutes maybe) more noise and battery began to charge normally (for about a few hours) Since, it is perfection! I found my such as new with its battery which takes super long. For a price more ... really decent! Thank you!
