Approximately 3 weeks after the purchase of the battery made limp. And I had an important Meeting. Had then a second battery installed, this was empty for 2 days. I must say that this clock is beside the window. So he enough brightness. Shortly thereafter, the clock face lights no longer shone. Wanted to send him back, but was no longer the bill. He is now, with the original battery as a clock in the next room and running. But will no longer use it as an alarm clock, because I trust in this have lost.
