After a while only were able to use on the charger our baby monitor, finally the old battery has completely given up the ghost. Eternally flashing red light and receiving part often no function. After inserting the new battery (cord has 100% fit) works the receiving part 1A again. Even without charging station (longer life for the battery) the battery lasts loose 9-10 hours. A cheap alternative to an original battery or even a new baby monitor! Absolute buy recommendation!
