Yes, the original battery in the Braun Oral-B model 3756 may be weak and not holding a charge. One user reported that it only lasted 4 days between charges and had a capacity of just 1100mAh, even though it was the longer 49mm type. Replacing it with a higher capacity 2200mAh battery is suggested to improve performance.
