  If your Oral-B Electric Toothbrush handle isn't charging, it could be due to a few reasons: 1. The battery may be at a very low charge level (0%). In this case, charge it for at least 30 minutes; it may take 10-15 minutes until the display turns on. 2. The ambient temperature for charging might be out of the valid range (less than 0 °C or greater than 40 °C). The recommended ambient temperature for charging is 5 °C to 35 °C. 3. The charger may not be properly connected. Ensure the charger is connected to the mains voltage.
