Why is my Oral-B 3764 handle not charging?
- RRobert WalshAug 10, 2025
Your Oral-B Electric Toothbrush handle might not be charging because the battery is at a very low level, and it may take 10-15 minutes until the display turns on. Also, the ambient temperature might be out of the valid range (less than 0°C or greater than 40°C), or the charger may not be properly connected. To resolve this, charge the handle for at least 30 minutes. It is recommended that the ambient temperature for charging is 5°C to 35°C. Also, ensure the charger is connected to the mains voltage.
