Oral hygiene plays a vital role in maintaining a healthy smile, and your toothbrush is an essential tool in this process. If you own an Oral B electric toothbrush, you may wonder how to change its battery when it runs out. In this article, we will provide you with a step-by-step guide on how to replace the battery in your Oral B toothbrush.

Step 1: Gather the Necessary Tools

Before you begin, ensure that you have the required tools handy. You will need a small Phillips head screwdriver, a new battery (compatible with your Oral B toothbrush model), and a clean, well-lit workspace.

Step 2: Remove the Brush Head

Start by removing the brush head from your Oral B toothbrush. Hold the brush head firmly and twist it counterclockwise until it detaches from the main body of the toothbrush. Set the brush head aside in a safe place.

Step 3: Open the Battery Compartment

Locate the battery compartment on the bottom of your Oral B toothbrush. It is usually covered by a panel secured with a screw. Use the small Phillips head screwdriver to carefully unscrew the panel and set it aside.

Step 4: Replace the Old Battery

Once the battery compartment is open, you will see the old battery. Gently remove it from its position, taking care not to damage any surrounding components. Dispose of the old battery responsibly.

Step 5: Insert the New Battery

Take the new battery and insert it into the battery compartment, ensuring that the positive (+) and negative (-) terminals align correctly. Check your Oral B toothbrush’s user manual to verify the battery’s correct orientation.

Step 6: Close the Battery Compartment

After inserting the new battery, carefully place the battery compartment panel back into position. Use the screwdriver to tighten the screw, securing the panel in place. Make sure it is firmly closed to prevent any water or moisture from entering the toothbrush.

Step 7: Reattach the Brush Head

Now that the battery is replaced, it’s time to reattach the brush head. Align the brush head with the main body of the toothbrush and twist it clockwise until it is securely in place.

Step 8: Test the Toothbrush

Before putting your toothbrush away, press the power button to ensure that the new battery is functioning correctly. If the toothbrush powers on, you have successfully replaced the battery.

Step 9: Clean and Store

Lastly, clean your Oral B toothbrush under running water to remove any toothpaste or debris. Dry it thoroughly with a clean towel and store it in a hygienic and dry location until your next use.


Changing the battery in your Oral B toothbrush is a simple process that can extend the lifespan of your toothbrush and help you maintain optimal oral health. By following these steps, you can easily replace the battery yourself and keep your smile shining bright!
