    Philips ONE battery replacement instructions

    Published on 01 July 2024
    Battery replacement: 
    Your power toothbrush is powered by a replaceable AAA-battery*. A single AAA battery should provide enough power for 3 months (180-2 minute brushings).
    * Only replace with a 1.5V Alkaline AAA battery with this toothbrush.

    Before proceeding, make sure your hands and product are dry when you insert the battery.

    1) Insert a coin into the coin slot at the bottom of the handle and turn counterclockwise. Gently shake the battery out of the handle. 

    2) Insert a fresh AAA battery into the battery compartment. Make sure the + and - poles of the battery point in the right direction. 

    3) Place the removable end cap back on the handle and use a coin to turn clockwise until it is secure and the lock indicator markings on the handle and end cap line up.

    Note: If the indication on the handle and end cap do not line up, it may result in your toothbrush not working.
