Is the battery of your Philips Avent digital thermometer low or empty? Easily replace the battery yourself. Follow these simple steps.


The dot on the right side of the display of your Philips Avent thermometer will indicate when your battery is low. Steps on how to replace the battery:

  2. Carefully remove the battery from the tray. Note: do not pull out the battery tray (A) more than 1 cm, or the sensor might break off. You have to pull out the battery tray a little to access the battery.
