Batteries Available for Philips Sonicare AirFloss Flossers

Philips have been producing their Sonicare AirFloss range of water flossers for a number of years, and the internal rechargeable batteries start to lose capacity after a few years of use.

  1. ebay link does not show any US sellers of replacement battery for Airfloss Ultra. Please let me know of any such suppliers. thanks

    1. Follow the eBay link and search for ‘airfloss akku’ or the item number 113813490786 for one that sends to the USA.

  2. What is the code number for the battery for a HX8222/02 thanks

    1. You can use the links above to find a suitable rectangular battery. Your HX8222 is in the HX8200 series of Sonicare Airfloss flossers so a battery for an HX8210, HX8230, HX8240 etc. will fit.

  3. I could not get the Sonicare Airfloss opened. Is any manual available for the replacement, including opening the airfloss (HX8140)?

  4. thanks for the battery info. airfloss up and running.

  5. Many thanks for this!

  6. welke accu zit er in een hx8340, heb je hier het typenummer van?
    op de accu staat 362543c 290 mAh 3.7 volt.
    Kan alleen de 500 mAh versie vinden, past deze ook?

    1. The original battery in your Airfloss is 3.6mm thick by 25mm wide by 43mm long. It looks like the 500mAh battery is 6mm thick but the same width and length. Is there room inside your flosser for a thicker battery? You could tape some card to your original battery to see if it fits.
