Can I use a new charger for my older Sonicare toothbrush?
Yes. The Sonicare toothbrush models listed below can be charged on any recently purchased Sonicare charger, whether that charger has a sanitiser or not.
However, prior to doing this, please check the model number listed on the bottom of the charger. The model number begins with the letters HX. If the HX number on your charger ends with /B – for example, HX6100/B – the battery indicator light on the handle may flicker or remain off entirely if the handle is left on the charger. This does not affect the function of the toothbrush, and the toothbrush handle will still fully charge:
