Anyone tried to change the NiCad in a Sonicare?

Most NiCad-powered things use standard cells you can replace for a few pounds, even if the manufacturers say you can't. Sonicare toothbrushes are sealed, and I'm wondering how best to try and open it to see if it uses standard cells. At the moment it is still working, but only holds a charge for about 3 days (used to be two weeks+). I have had it quite a few years now, so I'm not complaining, and it is a *superb* brush that has saved me from the hell of receding gums that Oral-B, WaterPik & Co. could not help with.

Anyone here tried this and succeeded (or failed)?

I have my scalpel poised for the first incision... :-)

Ta,

Sorry, cannot help with the sonicare, but the Braun toothbrushes actually tell you how to open them, and then proceed to tell you how removing the battery will destroy the unit!

They instruct you to remove the batttery, and return it to Braun for correct disposal - yeah right! (OK I know this is what you SHOULD do - but at least the latest ones have no cadmium!)

I did take one apart once, and yes, they were quite right - I did break the toothbrush.

I just wait for the half price offers to come round, and then get a new one - which seems a terrific waste.

Even cheaper to use a traditional toothbrush I know, but not so effective on plaque (IMHO).

Keep trying,

Regards,

White.

Looks like you cannot do it, The website says

"The battery inside your Sonicare cannot be replaced, but is easily removed for recycling."

It then tells you how to smash open the Sonicare to take the battery out.

Thank you! I hadn't found that page. Now I know there is a nut lurking under the rubber bit, I know where to start my attack when it finally dies. I suspect from the rest of the article that the battery is bonded in to the base of the handle with glue, but if I can prize it open enough to see what is there without damaging the clever bits beyond repair, I have a chance.

Ta!
