Toothbrush Battery Replacement Service

At Ionic Industries we often get asked if we offer a toothbrush repair service for replacing the battery in your electric toothbrush. Although we don’t currently offer a toothbrush battery replacement service ourselves we are always interested to hear about businesses both in the UK and around the world that offer this service.

We’re keeping a list of businesses (see below) that offer a toothbrush battery replacement service and who can repair your toothbrush for you. This includes Braun Oral-B, Philips Sonicare, Colgate Omron and other toothbrush models. If you find a good repair business (or are one) then please let us know and we can add it to the list below. We’re interested in repair shops that you can visit and drop off your toothbrush for a battery replacement, as well as mail-in businesses where you can send your electric toothbrush through the post, they repair it and send it back to you.

We know that customers of ours have bought their new battery from us and then taken the toothbrush and battery to a local repair shop to have the repair carried out. Customers have used their local television repair shops as well as phone repair and domestic appliance repair shops, so let us know your tips and experiences in the comments section below. If you want to put a website link in your comment please remove the letters “http” otherwise it will be automatically deleted as spam. Alternatively, email us. We look forward to hearing from you!

Also, do see if there is a Repair Cafe local to you. These volunteer-run cafes take place all over the UK, USA and around the globe. They are a great way to access the skills, tools and knowledge to get your toothbrush repaired and running again.


The toothbrush battery replacement services listed below have not been checked or endorsed by Ionic Industries, so please contact them directly and assess their suitability for yourself before using the service. Some toothbrush repair services will require that you purchase the new battery from us first, then send or take both the battery and your toothbrush to them.

  1. Great info here. I am part way thru replacing the battery in my Oral B Triumph professional care 9000. I noticed that there are two very fine copper wires near the brush end of the unit. The “left” one is firmly soldered on, but the “right” one appears like its not soldered on. The unit still rujs when I push the button. The wire thats not soldered on probably should be? I must have broken it when I was handling it. I think I will solder it back on?? Any advice? Thank you. Roger Moyer, Ontario, Canada

    1. Best to solder it back on Roger! On the 9000 (a v1 Triumph model.) These wires are most likely to be for the brush control circuitry to detect that the motor is running by sensing the oscillation of the shaft.

  2. where can i buy the battery in canada?

    1. You can buy a battery from us. We deliver to Canada.

  3. How much does it cost to have the battery replaced through service ?

    1. You need to contact each service provider and ask them.

  4. How do i know that the battery is dead? Because when i charged the toothbrush it shows 3 bars light up. When i press on the mode button it lights up with a bleep but when i press the on button nothing happens!
    Any advise given would be gratefully received.
    Thanks in advance

    1. What is the type number marked on your toothbrush Narinder?

  5. Hi
    My Oliver James brush has failed. I assume it is identical to some other main name brand, so does anyone know what that might be? Or does anyone know which battery might fit it? It’s a sonicare brush, only about a year old.

    1. Hi Sally, I haven’t seen one in the flesh, but the Oliver James Sonic toothbrushes look very similar to the Philips Sonicare DiamondClean toothbrushes. So you might be able to open it up in the same way. Do send us an email with some digital photos attached once you get it open, then we can advise on the battery.

  6. My oral b triumph v1 stopped on its own and then started up. I finally got it to stop when I placed it back in the charger. It now doesn’t work. My charge indicator on my oral b triumph v1 shows fully charged. When I take it out of the charger for awhile and then put it back it indicates that it is charging.
    I have taken my oral b triumph v1 apart to replace the battery. My battery has a voltage of 1.3 or close to that number.
    Do you think it is the battery or is it time for a new tooth brush?
    Thanks in advance……..Paul

    1. It sounds like there could be moisture inside the handle causing it to turn itself off and on. Open up the handle and let the internals dry out for 24 hours. Reassemble it then follow our toothbrush care tips here to minimise the chance of moisture re-entering the handle.
      Separate to that, if the battery only lasts a few days after a full charge it could also be time to replace that.

  7. Are there any Repair Cafe’s or the like in Argentina? I have an Oral B Sonic Deluxe that needs to have the battery replace and I have 12 thumbs on each hand. Are there any places that sell reconditioned heads for my product?

    Thank you.

  8. My Oral B Professional no longer charges (the green light does not come on). Everything still worked until I ran the battery down. Any ideas please?

  9. I charged my Oral-B Pro 2 2500N, took it off (it worked) and it left it overnight. By morning it was completely dead. Did this again and the same happened.
    I know the charger is working, because we use it for another toothbrush.
    As it seems to be charging, but not holding it’s charge, is it likely to be a battery fault rather than a bad joint?
    I will check it for water ingress, as I remember that I had given it a light rub with a nail scrubber this week, but wondered whether it sounds like a battery fault. (It’s just over 2 years old.)

    Many thanks

    1. Hi Tina, if there is no water ingress then it sounds like a battery fault.

  10. I have fitted many replacement batteries in many devices including toothbrushes. You will need to have some expertise in changing soldered on batteries as on toothbrush internals there is a strip down procedure that you follow which includes many de-solder points of fine wires before getting to the battery solder points. I would not reccomend stripping your equipment if you have never carried out this type of work before as it takes some patience and experience as well as soldering tools and fine picks to assist you in your process.

    1. Thanks Mike, the older the toothbrush is the easier it is to replace the battery. Don’t be afraid to have a go because if the toothbrush is already failing you have nothing to lose! Repair guides for lots of different toothbrush models are available on our guides page here. You can also use a repair service as mentioned above.

  11. Hi, I wonder if I fried my toothbrush when I tried to charge it in Australia when I;m from Canada.
    Is there any solution to this, as my toothbrush is not accepting a charge from either of my chargers from home. 1 house plug, and 2 USB.
    Thanks, Lorraine

  12. I live in Warren, Michigan, USA and need to find a place that can replace my battery in my oral b toothbrush. It’s the kind that needs soldering.

  13. Hi, thanks for the useful information! I have a Oral B Triumph Professional Care v2 that behaves like the battery is low, but I have discovered that gently pressing down the head, vibration is much stronger. Do you think is a problem of battery or of the pressure sensor? Thank you

    1. This sounds like a fault with the toothbrush. If you open it up and inspect for water damage, then let the internals dry out for 24 hours this might solve the problem for you.

      1. Thank you I will try!

  14. Hi, I have some problems with a Braun 3766, which had stopped working – initially the motor would run for just a second or two and stop. If pressed again, the same would happen. I tried to charge it but no lights (Green or red) came on. After a while the motor ceased to start at all.
    I purchased a new Li-ion battery from Ionic which I have just fitted but, although I can measure 3.75V across the terminal tabs and I get a continuity reading across the charging coil, the motor does not run at all and no lights appear even when on the charger.
    I have concluded that there was nothing wrong with the original battery, which measures 4V dc (I should have tested it before ordering the new one 🤦🏼‍♂️).
    If the battery +ve terminal is briefly shorted to the motor +ve terminal the motor rotates (but accompanied by an acrid smell).
    Incidentally, I have disconnected all solder points and started again but with the same result.
    I replaced the Ni Mh battery in my model 3756 using your excellent guide and it continues to run and charge satisfactorily over a year later, so I’m disappointed I couldn’t achieve a similar result with this one ☹️.
    Are you able to offer any advice please?
    Kind Regards,

    1. Hi John, this sounds like a fault on the PCB. Either water damage (staining, corrosion to tracks or components, crystal formation) or a damaged or moved component. The battery voltages look good and normally you should get a charging light after the brush is on charge for an hour. You could try cleaning the PCB with isopropyl alcohol and a brush. However, the smell when you directly connected the battery and motor could be from a damaged component.
