  1. Hello, I just used your guide to help replace my Oral-B Triumph v2 3762 battery which would only last about three days before needing charging again, well it was almost three years old!
    Had a problem with the induction charging wires, as both promptly snapped upon disassembly, but a bit of resoldering and a dab or two of hot glue and it’s working fine.
    Thanks!

    1. Great to hear your success story Tom – glad to hear the guide was useful. Happy brushing!

  2. Help!!

    I was replacing my battery and had also these copper wires snap.

    I’ve done my best to unwind a small amount from the coil in order for me to have enough wire to solder back to the PCB.

    I’m not confident that I’ve done a good job…

    …case in point, I’ve put the toothbrush back together and get a red light indicating that there’s no power…

    ..I’ve put the toothbrush onto charge and can not see any sign of green charging lights at this stage.

    I’m going to try leaving this on to charge and see if there’s any life in an hour’s time.

    Please help, suggest anything, advise me as to the way forwards.

    Best regards,
    Louis

    1. The snapped wires can usually be joined back together with just a blob of solder but if you’ve unwound some extra wire off the coil that should work fine. Check the solder connections and that you got the wire hot enough to burn off the clear insulation.

  3. Excellent step by step guide. It took two hours, including a trip to get desoldering braid and a cup of tea. It would be very difficult to do without using the braid. Total cost about £12.00 and I enjoyed doing it. Thank you

  4. Hello! Thank you for your excellent instructions!
    Tell me please, can I replace the battery for a full-size battery in this model?
    I think this can be done by removing the plastic parts on the motor side.
    But it is not clear just what to do with the spring … She will have to do less or do not need?

    1. Hi Serj, yes you can fit a full-length 49mm battery in this model if you cut away some of the plastic housing around the existing battery at the positive end. You probably won’t need to do any adjustments to the spring – possibly cut it down by 2mm but first try without cutting it. Make sure you keep the plastic insulating spacer that isolates the spring from the motor casing. The full-size battery will be 49mm long, 17mm diameter with centred tags.

  5. I know I need a kit for soldering, does any one know where to buy one?

    1. You can get a soldering kit suitable for micro electronics in your local hobby shop or electronics shop. Depending on your country, somewhere like Maplin or Radio Shack.

  6. Easy peasy with the excellent guide!

    Even with modification for a 49mm long battery. A tip here could be to use a old/broken soldering tip to melt away the plastic – but do this in a well ventilated area!
    The biggest “problem” was to trim down the width of the battery terminal(s), no need to do this on the negative side on my 3762 version.

    Another thing to mention is that the motor will not run/switch on if the battery is too low. I was for a moment afraid I had broken something :O

    First full charge and first brushing done, and everything seems just fine 🙂

    1. Thanks for the feedback and the tips Tommy! When the battery is first installed, sometimes it just needs 10 seconds on charge to ‘reactivate’ the brush and it can then be tested to check that it runs/switches on.

  7. It actually took more like a few minutes on charge before I was able to test the motor. Charging started within 10sec (even if it felt like forever 😛 ), so no problem there.

    Maybe you could start selling batteries with the terminal width trimmed down? Or a small and sharp par of scissors? My regular scissors was to big and/or to unprecise for this kind of use 😛

    1. For me, too, it took a few minutes of charging before the motor actually worked even though the battery was delivered at 1.26 or so volts. I would guess that the microcontroller prefers to measure the increase of voltage before actually enabling the motor.

  8. Just followed the excellent and clear instructions, and now have a brand new battery charging in my Triumph v2. Like other posters, the induction wires snapped due to the manhandling, and one of the plastic legs on the induction ring had cracked (over time). Some soldering and Araldite have sorted those issues, so hopefully the toothbrush will be like new! Many thanks for such a good guide.

  9. Both (are there two or three?)wires broken on my Braun 3762 toothbrush charging coil.
    I’m confused, are there two or three coil wires running to the circuit Board? I’ve seen a drawing on the Internet that indicates 3 wires but I think that is a different model.
    So, my question is, are there only two Wires? I solder tomorrow….

    1. Hi John, there are only 2 wires on the charging coil of your type 3762 (and other v2 Triumph models.) It doesn’t matter which way round they’re connected.

  10. Received my replacement battery within a couple of days of ordering – thanks for the prompt service 🙂

    Spent about 10 minutes re-assembling my V2 Triumph following your very detailed and idiot-proof instructions. Brush now charging and seems to be working fine – far more satisfying to have repaired this item rather than have to throw it away. Thanks.

  11. Great guide. Many thanks for this. Much cheaper to spend £10 on a battery than heaven knows what on a new brush. And more environmentally friendly too. The design of my v2 brush differs slightly from what you show – older or newer I guess but I don’t know which. There’s just a retaining ring to be removed at the shaft end; I didn’t have to pull out what looks in your photo like a fairly long plug. At first I thorough I’d broken it, but all was well.

    Thanks again
    Chris

  12. Great guide. Without it I couldn’t have replaced the battery in my Oral B toothbrush. Very helpful indications for removing and replacing the ring on top.
    Instead of using and clipping the strips on the new battery I made them shorter and soldered 2 solid wires upon the clips. This made it easier to get trough the holes on the PCB.
    Thanks.

  13. Thank you for this great guide! I’ve just installation of the Varta battery into my aged Braun 3762, and it’s a success! Had similar mishap as other posters re. the fine copper wire terminals of the induction loop but got it working eventually. Also the plastic collar was a swine to get on! Thanks again!

  14. Hi,

    Thanks for the great guide – always good to have a go 🙂

    On my V2 brush I’ve changed the battery and when trying to turn on it flashes orange which proves the battery is installed and working, however it wont charge.

    I’ve stripped it again and noticed the coil wires were both broken so one side can be easily redone but not the other side as this appears to be sat underneath all the other copper wire.

    So will this tolerate me undoing all the wire, getting the right side back on again and re-spinning back around and connecting the left side? this is what I’ve done and still no charging lights.

    Can the copper wire be soldered or glued to the contacts to ensure connectivity?

    Am I missing something here?

    So I’ve got no charge but battery is saying flat.

    Do I need to spin the copper wire back around differently? or is it a contact issue?

    Was working before but how can I test the charging base?

    1. Hi Jamie, when a coil wire is broken you can unwind a turn of it from the coil and re-solder it to the PCB. If you have rewound the entire coil it shouldn’t make any difference. The main thing is the re-soldering. The wire is coated with a transparent insulating coating which needs to be burned off when soldering. Make sure the tip of your soldering iron comes in contact with the wire when soldering it to the PCB to make sure the clear layer is burnt off.

      1. By the looks of this model the wire doesn’t look like it was soldered before it just looks like it made contact with the solder blobs.

        So we’re saying this was soldered and should be resoldered whilst ensuring the coating is burned off?

        Thanks for the speed reply. – You’re an ace website doing customers proud – Lets fix and not throw away, lets not be ripped off and add more crap to landfill 🙂

        1. Yes it would have been soldered in place. As long as the soldering iron tip makes contact with the wire you can assume that the coating has burned off. Well done for trying to keep more electronic waste out of landfill!

  15. Hi,
    I have managed to change the battery on v2 model, checked all the copper wires were in tact. I have a red light which flashes for a couple of seconds which would indicate to me I have connected it properly! and then nothing. Any suggestions please

    1. Have a read through of our trouble-shooting tips here. It might just need to be left on the charger for an hour before it acknowledges that it’s charging.

  16. Hi,
    I changed the battery of my Oral B 7000, When I received the new battery it showed 0.02V.
    After 6 hours charging it’s now at 0.95V but still no light on the brush and it won’t start either. Is it normal ?
    Regards

    1. That voltage is a little low but the battery might just need to recondition if it’s been stored for a while (several full charge/discharge cycles.) Check your soldering and the coil wires as per our support page.

      1. Thanks,
        Soldering and wires seem ok, they should be since the battery was charging, right ?
        I left it charging for the night and this morning it was at 1.02V It seems it’s bottoming out (0.3V in around 15 hours) ??

        I can’t do a discharge cycle because the brush won’t turn on.
        should I buy another battery ?

        Regards

        1. The brush can appear to be charging even if there’s a fault with the soldering or a broken coil wire. However, if you’re sure these are OK then perhaps the battery is faulty and one of our GP or Varta batteries will get you up and running.

  17. Very useful step by step guide.
    And very kind support from your site.
    I got the battery 5 days after order was done.
    Replaced it with the perfect guide.
    Thank you

  18. Has anyone come across issues with the toothbrush not being waterproof after replacing the battery?

    1. The seal at the top is fully waterproof once the ring is refitted, so you shouldn’t have any moisture issues. For storage advice see our electric toothbrush care tips.

    2. My tootbrush is not waterproof anymore after replacing the battery. It leaks down the shaft from the brush head. It started one week after replacing the battery the tootbrush was turning itself randomly on. The first time it happened in the middle of the night. It fell off the bathroom sink in our en-suite giving us a mild heart attack.
      The workaround so far is to remove the brush head as soon as the brushing is finished, dry the shaft with a towel and store it horizontally. Would you have any other tips?

      1. It’s possible that the innards weren’t pushed fully home when reassembling the handle. Check that the ring is fully seated too – you can warm it in very hot water before refitting to give it a bit of flex. Other than that, like you said, store it on its side. We have some other toothbrush care tips here.

      2. exactly the same with my toothbrush! I opened it again to dry it, unfortunately it doesn’t work now. The battery leds are completely off, as well as nothing happens when pushing any button (either power and/or arrow down).
        Any step-by-step procedure to check where the fault is?
        Thanks.

        1. Claudio does the charging light show that the battery is charging when it is on the charger?

  19. Hi,
    I bought from Amazon a battery 3 months ago, it worked well at first (1 complete week without charging) but after 2 months : completely flat after 1 use.
    I thought it was the chinease battery so I bought the one advertised on your website (varta) and installed it this saturday. I let it charge until the brush was completely charged but the brush only lasted 2 uses. And now, it won’t even last 1 use !! (the battery is 2 days old. )
    How is that possible ?
    Regards

    1. Hi Stephane, it sounds like you’re suffering from one of the common issues that crops up when changing the battery. Take a look at the trouble-shooting tips on our customer support page here. It’s likely to be a broken coil wire, your soldering, or that the meter needs a reset.

      1. Hi, Thanks for the answer.
        I let it charge for 24h yesterday and this morning let it on until it stopped : it lasted 2 minutes.
        I dismantled it again and double checked the soldering and coil wires, everything is fine.
        I then tried the 10 seconds method, the brush lasts around 5 secs before it stops. Did it 5-6 times. then multimeter says the battery is at 1.442V
        Not sure what’s wrong here really ?
        Regards

        1. The voltage reading indicates that the battery is fully charged. Try running the toothbrush with the handle casing removed in case there is debris jamming the gearbox. The only other suggestion is to check for short circuits caused by blobs or whiskers of solder on the PCB near the motor and battery connections.

          1. the casing was already removed during the whole process. Battery is still charging and indicates 1.483V now. I can’t find anything wrong with the soldering 🙁
            Regards

          2. Perhaps there is water damage to the motor or PCB from a leaking seal.

  20. Hey!

    You prepared a great guide. It was very easy to swap the battery on the Triumph v2 model.
    Unfortunately I have the same problem as stephane… After the swap, the battery can only run for max 3min, even though it has 1.4v. The toothbrush can’t even run longer if I connect an independent powersource instead of the battery. It seems that I could have a problem 5 or 6 from the Customer Support. I will discharge it using the cycle described in point 6, but I wonder if there is any other way?

    Best regards,
    Von_Watchmaker

    1. Yes the battery meter in the toothbrush can get out of sync with the new battery so needs resetting. With your Triumph v2 repeatedly trying the 10 second charge-then-run trick should reset the meter – there’s no easier reset method that we’re aware of! Customer Support page here.

  21. Hi,

    Could you help me?
    I repleaced my battery. After its installation I tried to test it. The red LED was on for a very short time, when I pushed the ON button, than nothing. The tootbrush is totally dead. It does not work and there is not any lights neither.
    I have checked by voltmeter, the charger coil works well, it can recharge the new battery fully.
    What can be the root of the problem? Is there any solution?

    Best regards,
    GN8

  22. great guide.. I replaced the battery for my Triumph 7000, now I can see the lights while charging. the first charge took around 20-24hrs. after fully charge I remove the toothbrush from charger, test it for couple seconds, seeing battery level is 3 lights, and then I put it on desk. by the time I want to use it (4-5 hours later), the battery it totally out… not even able to get the power level light up…. is it something wrong with the board? not the battery itself?

    1. Hi Tom, take a look at our troubleshooting tips page and see if those checks solve your issue.

      1. thanks, I am trying the re-calibration tricks now.. but one question, how can I know if the battery is truly empty? by doing the 10-second thing, I noticed that some times it will run for a long period, like 60+ seconds, some times it won’t even power up… it’s confusing when the battery is truly empty.

        1. It will probably be empty when you start to see consistency after a 10 second charge e.g. it might run for 2 seconds then stop. Same result after the next few 10 second charges.

  23. Hi, just completed the battery replacement for my Braun Oral B type 3764.
    It was completely easy to do, just needed the right tools, a solder sucker and a fine tip soldering iron was borrowed and the instructions you provided were detailed and easy to follow.
    It means that I’ve not thrown my toothbrush and it will hopefully last me for many years to come,
    Many thanks.

    1. Great work! It’s good when you can borrow the tools too.

  24. Hi. Many thanks for a nice guide! I too, managed to snap the charging coil wires when diassembling. I have not found any guide that would fit this model, but it seems obvious enough that the two wires coming from the coil are to be soldered to the corresponding tin lumps. However, there is this weird 3rd wire of ~2 cm, that also is likely broken. If I solder it where I think it might go, it does not make any sense. It is now soldered in one end to one of the tin lumps. There is a piece of same type of wire next to the other lump, but it is not quite connected to it but just takes a few rounds around a plastic nob. Actually it touches the tin lump, but I guess it should not connect as it should have the isolation on. The lenght of the longer piece is just enough to connect it to this shorter piece, but I see no sense in it. If the shorter piece does not connect to the tin lump, then this is just a loose piece of wire leading nowhere, and if it does, then the too wires of the coil get connected and then it does not quite work.
    I would be very grateful of any ideas.
    Best
    Jyrki

    1. Hi Jyrki, the two pieces of copper wire that wrap around the plastic posts can be removed if they are loose. During manufacturing and before any soldering they were the wires from the coil, wrapped around the plastic posts. Then each wire was soldered to the PCB. If the wires snapped then the pieces wrapped around the plastic posts can be removed.

  25. Anybody know a service that will do this replacement work?

    1. Whereabouts in the world do you live? Have a look at our toothbrush battery replacement service page.

  26. Not sure what is going on,but here’s what’s happening.
    (1) Replaced battery and pressed power button,nothing happened.
    (2) Put toothbrush on charger and it starts blinking.
    (3) After a while,two leds are lit up,so I tried the power button again,nothing.
    (4) I hit the power button while still on charger,and it starts up and the bottom led is blinking red. It won’t turn off unless I put it back onto the charger,don’t even have it hit the power button.
    (5) Try the power button again,and nothing.

    Any Ideas?

    1. Have a run through of our troubleshooting tips. It sounds like it could be a short circuit, loose connection to the battery or a broken charging coil wire.

  27. Hi, last week completed the battery replacement for my Braun Oral B type 3764.
    The toothbrush works fine, the charging is ok, but the toothbrush cannot communicate with its Smart guide unit. I tried to pair them as I read in the user guide, but it does not work. Any idea? Maybe I wasnt cautious while soldering and the radio chip got too much heat?

    1. It’s possible that the radio chip got overheated/moved/shorted by solder. Also check the user guide because you might also have switched off the radio function in the toothbrush.

  28. I have already turn off and on the radio, but it doesnt work. The led is lighting on the toothbrush but it cant connect. Could you show me which one is the radio chip and where are its connections?

    1. Sorry, we don’t have any schematic diagrams or parts lists. Check for stray blobs/whiskers of solder that could be causing a short circuit.

  29. Thanks to the Ionic video and step by step chart I have replaced the old battery with new. Before I complete the re-assembly I want to know if there will be a problem if the spring touches the positive terminal of the battery? Please advise.

    1. As long as there is still the plastic spacer between the motor and the spring, then it does not matter if the spring touches the positive tag or terminal of the battery.

  30. Thanks for the great instructions. I had a replacement battery installed. There was no response from the toothbrush (lights or brush movement). Is the unit dead or is there a chance that putting it on the charger will get it going? Thsee results were at the repair shop. I didn’t have the charger with me. I am thinking of trying it again and bringing the charger in next time. Your thoughts?

    Thank you!

    1. Hi Jerold, verify that the solder connections to the battery are still intact, and that the fine copper wires from the charging coil to the PCB are not broken. Definitely put the brush on to charge for 2 hours – you should then get some response from the motor/lights.

  31. Hello.

    First of all I find your tutorial really great;))

    I write to you from France so my English is not perfect.

    I search for my part the head of the toothbrush because since can a black liquid flows from it (I think this is due to wear)

    This piece is it for sale, can we buy it, I did not find it …

    Heartfelt thanks.

    1. There are no spare parts available. The liquid could be old toothpaste and water. If there is liquid inside the toothbrush you can remove the internals and let it all dry out for 48 hours. Then reassemble the toothbrush.
      Every time you finish brushing your teeth remove the toothbrush head and store the toothbrush horizontally.

      1. Thank you for your fast response.
        I will try to disassemble the toothbrush with your great tutorial
        Thank you very much.

  32. Hi, the instruction video as well as the pictures were easy to follow and I replaced my battery within an hour.
    The problem I’ve experienced was that the seal near the brush was leaking water which in a weeks time slowed the speed dramatically and the red lamp was on constantly. Re-opened the case and it was wet inside. Let it dry and greased the cogwheels as good as I could , re-assembled and put silicon instead of the little plastic ring.
    It works perfectly fine right now!
    Maybe silicon couuld be added to the instruction?

  33. I am trying to replace the battery on the Oral-B Triumph V2. The guide is fantastic.

    After following the guide, I can charge the battery and get a flashing green light. If I leave it on for 12-24 hours, I actually get 2 and eventually 3 flashing green lights, indicating a good charge. However, when I push the button to start the toothbrush, it flashes red and does not turn on. If I put it back on charger (even if it just had 3 green lights) it appears to start charging over at one light.

    I’ve taking the handle apart again and checked all pieces and everything seems to be in place (I even resoldered to get some nice shiny joints). Any idea what could be going on?

    1. Hi Jeff, it could be the charging coil connections. Have a read through our troubleshooting tips and if this still doesn’t help and you’re able to measure the battery voltage let us know what that is.

  34. Great guide, thanks!! The problem that I encountered was that the replacement batteries that I purchased have tabs that are very difficult to solder to. I tried pre-tinning, lightly sanding, flux, etc. Finally, I snipped off all but about 1/2″ of a tab, then wrapped the remaining metal of the tab around one end of piece of copper wire (22 gauge). I used needle nose pliers to make a strong mechanical between the tab and the wire, and then soldered the joint. I repeated this with the other battery terminal, fed the copper wires through the holes in the circuit board and soldered them to the pads on the board. The copper wires were very easy to solder down, and the unit charged up overnight and works well.

  35. I replaced the battery in my Oral-B Triumph V2, charged for 24 hours then tried it. It turns off after the first quadrant, when it should signal with one vibration. I read the troubleshooting, and tried to leave the toothbrush running until the battery got empty, but it turns off every time after 30 second, before it can vibrate once. It would take a week to get the battery discharge if I’ve to start charging again for 10 seconds after 30 seconds of running. Is there an easier way to get the battery empty?

    1. If your toothbrush shuts off after the first 30 seconds of the timer then there is probably a stray blob or whisker of solder causing a short circuit on the PCB somewhere.

      1. I took the brush apart again, but I can’t see any visible blob or whisker. Do you have any idea where should I look for a short circuit?

        1. No, just around the areas where you soldered. It could be also be a damaged component, or water damage to the PCB 🙁

  36. Great guide and website!

    Im interested in reaplacing my battery with a low self discharge, like an eneloop. Do you sell these?

    Also, is there any reason a standard AA NiMH (with tabs) can’t be used?

    Thanks!

    1. Thanks! Low Self-Discharge types are not relevant for toothbrush applications because in a toothbrush the battery will be run down through use after a few weeks. Standard Ni-MH cells will not self-discharge by any significant amount during this period. LSD types are designed for applications where the device will be charged up and will then be unused for many months or years, or for low-drain devices where you will only be charging it up about once a year.
      AA size batteries won’t fit in Triumph toothbrushes without modification of the toothbrush, and if you want to modify then you may as well upgrade to one of our high-capacity 2700mAh Varta batteries (49mm long). Hope that helps!

      1. Thanks for your reply, much appreciated!

        Can you provide a link to the 2700mah batteries you sell? I can only see the 2500mah GP ones. Also, do you sell any soldering irons? It’d be a great addition to your shop if you sold an ‘all in one’ repair package!

        You guys are doing a stand-up job!

        1. You’re welcome! The 49mm x 17mm 2700mAh Varta battery is available in our shop here.
          Good suggestion about the soldering irons, however, they’re too bulky for us to dispatch. If your local electronics shop doesn’t have one you could try your country’s Farnell/element14 website or amazon/ebay. You might also find a that a friend/relative/colleague has one you can borrow.

  37. Which is the best replacement battery option from your store for type 3762? GP or Varta? I would have chosen Varta but tags seems a bit short, judging from the pictures…
    Thank you.

    1. At the moment we’re stocking an FDK battery for a Type 3762 fitted with a 42mm long battery. These are made in Japan and are the best quality.

      1. Sorry but English is not my native language, “stocking” means that FDK batteries will be soon available? If they are already available I did not find them, please point me the product page. Thank you for your help!

        1. Just click on the words “FDK battery” above ^
          They are available to buy.

  38. Thanks for the guide! I’ve just replaced the battery, and the toothbrush charges fine without the bottom cap (the cap that is removed by screwdriver in the instructional video). However when this bottom cap is on, the battery doesn’t charge. Any ideas?

    1. One (or both) of the copper coil wires is probably broken between the coil and the PCB. Check the wires including where they are soldered to the PCB.

      1. Turns out the problem was with the charger, swapped it with a new one and it charges fine. In a separate issue, when putting the final top ring/seal in place, water got inside and now the tactile on/off switch doesn’t work and the toothbrush turns on randomly. Will try drying it out and using some CRC.

  39. Hey,

    first of all, thanks for the good guide.

    But i have a small problem. I´ve done all steps and everything ist working.

    The Battery is charging and the green lights are flashing.
    But it needs more than two days till it´s fully loaded.

    After 2-3 minutes of brushing it loses all battery loading and falls from 3 leds to 1 red leds and finally turns off.
    Battery is brand new is there something more to do, or is my new battery simply a DOA?
    Maybe a faulty charger?!

    Greetings
    Daniel

    1. Hi Daniel, carry out the checks and tests on our customer service page.

  40. Hello all,
    Just replaced the battery.
    All looks fine but doesn’t charge(blinking red). However when placed upon a different charger(not oral B, other company) charging begins (green light).
    replaced the battery because it lasted for 3 days and then dies (from 3 green to red) at once.
    But the old battery had 1.14 V inside as compared to a new one 1.24V.

    Is it the charger or the battery or else? Has anyone encountered this before?

    1. That’s a strange issue! It could be a bad connection inside the toothbrush such as a copper charging-coil wire is broken or a dry or broken solder joint. Carry out the checks and tests on our customer support page.

  41. This is the second time I’ve used this guide to replace the battery in my Braun Oral-B Triumph v2 (3762), the first time I used a NiMH battery from RS, and this time I bought the Varta battery directly from this site.
    Very easy to follow this guide, and it was very quick to do the second time around, my thanks to you for helping reduce needless environmental waste!

  42. Replaced and all was working for a few weeks then the toothbrush started to slow down. i persevered but it seems yet again the top seal was leaking and now the brush wont do anything – completely dead.

    I think you guys need to come up with a solution for the seal near the toothbrush – maybe sell these if you can source copies?

    I’ll let it dry out but tbh I think mine is now dead 🙁

    1. Hi Scott, Once you’ve opened up the insides and let it all dry out it should start working again. Always store your toothbrush on its side with the head removed between brushings. This stops water running down between the metal shaft and its plastic surround. We have some toothbrush care tips here.

  43. Dear All,
    I have a brand new Braun Oral-B Triumph v2 Toothbrush, but it doesn’t charge. The warranty is expired.
    When i push the power button it starts flashing red.
    I decided to change the battery, but the charging light doesn’t start to flush green.
    May be you have had a similar case.
    I would appreciate it if you would help me to fix it.
    Thanks in advance.
    I am looking forward to receive your reply,
    With my best regards,
    Ivo

    1. Hi Ivo,
      Sometimes it takes an hour or more of charging before the green charging light starts to flash.
      What is the type and input voltage of the charger? Do you have a friend with a Braun Oral-B charger that you could use to check the charging of your toothbrush?

  44. Hi. My toothbrush is around 8 years now and I’ve brought it back to life, thanks to your amazing easy to follow tutorial. I also snapped the copper wire but managed to unwind and re-solider.
    My only problem now is that our toothbrush magically turns itself on in the middle of the night! It’s happened about three times now! Any ideas why this is happening? Guessing I should be worrying – as ?? it could be a fire risk?!

    1. Good to hear about your successful repair! It sounds like water might be getting inside your toothbrush. Open it up and let it dry out in a warm room/cupboard for 24 hours. Make sure the sealing ring at the top is put back into place correctly. Then have a read of our toothbrush care tips to help prevent it from happening again. Hope that helps!
