This is probably one of the best, most professionally done instructional videos on youtube. The detailed explanations and great photography are what everyone else should aspire to. Thanks!

worked! 40 minutes for reviving 2 toothbrushes..... thanks for this comprehensive video! compliments!!!!

Perfect ! I change the battery of my toothbrush 2 days ago and for now, it works well.

Perfect - new lease of life for our toothbrush - the only suggestion I would add is to warm the up top sealing ring in a glass of hot water before pushing it into place. Thanks so much for the video.

Replacement worked well thanks to your instruction, thank you very much. About half an hour of work. It's now on the charger; have to test it more though.

Great. I replaced the old battery after your demo and all works. Subscribed.

Thanks to this brilliant video tutorial and all the positive comments I can now no longer justify splashing out on one of the fancy new models! 😥 I'll be placing an order for a new battery shortly. 😃

Worked for me thanks. Tip 1: I needed a "desoldering vacuum pump" to get the old battery desoldered. Tip 2: I heated up the ring in hot water again to get it reassembled at the last step.

Your explanation was very easy to understand. I appreciate it. Thanks to that, I could repair it.

Great tutorial, thanks! After some time the contact of the battary due to the fall damage had been ripped off. Replaced with the wires, to avoid such a situation.

Worked like a champ. Thanks for posting the guide!

thank you managed to swap out the battery following this guide however broke the stainless tip during the process... Now the brushes wont stay on!. Looks like a new toothbrush is on the cards! Thanks anyway very informative.

Thank you very much for all that USEFULL information. Pity it's a slideshow rather than normal video review.

Cool! I would never have thought the base acted as a screwdriver, in essence. Cheers

Terrific! I spent€10,- to repair 2 Oral b Triumph 9000 brushes ! Took about 10 mins each was a nice job, with great result. Thanks for a clear guide on the fix! Sad that Oral B doesn't offer this as a service :(

Excellent instructional video thanks. Thanks too for the super-quick delivery of the replacement FDK battery!!

Thank you! Some doubt about "everybody can do this", but i was able to...it takes some time but you could do that!

Very good instruction! Thank! I replaced the batteries of two brushes, the first was easy, with the second I was silly enough to mix up plus and minus, shame on me. I noticed that it became hot (the battery was not that full, when it came) so I fastly solded it off again and changed the side, now it works, I was lucky. The batteries was near 9.- euro one piece, I hope the brushes run again a while now. One brush had a bit broken seal at the top, I put silicon around it, hope its sealed now.

Thank you. Excellent instruction. I used an AA eneloop 2000mah Ni-MH because of availability. It is longer so the plastic near the positive had to be cut away and the steel spring replaced by a thin insulating packer. It gives 14 days = 56 minutes per charge. Excellent.

Nice tutorial. Thank you. Just changed my battery!

Thanks for creating the video, it worked great!

Thanks buddy managed to revive the brush saving it from landfill and my pocket too.👍🏻👍🏻

Many thanks. I save a lot of money with this video.

Great instruction and service. Thank you.

Aku wymienione zgodnie z filmikiem. Wszystko działa. Dzięki.

Grazie mille!ho appena finito di ripristinare il mio con appena 12 € è un po’ di manualità!grazie questi sono i video che amo.

Thanks for your guide. I have placed an order for a replacement battery

Worked perfectly! Thanks

well done with the photos and text, thank you, just ordered

Danke, sehr gute Anleitung :D

Thanks for a great post it worked for me I did use a 10mm socket to push the ring back on at the end 👍🏻🍺

Know this video is old now, my toothbrush battery just died today (very '1st world" problems having a fancy electric toothbrush to start), but now I can try to replace the battery instead of throwing it out. Thank you for taking the time to do this.

Thank you worked amazing prying the top tap off was hard and also bending the tabs was tricky and getting the top tab back on. But thank you so much for the video my toothbrush works again and charges.

Thank you! Worked for me.

Awesome! Thanks a lot! Would have scrapped my toothbrush without your video.

Amazing, thanks :)

thanx.. really helpful

Worked for me

Top Tip: The plastic ring is stepped so when prying it out you might need to push down into the soft rubber of the casing to get under the edge. Standing the brush in hot water beforehand will also soften up the ring.

As a total novice with a soldering iron I'm enjoying just the challenge of this. Beware! be very careful when locating the catches before removing the innards. There are catches-within-catches that locate the induction coil to the circuit board. If you release these and then apply any force - you're likely (as I did to break the connection to the CB). You must be sure to release the outer catches - see the image at 1:47.

you genius, thx a lot

Excelent!

Nice one for the tutorial. I've hooked everything back up, and it powers up. But the shaft doesn't rotate anymore 😞

it works :-) thx

Followed the instructions for the V2 ... Following the replacment I get flashing red and green lights but no charging nor will the motor work . I've read that the unit needs a kick / jump start by connecting the + end of the battery to somewhere on the unit but no more instruction than that .... anyone any ideas ?

Thank you for terrific instructions! But hey- what is "hot water"? Boiled water?

how much do you charge for repairs?

Thanks. Good tutorial. I just have a few questions: Why do you have to soak in hot water first? Also, the small promontory on the charger doesn't fit the depression on the plug, so how is it supposed to twist the plug off? Will opening the handle actually destroy the unit, as the manual says? Will it ruin the waterproof quality of the unit?

What function does the spring and spacer serve ? It doesn't hold the battery as its held in a holder and soldered. Does the spring act as an electrical contact as its touching the positive battery terminal

Great video but I have a problem. When i opened the bottom of the Oral b Type 3764 I damaged the loading coil. Am i able to repeat this somehow? When not where can i buy a new one?

Didn't have to remove TOP. Instead soaked BOTTOM, placed onto stand, barely turned it and the end popped off. Then the top, turn upside down, press top "point" onto table/counter top. Press firmly; not hard; insides pop out (of the bottom, which is now the "top"). Anyway, this worked for my model 7000.

I just tried this process on my Triumph V2, which will no longer hold a charge. Unfortunately, I was unable to successfully replace the battery after following the procedure in this video. The ring at the top of the unit refused to budge, even after 5 soakings in hot water. I was finally able to remove it after several minutes of exposure to a heat gun at high temperature. I had similar results with the base, which also refused to budge after several soakings in hot water. Unfortunately, the heat gun managed to ruin the base, so I did not proceed any further after that. I might add that this is my second attempt to replace a battery in a Braun toothbrush, and my first one was not successful either. In my opinion, these devices are carefully designed to prevent easy battery replacement, and I won't by trying it again in the future. I'm just now waiting for my new Triumph to finish charging.

Any tips for water damage ? ... Mine has stop working and after I open, there was some humidity .

Hi, I replaced the battery and everything works. But after one day of toothbrushing I've noticed that there gets some water into the toothbrush .. I seems that the ring on the top is not waterproof any more. Do you have a hint how I can make the ring waterproof again? Maybe using some silicone or something?

My type 3762 needs a new battery, its 42mm long X 16.75 dia / Whats the part number? (it's hidden underneath @ present) and I would like to get a replacement before desoldering.

Hello Is oral b pro 6000 smart series’ battery can be changed with same way. Apart from that your channel is very good. Thank you very much

I have changed the battery of my Oral B 5000. The toothbrush works but after only 1 minute of use it turns off. Even if I have totally charged it... So I have to re-charge. Could be an issue of the battery?

Can you mod the 42mm battery toothbrush to take the 49mm battery? I noticed the plastic spacers and was curious.

Is there any way to tell which battery I need before dismantling the toothbrush? I still want to be able to use it until the replacement is delivered! Thanks.

Slight problem. Battery charging without end piece on bottom (part where screwdriver needed to pry off bottom). Battery does not charge when I put the bottom piece back on, Any ideas?

Fixed as well! Took me a while to get the battery off, also I cut the charging connectors by mistake! Careful.. they are very fragile! A re-solder made everything like new ok. Thanks!

I'm going to ask this question: where can you get the soldering iron and parts that you're referring to? Is this something easily available at, say Radio Shack?

Which battery would be easier to install for the 7000 Pro?

Can you also supply better LI-ON replacement batteries? NIMH is 90s technology.

Anyone know what battery size to order for the Triumph 5000/3862 purchased in UK?

have changed the battery, charged it up but it will not go? is there a reset procedure ?

Hi, i have done as your video but the battery upon charging does not hold charge and goes back to not working? It charges as i can see that happening, but as soon as i take it off the charges, it does dead. Any ideas?

What's the difference between 42 and 49mm? If I buy 49mm will it fit my V2 or not?

Hi there! Great and useful video. Short and to the point. I see you have different options on the battery itself. Can you tell me the actual differences between them? Æ

is my toothbrush still waterproof after battery replacement ?

grazie, almeno ho capito come smontare , poi vediamo se riesco a non distruggere tutto

My 3762 stopped working. I don't know if it's a battery problem because when I turn it on it seems it doesn't have enough power to move the brush but I can hear by the noise it is trying. Do you think it's a battery problem or another issue?

Hello everyone, I have an Oral B 3731, my friend soldered a new battery for me. But from now on this electric toothbrush won't turn on, My friend checked it with a meter and the motor of this toothbrush works. But the toothbrush button does not turn on the toothbrush and the battery charge status does not appear on the display. Can anyone help and advise what is the reason why the toothbrush does not want to turn on after replacing the battery?

It's ok to put a longer battery in this model?

Two things turned me off this replacement. Using a soldering iron and the fact the battery is NiMh and not Lithium. I went and bought a new toothbrush with the Lithium battery in it and top up charge about once a week. So much better than having to wait for a NiMh to discharge before recharging.

Hi, dont know if you see this: Everything worked just fine, battery is charging, lights are on when button pressed. The problem: No vibration! Dunno what went wrong, but I think I have to throw this expensive piece away :-(

Hi, I replaced the battery but then only bluetooth lights are flickering, when you charge it? No power at all, no battery indicator light as well. I might just burnt the e/board when desolder it. Is the board damaged? Do you have any idea what's happening?

if only I had a soldering kit.... and i know the soldering is cheaper to buy than new toothbrush

People of Earth, as for new batteries - any ebay/other-www with international shipping would be great! )

I'm still confused about how to precisely shape the solder tags

Good. but i just broke mine.

1

well my one broke into many pieces... :(

Not the Best way, should be possible to damage the contacts from the charging spool.

This video is certainly one way of getting a migraine

damn dude slow down a bit...

With out a solder?… stop and next video….

Too much work
