A NEW BATTERY FOR MY ORAL-B TOOTHBRUSH

perfect! worked for me!

So all of them have same motor type ?

Nice !.

How to kill the 30s timer? I'm done with cleaning when I am done, not when the timer says it.

Thx man

Why was there no battery in it when you first took it apart? Am I the only one to notice?

Wow, doing the 500 model is much easier.

Great Job, now I can change my Toothbrush battery following your video, thanks so much. Tip: keep your soldering iron tip clean and shiny for better soldering. Me, 45 years experience electronics engineer.

<hi, i undertook this project today, think there were some shortcuts in your video, but overall ok.
I replaced the battery with a standard amazon basics 1.2v rechargeable ni battery ca 1.2EURO piece which i had lying around.
It fits if you remove some plastic with a cutter in the battery holder... solder the leads of old battery to new.. for the rest same story as in the video.
Use flux to ease soldering. and.... scratch the battery before putting a blob it soldering tin on the battery...
The plastic piece on the top, don't bother .. push the whiole thing in from the top, remove the plastic cap is you want to clean it, and push all back from the bottom... the plastic on top is flexible and this method is simpler and leaves less traces... I wanted to complete this operation with less soldering, but its not possible... you need to use a soldering iron...
Pitty but true
Good luck to you all, this work can be completed in 1 hour, not worthwhile unless you have time and appropriate tools.

about half way through this i'd love to see him put the 'carcass' down and pick up a two pound maul and, seal it up. That's complicated like a sounding rocket experiment.
But, thanks for the vid. you did amazing.

Thanks for the video! Is there a trick to put on the sealing ring on the top?

what is the battery model?

Блин это очень сложно 😞

Braun could have just made it changeable…

very good… where do you have your studio?

No sound on this video wtf

18650 battery?

Thanks for this great video (it confirmed that replacing the battery was not something I was prepared to tackle).

What type of batteries it used

I almost broke the wireless charging pad, trying to open the toothbrush as described. Not mentioning that you opened the back side before, by other means, is just stupid.

how model baterry inside?

All that?! To put a battery in? What if I can't assemble it back? Smh

You were dead lucky. The heat from your dodgy soldering iron could have easily wrecked the circuit board.

Well this is insane. But good video.

This reminds me of working on the wife's Audi. Beautifully designed but with the omission of maintainability as a design goal. "Step 1: Remove engine....".

This is a great tooth brush

Thank you so much

Thank you! I watched a number of videos before I came to yours. I wasted a lot of time! Yours was the best---disassembling the various components and then soldering only what was necessary. My first one took awhile but the second one went very quickly! Thanks again!!

Braun are swindling bastards, making it so hard to change the battery, that most people will buy a new toothbrush. This is a sharp practice that ought to be outlawed, as it's also a waste of this planet's dwindling resources.

Watch out for the tabs on the replacement batteries. I did this same operation on a Braun shaver. The tabs on the battery were too wide to fit through the holes in the PCB and it was a real pain filing them down.

Thats a lot of pain - Rather than tinkering around, i think i'll just buy a new one.

Have I gone deaf or has your mic failed you?

typical German...over designed....over engineerd over priced non sense.....this could have been designed to change the battery very easily....but will German tecknockrasy alow that to happen ....nooooooooooooooooo lets make it diffucult to repair...no wonder they lost the war....twice. Only the Germans could invent a wheel barrow that would be a nightmare to fix....

CHECK THE POLARITY BEFORE YOU REMOVE BATTERY.

You just gave up on sound completely.

Thank you. My brush was not charging anymore. The battery was okay but there was rust on the mainboard, which caused a short circuit. Took just some cotton buds with pure alcohol to fix it ;-)

thank you :)
