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.
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....".
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!!
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 ;-)
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.
@@johnyoung5392 soldering !! Now that rejogs my memory back to the 80s when i was a school boy at secondary school. I did a fair bit in our electronics module
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.

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

Thank you, good idea!
This is a great tooth brush

what is the battery model?
Well this is insane. But good video.
Thanks for the video! Is there a trick to put on the sealing ring on the top?
I've heard use a second brush head
Why was there no battery in it when you first took it apart? Am I the only one to notice?
No you weren't the sole one.
how model baterry inside?
Braun could have just made it changeable…
Specially as it lasts one/one and a half years, even in their costlier models.
"Hopefully", someone could sue them one of these days...
Wow, doing the 500 model is much easier.
Thats a lot of pain - Rather than tinkering around, i think i'll just buy a new one.
wow, I dont even have solder to do this.

The regular household would not have a soldering iron. Gimme a break
@@Texaspoppy whats it to you. It was just a statement - that the term soldering reminded me of when i was school.
What type of batteries it used
perfect! worked for me!
So all of them have same motor type ?
How to open Oral-B PRO 3 3500 Typ 3772?
Thank you so much
❤❤❤
very good… where do you have your studio?
Nice !.
They burry the AA sized cell inside the housing and solder all around so no one can replace it. Must buy a new brush.
thank you :)
All that?! To put a battery in? What if I can't assemble it back? Smh
You are only doing this once it won't charge anymore and you are left with either throwing it away or trying to replace the battery
18650 battery?
No for sure
You were dead lucky. The heat from your dodgy soldering iron could have easily wrecked the circuit board.
Thx man

Have I gone deaf or has your mic failed you?
Блин это очень сложно 😞
