Great tech video, Binh does a great job explaining things to do and not do as he goes along. One suggestion to all DYI’ers. Take photos before you start and review before proceeding. The more the better.
Thank you for the guide! It helped me repair my Braun Triumph Professional Care toothbrush. The hardest part was to get the bottom piece off. Other than that, the process was pretty straight forward. The battery was so bad the the toothbrush could only do 1 cycle before it needed recharging. Now it's like brand new. It was also cheaper than replacing the entire toothbrush. But more importantly, they don't seem to sell this specific model anymore and I really like it. So I'm happy that I can now hopefully keep it for many more years.
Awesome video, I have the same one in your video! It gets maybe half a week on a charge, its getting pretty bad! Will 100% be doing this, thanks for the awesome video and sick lexus!
Cool! The most difficult thing was to remove the cap, the coil came off, but everything can be fixed! Thanks to the author, everything became very clear
This is beyond my capabilities. I did stage one. It’s pretty gross! But I will try the next steps. I wish it wasn’t so difficult to replace a battery !!
We need more people like you! I'm not sure if i can perform the changr from just the video, but the thought of throwing mine out or even ship back to "recyle" grosses me out!
Thank you for the DIY video to change the battery. A bit difficult because 1st time to open. Placed an order for the battery and hope I get it soon. Did not had those rust because it was still sealed tight and plastic frame. Mine had capacitors on the motor.
Thanks for the guide. I just wanted to see if there are any tricks to this before attempting. And a tip: I upgraded to a Vampire Solder Sucker with a silicon tip that you can mash on to the joint, it basically seals around the joint and removes solder in one pass most of the time. It's been a game changer. I 99% don't need wick and flux for solder removal now.
Replacement batteries are a bit harder to find for these now. I found one but the terminals were too big to fit through the slots on the circuit board. I had to cut them off and solder the terminals from the old battery onto the new one. A bit of a hassle but I made it work.
You make this look a lot easier than it actually is. Most of the time it's not worth trying to get them apart as it's a lot harder than shown here. Mine last for about 4 to 5 years so they go in recycling and I buy a new one.
Nice job with the video. I tried the 1/4 turn but the base piece got stuck into the opening that did not turn. Do you think soaking in hot water would help to loosen it that piece that is supposed to turn? The bottom of my charger says it is type 3757. Harry
I've got the Oral-B 9000/ Battery charges fine and no problems there but the shaft appears to be jammed, as the unit tends to hum rather than operate as normal. And ideas on how best to service the drive portion of the device?
Do you think you can make a video about permanently stopping the TPMS warning on the IS250? Mine has a super annoying warning that blocks the middle display
Looked at the link for the 42x17 battery and it looks like the solder tabs are offset in opposite directions. Is this an accurate pic? The battery I extracted, both tabs are offset slightly to the same side.
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?
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?
Typical German over engineerd , tecnology run amuk. this could have been designed to replace a battery easily.....but the Germans?? nooooooooooooo lets make so complicated hardly anyone can fix it.... my 3 month old toothbrush is garbage....
I hear you! I was contemplating doing it, but mine is about 12 years old, and I saw the level of corrosion of the one in the video. I’m just going to get a new one.
I found your video very useful. Unfortunately, it seems I wasn't careful enough on my very first solder attempt and it didn't work. Or maybe I needed to invest in better tools, instead of a cheap kit. The most surprising thing about your video was how you say the word "solder". I thought it was just you, but it isn't. I found other soldering videos and it seems all Americans pronounce the word the same, which is bizarre to us. The way we say it in the UK is just as it looks. It's the word "Sold" with "er" at the end. Great video though. Æ 👍
@@TunerwithKids Well, to be fair, we do say these words the way they should be said, considering the language came from here in the UK. As you say, Aluminium is another one. Look at the word. It's not spelt 'Aluminum' or 'Aloominum'. There is a letter 'i' before the 2nd 'u', which you Americans don't pronounce. Just like you pronounce 'Solder' as 'Sodder'. I do love the American accent, by the way... even with these minor annoyances. Æ
Funny thing, when I read "solder", I internally pronounce it like the Brits do, but when I say it out loud I pronounce it the American way. Then again, I also pronounce lingerie internally as "linger-ee" when I read it.
Mine is getting weaker by the day I hate to by a new set from Costco so I type it in. Here I am I hate to open mine up. I got two from Costco but one died long ago. I think I might take it apart the new ones are not cheap. Thanks for the video.

Kudos to you for repairing instead of replacing and cleaning up that corrosion instead of giving up on that one.
I'm too cheap to upgrade to new...LOL

throw away society for yall.
Like water suppose to get in there ?! Defective design or production if you ask me.

I went back and looked at the piece that you turned off-yours is round and mine is oval-so not being round it seems unlikely to turn.
Excellent video, very detailed!! Thank u
I’ve seen enough! I’m just going to buy a new one😆👍
For $100 and newer lithium ion batteries, get the new. This is old video so the NiCAD batteries are getting obsolete.
I've got the Oral-B 9000/ Battery charges fine and no problems there but the shaft appears to be jammed, as the unit tends to hum rather than operate as normal. And ideas on how best to service the drive portion of the device?
I think it’s seized. I had one go bad like that, just tossed it at that point
@@TunerwithKids ok cheers, and I'm assuming, happy Tet to you and family!
Thank you so much for this!
Do you think you can make a video about permanently stopping the TPMS warning on the IS250? Mine has a super annoying warning that blocks the middle display
Not possible.
Thanks for this great video! However, I would not use lithium grease on plastic! Silicone is the way to go. 10:58
Great point!

u found one with the "Z-tabs", you need U-tabs
excellent video and just like that I fixed it.
awesome video.. thank you for posting it.
What are the specs of the capacitor that you added? And what contacts did you connect the capacitor to?
I don’t remember but it was a very small uF soldered to the + and - terminals.

Does it charge? Maybe the switch or board got damaged.

Bad battery or bad motor.

It’s small, light, waterproof- goal wasn’t serviceability unfortunately
Consumerism … no design to repair. Buy. Trash. Buy. Trash. Buy.

I broke my charger when I tried the 1/4 turn :(
Wasn’t meant to be.

American accents. Just like how I’m confused every time I hear aluminum said in UK English.

@@BuddyBoy68 For the record, Americans spell it "aluminum," singular "i". We don't pronounce the second "i" because for us, it isn't there.
@@SteveN-bh3wv I do the same thing haha
Someone should tell this guy about the existence of desoldering braid.
I have that but its too tedious vs a vacuum pump. I use braid for final desolder cleanup but the vacuum is best for large clumps and liquified solder.
Flux is your friend. Never forget about flux, even when de-soldering. Flux and copper braid make life easier.
Mine is getting weaker by the day I hate to by a new set from Costco so I type it in. Here I am I hate to open mine up. I got two from Costco but one died long ago. I think I might take it apart the new ones are not cheap. Thanks for the video.
