This is the third video I’ve watched for this model . The LCD screen can be removed for easier battery removal and if you want the connectors intact for comparison when you are shopping for the battery replacement . Also the little top ring can be reassembled by pushing in with a 9mm socket . Removing the charging coil from the unit isn’t necessary ,I think that was noted in the voice over 😊. This is an excellent real time video and definitely gets the job done, thanks so much for posting 🤓👍
I will say that the gears needed a little lithium grease. That made it really fly and it is perfect to this day. Had this for about 20 years now. My dentist gave it to me when I became his patient.
Very nice work. I had to fix three of these, and in every case the top and bottom were stuck together with old toothpaste. Your video gave me the confidence to go after the shell with a vise to get the bottom off. The top ring was cemented in with old toothpaste, and I had to dig all that out of the ring channel, to make for an easy reassembly. I used a deep socket to push the top ring back on.
Better fixed than in the trash. I know my family is impressed by my ability to fix stuff. Nice to learn different electronic skills from a very experienced technician.
That's a long time for that battery. My Oral B is going on 12 years and I was wondering when the battery was going to need replacing. I guess I have another 10 years to go?
Very interesting. Last year my old Braun Oral-B type 4728 toothbrush died, same thing, battery didn't hold any charge, so out of interest, took it apart to see what's inside. While turning the bottom peace, somehow the charging coil got damaged, so it was lost case anyway. I guess otherwise I could've just replaced the battery like you did and still use it. Before I recycled it, took some parts from it, like the electric motor, which has metal gear in it, good one as most have just plastic gear. Also the rubber o-ring, spring and maybe some other small parts I have forgotten by now. I then bought new tooth brush which is using ordinary AA batteries that can easily replaced. I was thinking to use re-chargeable battery, but even regular battery seems to last pretty good amount of time as well.
My battery drains in 3 days now much quicker than before. I was thinking of buying new one but I guess I'll see on battery replacement. Had my Triumph for over 8 years.
I was fixing a slightly more recent OralB model recently. And it became a future project to finish 😅. I found out I also need to change the pushbutton switch and didn't have one that would fit at the time. Newer models are even cheaper, the cell is soldered to the PCB, no springs. And they are a little harder to take apart too. Made even cheaper if you can believe it 🤷
Well this one sold for something like 249.00 when new. I didn't pay anything, my dentist gave it to me complements of being a new patient when he was setting up shop as my old dentist retired.
@@12voltvids The one I still haven't completely fixed was given to me by a dentist too 😂. The profit margin on those must be incredibly high when you see their construction.
@@jamesbaker429 this one has a remote display as well that shows how you are doing and counts down the brush time. It was expensive back in the day but well worth it because 20 years later it still works.
I have changed battery in 2 different Braun Oral-B units, but without the sensor in the brush heads. Had to scrap another because it had leaked "toothpaste" and was a total rusty mess inside
Im surprised to see one of those toothbrushes still going. I replaced the battery in mine around 6 years ago, but after a couple of months the rubberised parts on the handle started to break down and go sticky, so I peeled it all off. Then it began to leak and was dead again for good after 6 months from corrosion.
Does the coil at the bottom to charge the battery have a diode to keep from discharging or not I can make a curcuit of a julethief to a 5v.please let me know.
Nice, good work! In 2019 I replaced my old Braun and got one that uses a lithium battery, maybe it lasts longer than the older one that used a nickel metal hydride battery.
That toothbrush is impeccably clean for its age. If you take one apart that isn't and where toothpaste has leaked inside, the smell will be from another dimension. 😅
You must have horrendous oral hygiene. I had an old oral B electric toothbrush that I took apart, the entire inside of it didn't have any area that wasn't caked in old toothpaste and water. I don't know how it lasted as long as it did. It made it a good 10 years... And mine didn't smell at all.
@@Jason-wc3fh My oral hygiene is fine. 😄 The cause of the smell was the toothpaste itself coupled with mold. The toothbrush never got to dry properly in my somewhat cold bathroom.
I always preferred the two stroke model. Darn emissions control legislation! Seriously though l had one of these but lost interest before the battery ever died. My Norelco rotary style electric razor though is another matter. Fantastic little device! Im only on my 2nd one in over 40yrs. I can tell the battery is starting to go. Won't be long.... I hope I'll be able to replace the battery when time comes!
@@12voltvids i agree it's no substitute for a blade. But l work on the road quite a bit. l find it's great for a quick touch up before an important meeting or show.
