Oral B Triumph Battery replacement Video
Well finally got round to doing a video on how to replace a battery in an Oral B electric toothbrush.
I have now changed the videos to include the correct way to unscrew and screw the back using the power adaptor . Thanks for your comments.
Straight forward when you know how to do it. I have only posted a video on youtube as a full blog post would be too long.
Using a “4/5 A” battery that I bought from http://www.component-shop.co.uk/ Which I think means it’s 4/5 the size of an “A” battery
You can check your battery against the chart in link http://www.powerstream.com/Size.htm This way you will order the correct one.
Some people in the USA have an “A” size battery which is 17mm diameter 50mm long..
Check first to make sure your battery is a 4/5 A , before you order , as not all models are the same. A “4/5 A” battery is 43mm long x 17mm
It can happen that the display will start cycling through the segments . It seems to be a test mode you can get in and out of this mode by pressing the smaller of the two buttons. The one that changes the speed..
Also note that when removing the internals be careful with the coil at the top as this is very fragile as the wires are very thin and can easily break.
Check out the video here.

Part 2
Your comments are welcome…

Your video is really top! Thanks very much! Very good description!
The battery from http://www.component-shop.co.uk/ was cheap, is easy to buy and send to Holland.
The + was only indicated by red colour and on the other side from the battery as on the video.

Wow – THANK YOU!
I have two of these at home and the batteries are nearly dead. I’ll give it a try – if it works your tutorial has saved me about 120 EUR! You should have a flattr-button in your blog!
January 19, 2012 at 5:56 pm
HI there,
Sure it will work and you will have fun doing it. If you have any problems just ask before you do it wrong..
Let us know how you get on.
BTW I will look at a flatter button..

Hi Nobby – great tutorial!
Just opened up the wifes Triumph 9000 (with smart guide) – the battery is definately 4/5 A size – but all it says on the outside is “Sanyo Ni-MH” and “333MV” – nothing regarding its voltage or current rating!
Do you think the 1.2V 2000mAh one used will be fine?
January 2, 2012 at 7:57 pm
Hi there,
mine is also the Triumph 9000 (with smart guide). If your battery is 43mm long x 17mm diameter then it’s a 4/5 A 1.2v and should be about £2.00 each from component shop..

Just to follow up….
Success!!!
I went the route of desoldering the battery tags from the mainboard – however the new batterry tags were a lot shorter! So i had to solder the old tags on and then resolder back to the board. Not ideal – but it did mean I had more room to solder the old tags onto the new batterry.
I also used a 1.8 mm flat-head screw driver to take the LCD off – worked fine and didnt cause any damage.
Thanks again forall your advice!

The instruction is great, worked without any problems with Triumph toothbrush #1, #2 will follow soon. Got the 4/5 accu at AkkuShop.de (or akkushop.com) who have also a french and german version. Type was HR-4/5AU, which has a bit higher capacity (2150mAh) than the original one.

I’m finding it impossible to take the bottom cover off. It seems to almost be sealed and I dont want to damage the toothbrush.
I’m guessing you opened and closed your one for the video many times before you recorded this video right because I cannot see how you are able to do this so easily. Am I required to damage the surrounding of the case to praise it open?
November 5, 2011 at 10:44 am
Hi there,
If I can remember the one in the video was only opened once before. so I guess yours is just tight. Try something flat and solid like a metal putty knife, metal blade or metal rule. but as it’s plastic there is also a change you will damage it slightly as it’s only plastic.
All I can say is don’t be scared and go for it as long as you have undone the bottom screw there shouldn’t be a problem.
Let me know how you get on..

Hi
Ok manged to get it open, and also to take the battery out. I bought my toothbrush from Boots around 2-3 years ago at Xmas. Looking at the size, I’m wondering if mine is the “A” size you’re talking about. Its about 48mm in length and about 17mm diameter. I check in Maplins and it looked as if the 4/5A was too small. I checked on the powerstream site, but doesnt seem to be listed?
November 7, 2011 at 5:48 am
The 4/5 left a ‘gap’ either end with mine? No problem. By the time
the clip is on, the battery soldered in and the spring replaced, the battery was quite secure. Inserting a physically smaller battery isn’t an issue, or wasn’t with mine.
HTH Dave
November 8, 2011 at 11:31 pm
@dpawson – The problem is by using a smaller battery, the capacity will not be as great. I see that in the US, you can get 2700mah A size battery. Am flying over there next week so might just order one to my brother’s place.
November 1, 2011 at 1:15 pm
excellent post! I just swapped my battery out, and it’s charging even as I type. I had to redo my soldering due to a broken solder the 1st time. But that was totally my fault for not checking my work properly, your described process was impeccable. I couldn’t find an “A” size online in DK, so I went with a 4/5A and it works fine. One way I could check if everything was properly done was that the LED panel immediately turned on (even before charging) with the “Empty – recharge” text and the animation of the plug shape moving towards an outlet.
Thanks again!!
November 1, 2011 at 1:11 pm
excellent post! I just finished swapping my old battery for a new one. I had to redo my soldering due to a broken solder – but it was totally my fault for not checking my work – your described process is 100% fool-proof (just did not count on this fool…..). I had a model which came with an “A” sized battery, but what I could find online in DK was a 4/5 A. It still worked fine and is charging even as we speak. I could immediately see if my soldering was correct because the LED panel switched on with the “Empty – re charge” text and the plug shape moving to an outlet. I did not get this on my first try, and I don’t know if every toothbrush does this. But this is one way to verify if everything’s OK.
Thanks again!

Excellent! I now have a fresh battery in my toothbrush happily charging away. For some reason the key in the bottom keeps springing out but it all seems secure. I’ll have another go at and see if I can fix that. This has save me a lot of money when the toothbrush itself is mechanically sound. Thanks nobbly noel!
For anyone else tackling this, you can remove the LCD with a T6 Torx driver, and solder the battery tags directly to the PCB which would be easier.
November 5, 2011 at 10:49 am
Hi there,
My LCD in not torx but a very small allen key about 1.5/2mm not something that is a a normal set of allen keys. I chose to leave the LCD in place as most people wouldn’t have the correct key.

My Triumph is from June 2007 and has to be charged every 5 days. So a new akku will have to be build in.
What do you think of getting a 4/5 A 1,2 with higher mAH than 2000? Would it help to expand charging intervalls? Or will it affect the ability of charging at all?
BTW: I will do a German Tut-Vid of me changing the accu – of course mentioning who taught me how to change the accu
.
November 5, 2011 at 10:52 am
Hi there,
Yes you could try a higher capacity battery but they are very difficult to find and it should give you more time between charges.
I have noticed that my new battery now is 1 and a half years old is starting to die. So what ever battery you put now will need changing again in about 2 years.

Whilst I am technically minded to do all of this (I fix computers as a hobby), I dont think I have the patience to replace my battery myself as I dont have the kit etc either.
Can I pay for you to replace my battery and post it to you? Also I would like to replace that battery with a higher mAH than the one supplied so that the battery lasts longer. Can you get a higher capacity battery?
Pls advise your email address or tel number if you are happy to do the above, thanks.

Being technically minded you should have no problem doing it yourself.
I don’t have time to repair other peoples brushes and if I did the cost would be the same as a new brush.
you can get a soldering iron kit from ebay for £4.99 including a stand and solder.
Get some patience and do it yourself. You’ll be glad you did.

October 4, 2011 at 4:51 pm
Thanks for the information, much appreciated.
I replaced batteries in two models, different ages?
The two taken out were:49 and 42mm long, both 17mm diameter?
The longer marked Sanyo, NiMH 224LH
The shorter marked 538MV SAN, NiMH.
Both 1.2v.
Of help to me. I soldered wire to the tags, pushed that through
the holes in th PCB, then soldered them to the PCB, since the tags
on the battery are too slender to stand much bending.
Also, note that the neg terminal is offset from the centre line
of the battery? Take care if cutting the battery tags to account
for this offset.
My replacement was as suggested, the 4/5A, from component-shop UK, which delivered them very promptly at a good price.

November 5, 2011 at 4:59 pm
Dave,
thats understandable from a company after sales point due to they can’t expect the average comsumer to start soldering. What they should have done is made the battery removeable and then sell you a new battery. I guess they want to sell more toothbrushes but what they are forgetting is that when your £100 product is thrown in the bin, will you buy another from the same manufacturer ?
September 21, 2011 at 5:47 am

Wow!! How can I thank you enough for posting this video?! I love my toothbrush and was gutted when I got to the point of having to recharge so often as the LCD screen would go from full to then showing 3 bars to nothing in 3 days!!
The video is great, so much so, for a woman who had never soldiered before was able to do this (well chuffed with myself!) and I love the bit when your little one started chatting to you – so cute!!
Many thanks again
September 26, 2011 at 6:38 am
Help!!
It was showing fully charged, then suddenly cut out dead after 3 days if use. I re-charged it over night and was showing full again. It then lasted for just over a minute.
Any help on what you think it could be?!
September 26, 2011 at 4:24 pm
Mary,
Very difficult to troubleshoot problems without seeing whats up but first check your solder connections maybe remelt the solder and get it nice and hot . It can happen that you have a dry joint it will look ok but not conduct electircity . After, if no luck you could try another battery.
January 8, 2012 at 11:13 pm
I just want to let you know that I recently got round to having another go at trying to fix my toothbrush. I re-soldered the points on 21st Dec. Charged it over night….haven’t had to charge it since!!! Result 😃
And it’s still showing 2 bars left!!!
Thanks for your suggestion of re-visiting my solder points (it was my first time at soldering anything!!). X
September 10, 2011 at 12:42 pm
Thanks for the tuition. Bought a 4/5 A NiMH 2000mAh 1.2V cell with solder tags for £2 and the exchange was a breeze. Thanks again…

Thanks for a great video.
I am not a diy person, but eventually managed to complete the process, however, this may be helpful to others struggling.
I could not get the first battery to work. Everything seemed OK left it to fully charge, but it kept immediately discharging itself when turned on. Tried several times to re-solder with no luck.
Tried a second battery and a slight variation on your instructions, left a about a quarter of an inch on the battery connectors, soldered as per your video then folded over the extra on the connectors and soldered again and it is now working perfectly .
Thanks again
August 1, 2011 at 7:14 pm
Thanks for the info and I’m glad you can clean your teeth again.
It could be that you and others had a dry solder joint which looks ok but has a very high electrical resistance that will cause problems charging.

Hello Nobbly,
I need your help and I am living in the UK
I manage to unscrew/open the toothbrush. I checked out the battery, the battery is slightly longer as I brought mine from the US. The size app. 16.5mm x 48mm. The website you mentioned regarding the battery is out of stock.
I have installed a normal AA 1.2v 2900mah NIMH rechargeable battery and I fully charged it but it only lasts few minutes, why? I have tried two different one’s already and it is the same.
Is there a difference in battery specification?
What I understand from your video is that the battery you installed is a 1.2v as well but what is the mah or is there a difference in battery specification?
Please help me your help is much appreciated.
Thank you
Zaman
July 25, 2011 at 7:03 pm
Hi there,
The battery I installed is a 4/5 A NiMH 2000mAh 1.2V so your battery should be fine but for some reason it’s not. Are your batteries Nimh type ?
You should take note of the original and try to replace with as near to original as possible..
PLease let us know how you get on…
nobbly
December 19, 2011 at 8:43 pm
Nice try with the AA battery but there is one more battery requirement for the battery besides voltage and capacity (mAh) and that is current capability (amps). The 4/5A battery contains more surface area and thus can deliver more amperage with less drop in voltage (needed for the power to drive the motor) than the AA. Therefore, even though the other specs are the same, the AA battery cannot supply the needed power.
June 7, 2011 at 5:00 pm
hi
whats the maximal length of the battery that will fit in the battery shaft?
thx!
June 7, 2011 at 6:13 pm
Sorry I can’t answer that. There seems to be different sizes of batteries depending on model and country. The best thing to do is take yours apart and see for yourself what battery you need.
nobbly
July 7, 2011 at 12:50 pm
I have installed it without soldering the tags. The way to do this is folding the tags from the toothbrush and battery inwards together and then creating a bend on the battery’s tag so it locks-in and does not loose contact. The tags on the toothbrush got to be long enough for you to do this.
July 8, 2011 at 4:20 am
HI there,
Thanks for posting a comment. Although folding the tags might be possible I would recommend you solder the tags to be sure to have and to keep a good contact for the future.
June 6, 2011 at 9:22 pm
Hi Noel,
Your video was very helpful. I ordered the replacement batteries (for two of these Triumph 9000 Oral-B toothbrushes. I removed the old, soldered in the new. They were slightly smaller in length than the battery that was in there, I’m in America, so maybe that’s why. The old ones were a dark green, the new ones a very light green — in fact, looked just like the ones you used in the video. Got everything back together. Once a new battery was in, the little animation went on, a moving plug indicating it needs a charge. So on the first toothbrush, just as you advised, I put it in its charging cradle and it indicated “Charging”. Ten minutes later I returned to check on it. Just fine so far, took it off its cradle, and it showed the first square lit (charged). Put it back on its cradle, while I continued work on the second unit. Got that one finished, and it also displayed the little plug-me-in animation. So I put the 2nd unit on the charger, and the animation continued with no change — the display did not change to “Charging” — the little animation just continues. Swapped the 1st unit back onto the charger, and it will no longer display “Charging”. Don’t know what’s going on… do you think the charger suddenly just quit? Logically, I can’t see why it would do that. This charger charges by induction, so even if I did have a short in the toothbrush(es), how could that harm it. I’m at a loss. Please reply with any ideas when you get the chance.
Gratefully yours,
Jeffrey Western
June 7, 2011 at 4:59 am
Like I answered in my post before just go back and check what you have done wrong. either that or try another battery. Don’r give up yet..
June 8, 2011 at 3:32 pm
Hmm, so you’re suggesting re-soldering… ok, i can try that… simply it’s strange that one of them would start charging, and then when removed and placed back on cradle, won’t charge anymore. Thnx
June 6, 2011 at 4:22 am
I completed the change and the display shows charging. But when I take it off the charger, the display goes dead and the brush will not turn on. Back on the charger, the displays shows charging again. Any suggestions?
June 6, 2011 at 4:04 pm
Hi there,
Sorry to hear that it’s not working as it should.
It sounds like the battery has either a bad connection or a bad battery.
First check that the battery is conected the correct way round. ie positive and negative ,
Second check your solder joints. It is possible to have dry joints where all looks ok but no voltage will pass. Try re-melting the solder to remake the contact.
If the above fails try another battery. It that fails it could be part of the electronics which is daed..
let us know how you get on..

Thanks for the video, changed the battery over easily, even with my dodgey soldering skills !! worth emphasising not to over-tighten screw at the bottom as I rounded the edges of the triangle bit on my charger. I had to then use the services of a red hot screwdriver to remove and a bit of silicone sealant afterwards, excellent video though. made me smile all day knowing that I’d saved a few quid . easily pleased me !!
February 28, 2011 at 1:37 pm
Searched for some time in Holland looking for a “how To” web site until I stumbeld upon yours. Excellent! Changed the battery without problems but could not re fit the spring because the battery is slightly longer. Used cut up rubber band (from the mail man) instead, works just as well. Greetings from the Netherlands and thanks. Paul.

HI paul.
Glad It helped you but why was your battery longer ? Did you buy the wrong one ?
nobbly
March 1, 2011 at 8:20 pm
When I checked the battery length it was the same or very close. So I think I messed up while soldering the – pole (miplacement of the soldering lip). As a result the battery position is wrong (too far in the direction of the brush head), leaving too little space for the spring.

Fabulous videos – would never have tackled this without your help. Looked at a couple other vids on this and yours is far superior! I do have a question about the battery. Mine is a bit larger (50MM) than yours and I suspect, like the other person who posted from the US, I have a “full A”. Thing is, when I search for this kind of battery, the searches turn up AA, not A. Is that right? The one I’ve removed only says Sanyo, NI-MH, JCH. No other info.
January 3, 2011 at 8:42 pm
Hi there. I have added more info for those who need more help with battery sizes..
IF your is 50mm it could be A or AA.
“A” has a diameter 17mm where an AA is much thinner with a diameter of 14.2 mm
check the size chart here. http://www.powerstream.com/Size.htm

I have my Triumph for 2 years, since Dec 2008. I remember because it was the month I got my braces and had some fillings done. Then I decided the regular hand brushing is not enough for me. I hate going to the dentist.
I heard you said you replace your battery each year? Mine been fine for 2 years, I havent replace my battery yet.
I read the manual and it says to have the battery last longer, make sure you always fully charge the battery and every 6 months or so unplug the brush. Use it until there is no more power from the battery and then recharge it again.
This will keep the battery going longer…
Maybe this is why mine lasted 2 years.

HI there,
Yes you can let your battery drain down once in a while then fully recharge it and this should slow down the memory effect on the battery.
Also not leaving it on charge also might help your battery last longer but one day it will go lazy and not hold it’s charge very well.
BTW I did say after 1 or 2 years on the VID
thanks for your input..

Nobblynoel,
Thank you for the video on how to do this. As you mentioned my battery was a different size. It’s a full A size.
One problem I ran into was that there is a coil around the top of the brush made of very fine wire. While trying to pull out the spring I broke the wire off of the circuit board. The display on the brush went into a “weird mode” where it was cycling through the segments in a round robin fashion. I figured I really messed it up but after a few minutes the display went back to normal. I figured at this point I didn’t have anything to loose so I continued with the repair.
Everything seems to be working and I am currently charging the brush with the new battery. So far after I’m not sure what that coil at the top of the brush is for but so far breaking it doesn’t seem to have rendered the brush worthless.

The coil at the bottom is for the induction charging off the battery. The coil at the top is an antenna for the signal transmission to the wireless display. It will explain why your toothbrush still works but maybe you smart guide doesn’t or you range is limited.
It can happen that the display will start cycling through the segments . It seems to be a test mode you can get in and out of this mode by pressing the smaller of the two buttons. The one that changes the speed..
hope this helps..and thanks for the input.
I will add info about the flashing segments to the blog.

Thank you for the fast update to my question.
It’s not a big deal to me if the wireless display doesn’t work properly. Just glad it wasn’t something functional.

Hi,
What tool did you make to open the brush? I opened mine to check which battery was required and ended up screwing the cover back too tight, now the plastic triangle on the charger has rounded and I can’t open it… Cheers Mark

hi mark
Before I knew about using the plug I made an adaptor. I used an m8 bolt the head is 13mm>
Draw a triangle on the bolt head it and then grind the head to the triangle lines then round off the three corners of the triangle and grind to fit your toothbrush..
hope that makes sense

It’s not necessary to chop the tags off the battery, the little LCD display pops off and then you can simply unsolder the tags from the circuit board – probably saves a few minutes and the most fiddly part of the job.
November 25, 2010 at 5:04 pm
Hi there
What you say is true. You don’t need to chop the tags but if your like me, even though I have a large array of tools, I didn’t have a very small torx/hex screwdriver adapter , i thought it would be easier just to leave the LCD in place and solder on to the existing tags. you might also need a solder sucker if you want to remove the original tags from the board which I have but others might not,,
All the best

Nobblynoel…thank you so much!!! I was told to just throw the toothbrush (and $100) away. Charging the new battery now…you rule, my friend! It was very kind of you to publish this video.
November 18, 2010 at 8:51 pm
Your welcome. I’m glad that it helped save the planet.
The thing is that most things can be repaired quite cheap if you put your mind to it.
All the best

You, sir, are awesome. Thanks so much for the videos. I’ve been meaning to undertake this project for ages, having successfully changes the batteries in my Braun razor some time ago. However I was worried about the disassembly of the toothbrush. The instructions lead one to believe that once you undo that bottom screw all is lost, but your videos gave me the confidence to press on. A couple of notes:
My model, also a Triumph and one that looks practically identical to yours, took a full A sized, 2500mAh cell. Maybe mine is longer? It’s a Triumph Professional Care 9000, Type 3731,
sold in North America. My local battery shop (Battery World in Calgary, Canada) sold me the cell for $6.75, including GST.
Also, by making a little fold in the new solder tab, I managed to get the old and new solder tabs to interconnect a bit before soldering, so that the connection has a bit more mechanical strength than it would if it were just held by a dollop of solder.
Thanks again for the disassembly and reassembly video.

Hi there,
Well i’m happy that you found my videos useful. As for the battery I have added a note saying check your battery size before you order one.
all the best.

Great guide. Thanks to your video it took me 10 mins, now charging the new battery.
The original battery in mine was the same length as AA, so the 4/5A replacement was a bit on the short side, but the spring takes care of that.
November 13, 2010 at 3:01 pm
Hi there,
yes I forgot to say check first to make sure your battery is a 4/5 as not all models are the same. A “4/5 A” battery is 43mm long x 17mm
I will add this to the top of this page..

This is the best, most relaxed DIY video I’ve ever seen.

Hi Noel,
I’ve just bought a battery from the website mentioned and I’m going to follow your excellent videos to replace it. Can I just double check I got the right battery please? This is the one I bought…
4/5 A NiMH 2000mAh 1.2V cell with solder tags (High Discharge)
Thanks mate, keep up the good work – I wasn’t gonna fork out another £100 for a new toothbrush when there was nothing wrong with it (apart from the cr@p battery of course!)

Hii there,
Thats the right battery if you have the same toothbrush as me the Oral B Triumph.
I think is was £1.99
good look…

Thank you very much for sharing this guide! I’m already charging my new battery. For Hungarian folks: you can order this 4/5 A battery at http://www.conrad.hu/

Well thanks to all who suggested using the power adaptor to unscrew the back. Hey I didn’t know so I thought I was being cleaver making my own adaptor.
Well I have took your advice and remade part of the videos so it now includes the correct procedure for screwing the back. lets just forget I didn’t know
Thanks to all and appreciate your comments..
Lets make the world better and repair everything.

Hey, great video.
I didn’t spot the triangle on the charger either!!
Regards

September 12, 2010 at 9:20 pm
Thanks for the video, however there’s no need to make the tool to get the bottom off, the triangle shape is moulded into the charger, just use that!
September 11, 2010 at 9:11 pm
First of all thank you for this video, it showed me the general view of what a need to do to put my toothbrush to work again.
The only comment is regarding the tool you came up with, it was totally unnecessary since the sort of triangle shape tool needed to open the battery compartment is on one of the sides of the power cable plug… the plastics are really soft so being gentle its a must
Thanks again!!
September 11, 2010 at 6:52 am
You do realise that there is a tool on the charger to undo the screw on the toothbrush?
September 9, 2010 at 11:49 am
Why aren’t you using the charger to open the toothbrush?
September 6, 2010 at 10:04 am
Great video! It was just what I was looking for on the web.
I just want to say that there is an easier way to open up the toothbrush . It is to use the triangler key that is on the side of the charger the goes into the wall.
September 4, 2010 at 2:24 am
Im gonna give this a go. nice video. BTW where did you get the battery, can you post a link thnx!
