Replacing batteries on Panasonic Dentacare EW1211.
This is where I ordered the spare 1.800.8 Panasonic 1.2v Ni-MH 1100mAh batteries from:
www.espares.co...
I ordered the iFixit 64 bit driver set from Amazon:

And I got the MINI ES121 electric screwdriver from Bangood:
eu.banggood.co...
(The above two affiliate links)
It turns out Panasonic do have instructions for changing the battery on their website but the PDF is in spanish:

Thanks for the disassembly video! Sure was easier than I expected!
A couple of AA batteries does just fine, even better because AA batteries are easier to find in good quality.
The receptacle terminals can be slightly bent to make contact with the battery ends, even without the weird bars.
Bent and put some plastic from old bank card between case and terminal. And better to use double sided tape to be sure, that batteries are still in place.
Thank you Alex; I had exactly the issue with dead batteries, ordered the replacements, followed your guide and we are as good as new again!
Thank you for the very clear guide. Got 1/2 way there and still had to explore the little Torx screw in the top end.
Thank you very much for showing how it's done. 🎉
You don't need to remove the torx screw to replace the batteries.
Also, I have a manual for the original EW1211 in 18 languages including English. I don't mind uploading it somewhere if somebody needs it.
Could you please paste the link here?

If you go to the Panasonic website for the region of the world where you live you should be able to find a manual in your language.
13€ la pile, ça fait 26€ les deux et 30+€ avec livraison, alors que le produit neuf coûte 36€ 😅
Thank you very much. I replaced the batteries in ca. 30 Minutes. When reinstalling, you have to press the start button, otherwise it will stucks.
Very kool! Thanks for your pulling it a part, putting it together and making such a great video!! I have an EW1200 and it is non functioning although the base has power.
And does it work again after replacing the batteries?
Very many thanks for this useful vid. My EW1211 seals had failed and caused water damage to the PCB. (They need conformal coating really.)
Thanks Alex, could not have done this without your video, very fiddly to do. Try to avoid the batteries going flat by using it regularly.
Merci pour ce tuto, j'ai le modèle EW1311 qui est quasiment le même pour le démontage. Mais le mien était plein d'humidité et de moisissures à l'intérieur, j'ai acheté un modèle sans marque connue. Je verrai bien à l'usage, le Panasonic avait duré 3 ans et demi quand même. Là où d'autres de marque non connue avaient lâché avant la fin de garantie les années précédentes...
Merci ton tuto est parfait
Ce qui est débile c'est que les vendeurs de batterie ( amazon pour moi ) pour le EW1211W vendent les accus 1 par 1 , et bien sûr n'en ai acheté qu'un seul ( 11€ ) , là je dois en recommander un autres ( 11 € ) , ça fait 22€ d'accus pour la réparation....
No need to remove so much screews, just 2 at bottom and 1 on top. Water tank can stay.
Thank you, very good tutorial; I've just changed the batteries now :)
Thanks a lot...... The gadget is perhaps designed in a way that the batteries can't be replaced...... It was a major hassle right from opening it, sourcing the batteries and assembling back. It wouldn't have been possible to do but for your guide
Judging by the cleanliness of this machine Alex is working on a new one. I found the batteries didnt come out anywhere near as easily as that, some corrosion had set in around the terminals and 'welded' them in. And no you do not need to remove the torx screw.
I did take the opportunity to clean the parts while doing this. I found there was white limescale residue on some surfaces, mostly obvious on the blue tank.
The splits between parts had collected some gunk. The sealed areas were clean however, I think you can just about see a tiny bit of corrosion on one terminal at 2:44, so maybe humidity was still able to get in. NiMH are meant to be quite good at not leaking electrolyte unless overcharged/overheated but apparently it does still occasionally happen.
I think I worked out the Dentacare was 4 or 5 years old when I did the battery change.
Were you still able to replace the cells and get it working?
And yes, the torx screw can indeed stay in if you're just changing the batteries. I think I was just having a bit too much fun with the driver set!
Thank you very much for uploading!!!
Why can't they put easily removable batteries?What stupidity and harassment fir users.
Thank you, I just repaired two of them.
Thank you Alex 😘
Nice thankyou for the vid. Was able too open it now in the proper way. Mine is a litle bit differant from inside. I see i only got to order the replacement battery's somewhere hehe. Were did you get the battary's?
I ordered my batteries from espares.co.uk but Pat MTL has commented below that the french site adepem.com also has them for a similar price.
Thank you so much, Although once you got to pulling the battery and motor internals out, it looked just like a sex toy, as I have done this for a friend who watched me pull it apart and then said "if I had of know it was this complicated I would have just bought a new one" I then Glared at them very Sternly.
Klipp und klar. Machas gracias!
I bought my battery from Espares and after replacing the old one the water jet worked well for a while but it didnt last long. Now I get two uses before the battery goes flat. Either its a counterfeit or its a manufacturing fault.
I love this modular easy to repair design, but the machines gets wet easily inside followed by corrosion. Also mold is problem.
Bonjour j'ai le même hydropulseur mais il ne fonctionne plus. Le voyant ne s'allume plus comment faire ?
Merci
Vc pode fazer um video desse com o modelo Water flosser WP 450B/462/B.
Se puder agradece.
Thank you very much
Thanks !
thank you
What is the battery size? I want to check if an battery type AA may fit.
Yes, AA batteries can be made to fit. Those weird 1.800.8 batteries are just AAs with extra bar ends. If you're willing to slightly bend the receptacle terminals it'll make contact with AAs just as well. However, keep in mind the bar ends were providing extra rigidity which you'll have to compensate, by example by re-using those foam stickers.
Thanks
Are all the steps the same for Panasonic EW1411?
Yes
Thank you!
I have a similar model, only that it's the "w" variant, and it held it's power consistently throughout the 2 year lifespan, but now it suddenly loses power, can be this be due to bad batteries?
If it does still charge when placed on the charger but just looses power quickly with use I'd guess it probably is the batteries degrading. If it has suddenly stopped working and doesn't run even after charging I'd be concerned something else has gone wrong. If you have a multimeter you could maybe check the battery voltage before and after charging.
mine one cannot broken, device not suck the water, where I can check and fix it.
You may have to suck the water through the nozzle with your mouth whilst switched on in order to prime it. Had similar problem and that fixed it for me.
Bonne vidéo, au bout de combien d'années les avez vous remplacées ?
Je ne me rappelle plus vraiment, mais je dirais environ 4-5 ans, peut-être?
Merci de votre réactivité et pour le lien des batterie, c effectivement le site le moins cher, même sur Aliexpress je n'en ai pas trouvé
Do you really need to remove the little scree close to the straw? I am missing that head.
The answer is no... You don't. Anyway, thanks for the video!
You're right, there area only really 3 screws that need removing. It can however be helpful to remove the straw when re-assembling to make sure it is properly inserted into the rubber tube section (the one wrapped in a spring) and avoid any leakage on the inside of the device.
Lohnt bei den Akkupreisen nicht.
Bravo pour ce super tuto très utile et très bien fait. J'ai aussi trouvé les piles en France à peu près au même prix sur www.adepem.com/dpm182547/batterie-1100mah#compatibility.
Alig bonyolult az elemcsere. Szerszámkészlet mellékelve? Hihi.
Szemem elé ne kerüljön! Ezt kár volt megmutatni, csak elriasztja a posszibilis vevőket!
