Thanks for this video! also regular rechargeable AA batteries will fit with a slight modification of the battery connectors (just fold the (-) connectors on the board‘s side to have a firm connection to the battery) - I used 2x IKEA LADDA batteries. All in all i think this shaver is pretty good to repair, just give it a try :)

Thank you!! Excellent to the point instructions without any distracting sound, it took me roughly 20 minutes to install new battery and reassemble everything.

Thank you. This helped very much. Your video gave me the confidence to take my shaver apart, replace the batteries, fix my trimmer, and put it all back. Works great. I think you saved me $50 - $100. See is believing!

Just did it. Great tutorial. Just had to deal with a lots of oxidation on the board and rotor. Now my 6 years old Braun works as out of the box. Thanks a lot.

Just exchanged the worn-out batteries of my shaver with 3 $ for 2 new with 2500 mAh AA cells. Thanks a lot for your for your tutorial from across the big pond from Germany.

Thank you for this! I was having a heck of a time trying to figure out how to get it apart.

Many thanx, great tutorial - changed the batteries without problems. To other users: Be carefully in the first step to unfasten the small plastic parts under the shear foil - they can easily be lost during disassembling.

Superb video..just changed my batteries on my Braun 3040s, the only difference is I used standard AA Duracell ultra recharge NiMH 1.2 volt 2500mah batteries and had to slightly bend the copper contacts inwards on the shaver battery compartment so a good connection was made and it works just fine ...like a new shaver!👍

Co prawda zajęło mi to 60 min. ,ale bez Ciebie nie poradziłbym sobie. Dziękuję bardzo za wskazówki. Pozdrawiam. (Poland)

Perfect! While I was changing the batteries after roughly 10 years I used the chance and threw all disassembled parts in a ultrasonic cleaner. My Braun 360 looks like out of the box now :-)

Vielen vielen Dank !!! Ohne dieses Video hätte ich es sicher nicht geschafft!

Thank you so much! Would not have been able to disassemble the shaver without your video.

What can I say? Excellent video- very clear, concise and well filmed (apart from when you obscured the tiny plastic pieces on top with your hands-couldnt tell which piece you had put back on.... :-) ) . Very grateful for this. You just saved me about 50 quid. Mines a 3040s wet and dry and as you say it is identical. Many thanks.

Thanks for your video! It was very useful, also for my own model number 340-s 4. Pretty much the same. Tip: I kept the engine white cover, there was no need to remove it.

Thank you! I was looking for a good tutorial and yours is really great! Straight forward and a lot of hints and attention points...

Thank you for this video! It helped me a lot just today evening, while I was replacing the old batteries to new ones. Many thanks!

Obviously, Braun could have put a simple lid on the other side, so that consumers could change the batteries with ease. But no, they wouldn't buy new models as often then. Thanks, I'll try this as a last resort.

Fantastic. Your descriptive text and video made the job so easy to change the batteries. Razor works like new again. Cheers, Hilton Ward.

Thank you, your video made it a lot easier to fit my new battery’s, my razor is like new again. Cheers 👍🇬🇧

I couldn't repair mine, but still thankfull for your guidance and effort :)

I bought a refurbished 3040s but i think the battery has passed it best days, thanks for putting up such guides, so i got the choice now 2 exact batteries which cost about 14-20€ depending on brand and stats, o i try to modify the minus connector as comments wrote and use the best 2 AA rechargeable batteries (imho panasonic eneloop pro 2500mAh) for about 10€, so the winner is i will try it with 2 AA

Absolutely brilliant. I Changed the batteries on my 360. Thanks!

Thanks a million ! I was able to replace dead batteries with new normal rechargeable AA batteries thanks to this video. You see, normal AA NH batteries can be replaced with the connecting metal slightly bended inwards. In Korea, those weird-looking batteries are very expensive due to overseas delivery. Thanks again !

Big appreciation from Taiwan, now I can save my Braun. Thank you

Perfect. My 12 years old 340s-4 is now clean and works again like new. Next 12 years may come :)

Great, step-by-step demo. Thanks very much.

21 septembre 2022, j’ai suivi le guide et tout fonctionne à merveille… merci. I followed your guide and everything works wonderfully! Thank you.

This is a very helpful video. Don't think I would have been able to figure out how to disassemble my razor without seeing someone else do it. New Ikea LADDA batteries installed by bending the battery contacts inward so that they make firm contact with the ends of the cells.

Just finished. It was a lot of mud inside, but now it works as new (18 years old). Thank you very much, for the comments too. I took 2 regular 1,2 V 1400 mAh rechargable batteries.

Tutorial perfetto, non si può sbagliare. Grazie

Fix & Fika, thank you for a great instruction. Although I broke the rubber/plastic cover while trying to pull/peal it off. By the way, did anyone noticed that Cleaning station stops working when battery quality drops? So, no matter how well you charge your slightly depleted/old battery, cleaning station won't work anymore. I throw away my previous cleaning station thinking it was not functioning, just to discover the very same problem with a new one. The shaver was still working correctly and chargeable, just the cleaning station electric motor was not functioning. Then, I replaced the battery on the shaver and cleaning station start working again. Strange, because cleaning station electric motor is powered by approximately 13V input and it's functioning should not be related to battery's condition.

Thanks. The magnets with holes really make your screwdriver have a stronger hold on screws if they are not aluminum or stainless steel.

L'ho smontato, ho ordinato le batterie, tra una settimana le monterò. Ti ringrazio del video, mi è stato utile e se non ricorderò qualche passaggio, lo rivedrò. Grazie

I just disassembled mine, because it indicated bad batteries... As I took the batteries out and measured them (using a Voltmeter), their Cell-Voltage was absolutely fine - so I put the old batteries back in and measured Voltage again, but with the shaver turned on to measure the Voltage with load and it's still absolute fine! Fortunately, I didn't order batteries yet, as my shaver now continues working happily with the old batteries :-)

Great tutorial. Super on point.

Excellent video, thank you so much !

Thank you, Great tutorial

You saved us a lot of money. Thank you!

Very useful video. Thank you.

Thank you so much for the effort!

Thanks, perfect for my 320s-4

Excellent how to video, thank you

Hey dude, nice tutorial, but I’m wondering if you can tell me if there is a way to disassemble the side shaver on the razor. mine has a few small clumps of hair stuck inside near the top on the inside and I can’t get them out!

Are these AA sized batteries? Wonder if I can install some eneloop high capacity NI-MH batteries instead.

Little TIP: Instead expensive FDK batteries (sometimes hardly to buy) a usual AA regeargeable cells (without metal endings like FDK have) may be used. To ensure connection with coppper contacts, all 4 have to be spring up. The good choice may be well known and good working cells like Panasonic/Sanyo eneloop, or GP Recyko+. Do not suggest Varta due to self discharging parameter (even if producer say somenthing else) - my private experiencie with home appliacies and digital cameras. If a RED light blinking quickly after batteries replacement and Braun is not working, simply connect charger and charge the new batteries. It may happen even if new batteries were charged (externally) before.

Thx bro just fixed mine asap

Great instructions!

Dude your amazing thanks

Merci beaucoup pour votre tutoriel clair et précis ! Il m'a permis de remplacer les batteries de mon rasoir à moindre frais. Thank you very much for your clear and precise tutorial! It allowed me to replace the batteries in my shaver inexpensively.

My braun shaver series 3 won't charging.. help me for this..??

very helpful, thanks!!!

wait what? these are simply 2 AA batteries? Thank you so much, this will save me a lot of money

Thanks for the tutorial, fixed my bf razor instead of gifting him a new one xD

Très bonne vidéo ! Pour le 340s-4, il faut retirer le haut métallique bleu pour retrouver le même processus. Attention, les deux petites rondelles en caoutchouc peuvent rester collées à l'intérieur de cette pièce. Very good video! For the 340s-4, you have to remove the blue metallic top to find the same process. Be careful, the two small rubber washers can remain stuck inside this part.

super Anleitung, funktioniert einwandfrei

Perfekt, thank you!

Muchas gracias !!

Thanks! Work for me

Thank you! In the first part of the video you said that we have to pulling out the top part and then the spring.. what is the name of that part?

Great tutorial, I just dit it, Many thanks

i managed to open the shaver with your instructions but unfortunately the small "motherboard" was burned 😞

Nice DIY tutorial. I almost failed. After installing the new batteries there were red and yellow blinks on the board and the charger did not want to charge nor the shaver operate. Somehow it turned back on, but after during the assembly one screw just broke into the device. Now it’s working however the top does not fit properly. Bad luck.

I did the whole procedure and managed to change batteries. That’s fine. But the problem still remains. The reason why I did this was a to get rid off a start/stop problem. It takes 10-15 minutes to start and about 5 minutes to stop nowadays. This behaviour started almost exactly after the guarantee ended. That will say after two years and one week. So it wasn’t about batteries. There was a circuit board inside when I opened it. Have engineers at Braun put a automated product death in it? Thanks for the great video. It had all needed.

Appears that the top does not need to come off. Only the side grommet and the front panel. Can you confirm?

Bravo pour cette vidéo . Mon rasoir est comme neuf ............merci

Thank you very much.

Thank you :)

Great video thanks!! It’s clear Braun does not want the people to replace two stupid batteries 🔋..they prefer to sell you a new one they don’t have a good environmental approach this should be forbidden to reduce waste ♻️

hi, what battery did you use 18650?

The amber light is on for my 320 s-4 (to replace the foil and cutter cassettes), but the foil and cutter cassette seems ok and won't hurt when I shave, how do I know when to replace it? is it when it's hurting me or you can see visible damage in the foil and cutter cassette? also is that 7 dollar ebay foil and cutter cassette from china any good.

Is it necessary to remove the cutting head (other than the foil) to replace the batteries?

Hi, guys, are the steps before 02:25 necessary? It seems to me that the replacement can start directly from there.

Hello I replaced the batteries but the red light keep on blinking and it looks like the batteries do not charge. Any idea? btw thank you for this clip.

Has anyone had this model just not turn on anymore? I plugged in hoping it was not charged but did not help

much to complicated...start at 2:20, use a simple short blade ( swiss army knife in my case ), takes one minute to open the case, remove two scews, that's it.

First I'd like to thank the poster. My Braun S3 3040s appears to be successfully charging in its cradle. Now here are a few tips: 1. You can start at 2:30, without removing the top. I used a small thin pointed, but not too sharp knife. Pushing it upwards very near the top, at the back allowed me to start prizing the strip off, without much difficulty. 2. Removing the bit as shown at 3:58 didn't work for me, but once it did flex far enough to allow me to slip out the printed circuit board with the batteries. 3. As mentioned you don't have to buy batteries with nipples. I just carefully folded a piece of aluminium foil and place it at the negative end to give a tight fit. 4. On putting back the rubber strip pay careful attention to the tabs, so that they are not on the outside. Also don't try to simply push it in right at top. You need to flex the top in before pushing home otherwise it will never go back.

Great Video, can you tell me what model Series 3 was that shaver? 3040? 3010?

Plz, can you tell me the type of the battery? Is it ion lithium?

Why did you disassemble (and risk breaking) the oscillating bridges? This part lifts out as one piece!

Whats the specification of the rechargeable batteries? Thanks

Excellent video! However, I’m asking Santa 🎅🏻 for a new one 👍🏻

AA size battery?

Of course, you have to weigh the cost of a new shaver vs the cost/trouble replacing the battery. If your batteries are shot you probably also need a new foil head, which in my case was half the price of a new Series 3. I bought mine Jan 2014, so it's over 7 years old. I got my money's worth out of it and it still works, but I have to charge it about every other day, and it's probably due for a new foil head.

Thanks for that........I will now garbage my razor.

We don't recommend stripping the agitators out of the head. ONLY remove 2 head side screws. Then pull the rubber grip left and right. Drop the grip down from the center unit. Next remove the 6 screws > 2 top, 2 center, 2 bottom < Replace batts opposite polarity. 6 Screws replaced. Slip grip under the unit, press back together. Remove the trimmer. Redo head 2 screws. Confirm the head portion protrudes out the back of shave. Press the sleeve around. Replace trimmer by placing the dog-legged end of spring in shaver hole the other end into trimmer. Slide trimmer up until it snaps in place. Replace the screen on the head. Charge shaver. Test shaver/trimmer operate. Less work.

Otro motivo para no comprar una Philips, con sus baterías raras y soldadas a la placa.

Не верьте. Сделал, оказалось фуфло.😏 Заряд держит менее 10 минут. Возможна только переделка на внешний понижающий блок. Плату при этом- выкинуть.

Ok fuck it, I'll just buy a new one...

any sound?! rubish :(
