Braun 7526 Shaver Battery Replacement

[@davidferster2263]

This procedure worked perfectly on my 15+ year old 8975. I upgraded the battery from 1500 mAh to 2300 mAh, cleaned out 15 years worth of gunk, and it runs like new.

Thank you for the upload. Most informative...flux pen, different temperature solder tips, cheap Chinese solder, all stuff I was not fully aware of. Purchased a Braun 7505 recently from a second hand shop, batteries were almost dead. With your video I now understand how to replace the batteries. One can basically learn anything from KZbin videos. I love repairing older equipment as opposed to throwing it out and buying new stuff.

[@gw1973]

This video was EXACTLY what I needed, thank you! You explained the process very well, so I was able to replace the batteries in a short amount of time. I have very little experience using a soldering iron, and I was able to do it successfully, so anyone with a little free time on their hands should be able to do it. It feels great to fix something rather than throwing it out and buying new. Thanks again! :)

[@paulsharp1560]

I followed your directions exactly, even made a solder bridge and had to redo it. Perfect informative video, Thanks!!

[@wjhjr1415]

I love watching skilled, knowledgeable people clean things for soldering and then wiping them with their oily fingers.🤣. Really good info. I'm going to do mine.

[@richards.5354]

Great job putting this instructional video together! I have the same razor and was contemplating changing the batteries in it about 5 years ago and just never got around to it. Well, I finally had some down time and found your video. I had everything in my toolbox except the batteries which I ordered for about $10 from Amazon. It took me about an hour from beginning to end. WOW!!! I have a new razor! Hopefully it will last me another 16 years. Thanks again!!!👍👍👍

[@stadt-mensch6302]

KZbin is, when a german guy has to visit an American site, on how to fix a german shaver. Love it. Thanks.

[@Boffin55]

Bitte.. but you missed the "watch a Canadian Guy" part...

[@rogozzy1]

Great Video. Isn't there a charging issue if the mAh value is above the original Batteries?

[@RickRowen]

That was super helpful, thank you for taking the time to record & post that!

[@davidschwartz5127]

I thing I bought mine in 2005, I've replaced the foil several times but as you discovered its time for a new power source. Thanks for the Video!

[@danmar007]

Didn't expect to find a video for my shaver. That doesn't happen often. :-) Thanks. Very helpful.

[@practicalmedicine4359]

Despite my limited and rusty soldering skills, I got it done successfully. Many thanks

[@mikepedraza1743]

Just replaced the batteries on my at least 15 year old shaver and it works perfectly. I have 3 newer Brauns and honestly this old gal shaves just as close as those newer ones do. Glad I didn't toss this so long ago!

[@99kash]

Thanks! Worked just like the video. I had to trim the leeds down a little as they were too wide for the board. The solder sucker works great! Thanks for the recommendation.

[@Robby4Jesus]

Lost the cord to my newer shaver, found my old Braun in the drawer, i prefer this old unit anyway, thanks for the vid, it'll be getting new batteries this weekend i think

[@JC-hi6yi]

awesome...had this shaver for over 20 years and it was excellent. But the batteries were not holding the charge. I bought replacement batteries with the tabs and I'll be using the video to replace mine. Thanks

[@slavasobko6800]

Велика подяка за ваше відео. В мене схожа модель - Braun SyncroPro 7765 працює з 2005 року без жодного ремонту. А зараз, з допомогою вашого відео зміню старі акумулятори на нові, зміню сіточку і буде ще працювати з десяток років. ))) Дуже чудова бритва, а може ще і тому, що зроблено в Німеччині, а не Китаї. Привіт канадійцям, та їх сусідам українцям!

[@puddking]

Great video, thanks. Unfortunately, in the process of replacing the batteries, I killed the LEDs that indicate 🔋 and charging etc.

[@Nick-md1jk]

Great reference. Be super careful however on the bottom terminals to avoid solder spill. I went over just a smidge and it meant I couldn’t actually turn the shaver off!!! 🤣🤪

[@dimm0k]

thank you for this! charging mine with newly replaced batteries right now thanks to your detailed video on the tools used for this relatively easy task, made even easier with your video!

[@joejordan4812]

Excellent. I've had this shaver for 16 years and the batteries finally died on me earlier this year. This was very helpful!

[@dezafinado]

My 7526 is 16 years old and barely holds a charge. Will there be a problem if I don't replace the batteries and plug it in to shave ?

[@GGSF28]

Great video but would it have been easier to cut or de-solder the old battery contact and re-solder it using the old contact instead? See 6:18 for a clear view of the contact.

[@touche9239]

I think the problem is that the original contacts are tack-welded to the cells.

[@더50]

어떤 사이즈의 드라이버를 사용해야 하나요?

[@sepehradib8041]

Great video, thanks. I've tried to replace the batteries on 7680 which comes with a digital display. After 10 to 20 mins charge it overheats and "temp!" displays on the digital display. I've tried this with 2500mAh, 1900mAh, 1500mAh and 1200mAh batteries, same outcome. I wonder what could be wrong! Any ideas?

[@ИльяФилатов-э8о]

It is necessary to put batteries with a capacity of no more than 800 mah.

[@aushako]

Great tutorial. Not any battery though; NiMh 1800 mah with tabs are preferred (available on Ebay, myself got it there). Higher capacity battery are reported to confuse the on-board computer logic.

[@Kobe29261]

Apart from saving the materials from the landfills the 7526 had a 'random' foil pattern that works excellent for my facial hair; actually have the newer Series 7 with the hexagonal/honeycomb modular pattern and it grabs and pulls. Dug out this old one to find out why it worked so well and I suspect its because the foil is both recessed plus close up inspection of the foils will reveal it has random* perforations

[@fernandosarasua9473]

Great job, thank you very much. I got a Braun series 5 - 8995 that I am trying to get into the head (motor) part of it, but I need a SERVICE MANUAL and so far I have not been able to get one. Got any ideas? Or any body else? Thanks again.

[@KL3NCH]

Good video. I also learned about the value of a flux pen (on my bucket list already) and that Weller have different ratings on tips (although my Weller TC Station has presettable temperatures.) Thanks for this. I'm going for tagged cells though!

[@DavidGetling]

Many thanks I've got a 7790 which I think can be handled the same way. It really is scandalous that for just a dead battery most people have to either replace their shaver. What an incredible waste of this planet's resources. Governments should pass laws that force manufactures of shavers and toothbrushes to make it easy to replace batteries.

[@DavidGetling]

The operation on my 7790 was a success. But there are a couple of points to note. While I was able to buy batteries with tabs I needed to file them down to get them through the circuit board holes. Also as the video points out you do need a good size bit on your soldering iron, and if, like me, your soldering skills are very rusty then you may find it hard to produce nice soldering. What I did worked, but I'm pretty ashamed of my soldering and won't be too surprised if it eventually fails.

[@davidschwartz5127]

[@george78779]

You have a good Weller soldering iron.

[@hirosi700801]

すばらしい動画をありがとうございます。 とてもわかりやすく、役に立ちました。

[@paulwendywiltshire7390]

A big help, thank you!

[@mrobarton7192]

Thank you for the video. I disassembled mine for cleaning because the slide switch was not fully functional. Can't say much for German engineering since the thing was absolutely full of whiskers. It really should be sealed or shielded better given its intended use. Oh no thank you again

[@talmonster]

Thanks for the great tutorial. I have the same razor with the same problem and I will take a shot at replacing the batteries.

[@andreshiguita7575]

Friend can you send me a photo of the loader of this skimmer, I need to see the tip of the loader.

[@giovannivalarani125]

Grazie, ottima spiegazione.

[@dl7851]

exact battery size

[@Haightfilmproductions]

I installed the battery’s and plugged it in for a charge. Charging light does not come on and the shaver gets warm

[@Boffin55]

A couple of things to check, make sure you have the batteries the right way around, if you're looking at the shaver with the connector at the bottom, the left battery is positive on the top, and right battery is negative on the top (obviously different than the bottom). Second, make sure there isn't a short between the connector at the bottom and the bottom of the battery, if there is put a little tape between the two. Lastly, on the top battery, make sure you haven't blobbed the solder, it's easy to short out one of the contacts to another that it shouldn't connect to.

[@Haightfilmproductions]

@@Boffin55 The new rechargeable battery’s are in but they don’t take charge after a full four hour charging. I plug the unit into the outlet and it will work but will not charge the newly installed rechargeable battery’s, interesting 🤔

[@buenafe]

Thanks for creating. I was considering to replace battery, but after watching the video, I'll pass. I don't have all the tools you have.

[@ELEVOPR]

Awesome, thanks for posting this. Great work by the way. I found mine up in the attic I put it away about 8 years ago and forgot about it. Well i charged it up, powered it up, and the motor runs pretty low. when i insert the power cord, it runs like a champ. so i think my batteries are bad. I will need to replace them as well. is it true if you use batteries that are over 1700mA that the firmware on this device would be confused and shut the razor down ? I see you used 2500mA did you have any kind of issues? are you able to reset the frimware some how ?

[@scottbrynen5488]

I used some old 2500s and no issues, and you can get inexpensive 1500ish one from any store these days

[@billyostendorf8044]

Anyone's razor not turn off? Button not letting slide return back to shut razor off?

[@DeutschlandGuy]

@@billyostendorf8044 Hi Billy. I had the same problem today out of the blue. This is the first issue I've had with the unit since I bought it new in 2002! (Today is 8 April, 2020.)... But ya... suddenly it would not shut off. The slider seemed to be stuck and would not slide all the way down to the off position. Luckily I found Boffin's video here on battery replace... So with the raiser humming away at full speed, I managed to use this video to take it apart. Once I got down to where I could remove the batteries, it finally stopped running, of course. I notice the mechanism for the sliding switch is on the opposite side of the unit than the batteries. I can clearly see all the moving parts but I can't figure out what is keeping them from working properly. So I am wondering if you ever got yours to stop running and if you could fix the slider mechanism so it would turn on and off. I wanted to as Boffin about it, even going to his referenced blog site (a Wordpress site) but he doesn't list an email address there. Any assistance (tips) you could give on getting the switch slider to work again would be greatly appreciated. Or... if you happen to have Boffin's email address, I could try there too. I really love this raiser and would love to get it running again. RJ

[@YosemiteJohn]

Why doesn't Braun just make these things so the batteries snap in, like most everything else until some cell phone makers solved their battery problems by sealing the things together with glue. I've worked out most carpentry problems I've had from having one hand paralyzed by using various clamps, vices jacks and power tools, but soldering isn't something I've figured out a workaround for yet so haven't bought any tools for that in about 40 years, and that was just plumbing not circuit boards like several friends of mine in the Navy used to do. But now at least I know what's inside it and what does work so will think on it for a couple years as Io have a spare I bought 15 years ago of a similar but newer model as the charge and clean stand of the 7000 series had a plastic part that kept breaking so have been using the 7526 with the cord most of the time and cleaning and lubing by hand. Mine is 26 years old now give or take a few months and just stopped charging the batteries yesterday, but the current is still running through it with the cord attached so will keep as a spare if have to do some traveling or spent a couple months in a hospital again though I'm getting a bit too cheep to spend time in a hospital anymore. Good DIY video though, if had the tools and use of my left hand would fix that little problem in the morning now!

[@Kobe29261]

Hope you find an apprentice John! If I lived close I'd love to learn under your supervision! We need to bring mentorship back! Sounds like you've seen quite a bit!

[@rogozzy1]

One side has the switch position markings.

[@motleydesign]

Hallo Boffin, my 7570 shaver will will not turn of anymore. I open it and clean it from the inside hoping it will turn of again but it does not. What do you think is the problem? 2 hours later i found the problem :)

[@ivyleague3224]

Hey my 8975 series 5 did the very thing, can u tell me what causes it plz thanks

[@kanechan3734]

Thanks for your video! Good!

[@pic352001]

Really thank you👍🏻👍🏻👍🏻🤘🏻✨🍀
