Excellent video tutorial. I used batteries with tabs. The tabs were too wide but I just cut them smaller with scissors to fit the slot. The blue lens at the bottom indicating charging fell off on 1 of the 3 shavers I was working on and it won't stay in place now. It's not a big deal. I'll at some point glue that into place.
Should mention a soldering iron is needed! I was on holiday when mine packed and the funny thing is I always forget the soldering iron! Tried it when I got home and yes working so thanks,
I have a Braun 7680, very similar to the one in your video. I got everything apart with no issues, but it appears that the battery board has some sort of clear coat that was "painted" over the top of the solder connections (and most everything else on the board) after it was assembled. Any idea whether it's possible to remove the coating without damaging anything?
Hi Matt, Its possible that the board has what is known as a "conformal coating". In this case the conformal coating will be to protect the pcb from moisture which is good as most shavers spend some time in bathrooms! It doesnt make things water proof but water/moisture resistant. To desolder I'd just scrape the clear coat off the battery cell terminals then resolder.
@@PowerOn- Just wanted to say thanks! I got the new batteries installed and I'm amazed at the results. I didn't realize how much the worn out batteries were affecting its performance. My shaver is close to 20 years old, but now it feels like new!
Thanks! You saved my shaver! Opened it up (upside down) per another UA-cam and a part came flying out; couldn't find out how to put it back in. Your video helped me find the proper replacement. But, my big problem is that the power will not turn off with the switch. Any idea as to what might be wrong?
@@billbahr Hi Bill, I can't really help much but I do have a dim recolection of the issue you describe. I remember the slide switch mechanism incorporates a spring. Maybe this spring is not in the correct way? Anyway open it up again and see what you can find!
@@PowerOn- Thanks. Yes, you are correct. There is a spring involved with the switch. Unfortunately, the switch connector piece was the mechanism that came flying out. Tried but could not repair the tiny piece of plastic that linked the connectors to the spring. Put it back in, but despite several tries, now could not get the razor to turn on. Also in trying I even partially broke the razor-to-cord connection, which could not withstand that many openings, but no major harm done. After some analysis of what it would take to get the razor going again, saw the two metal plates that the switch would connect and soldered them together. Voila, everything worked, albeit the razor is again always on when plugged in! And the chief benefit after all this effort? The razor somehow (the inside cleaning?) works better than it has in years! Thanks again for your great video! :)
Unnecessary for those who know best but then the tutorial wouldn't have the same purposes which is to show those who have limited knowledge or the abilities that you seem to have to do this battery replacement.
Almost tossed my 7570 Braun, which Ive had for 20 years plus; then came across your very helpful video-Thanks!!
@@ageqoudagis7541 Good to hear another shaver saved from e-waste!

Thank you, very interesting, now i can repair my braun !! thank you , well done !!
I’ve still got this baby and running well after 25 years
@@CaffeineJogger Me too, I don't think I'm running as we as I did 25yrs ago 😅😅😅

Good work Frank - a soldering iron is definitively a 'must have' tool for this and many other of my projects!
Hi Simon, Do you have instructions on re-assembling the front blade/power button? Cheers
No, sorry but from memory there are not many parts involved and a spring and detents provide the snap action between the 3 settings
19:07 hi Simom, any ideas where to get a new charging cable,thanks

Can you please make a video how to change or repair the trimmer ?
Burned myself and made globular soldering job but it worked....
How much would this cost to do? I would rather have someone do it for me. Is that possible?
Thanks for sharing :o)
The replacements cells with tabs already welded are about 10usd ea. Then you just need a friend with a soldering iron!
@@PowerOn- Where Can i buy the cells at? Do you have a link?
Great!!!
painful, un nescessary details
