Re: Braun 5520 Shaver Stopped Working

The "Braun 5520" doesn't have the 2 screws under 2 small caps on bottom, as described by so many on these boards.
The round plastic plug receptacle 'itself' is the release. (Twist-Release the outer ring.)
Look on the base, where you plug the AC cord in.... Just inside the rim, you will see two small 'recesses', opposite each other, that allow a wedge tool (like a large screw driver) to turn the rim counter-clockwise (left) 45 degrees, releasing the base and housing.
Once this is unlocked, slide the cover off and pop the black retainer cover off to reveal the "PC Board W/Batteries" module/assembly. (Batteries are NOT replaceable by themselves.)
There is a tiny (and I mean "tiny"!) resistor that burns out in the circuit board and causes the majority of power malfunctions in these models.
You can order a new PC Board (with batteries) for approx. $40.00. (+ S&H)
One place is: "".
(Fits Models: 5510, 5515, 5520, 6515, 6520, 6510, 6512 - Types: 5505, 5506, 5705, 5706)

Or, find other by Googling "Braun 5520 Circuit board assembly", and/or replace this model with your number.

To get the ring to turn you have to remove the ring assembly from it's socket and remove the two spring loaded lock pins that are behind it then put it back in it's spot just clips in then reassemble the razor then it will turn and lock

Re: Braun 5520 Shaver Stopped Working

Ron_Ray, your suggestion was fantastic. However, I now cannot close the shaver - I can't seem to turn the plastic plug receptacle clockwise to save my life. Is there a secret for getting it to turn? Thanks again!

How do I open my Braun 9585 Pulsesonic shaver to replace the battery??


Remove the electrical cord from the base of the shaver.

Press down and slide off the panel on the front of the shaver.

Remove the two nickel-plated batteries. Use these batteries as a guide to purchase new batteries at a hardware store or home repair store. Recycle the old batteries when finished. (Many hardware and home repair stores have battery-recycling stations.)

Put the new batteries inside the shaver and press gently to pop into place.

Place the front panel back on the shaver and plug the electrical cord into the bottom of the shaver. Connect to an electrical outlet to charge.

I need to replace batts in a Braun #5520...i donr

You will need to remove the two screw covers on the bottom of the shaver. They are on each side of the hole where the cord plugs in. Then remove the two screws to take off the bottom and you can then slide the outer case off the bottom also. You may need to change the position of the lock to get this outer case off.
You will then need to remove the black plastic back of the inner case. It snaps on so you will need to 'unsnap' it. You can then remove the circuit board for easier access to the batteries. Reassemble in reverse.

You can purchase batteries from See link below

be sure to read the installation note on the item page

I own a Braun Electric Shaver Model 6525 Flex Ultra Speed. I plug it in and nothing! I am pretty sure the rechargeable battery needs replacing and I don't know how to open the razor to replace it. Also the...

if the shaver is DEAD and the green light no longer illuminates when you plug it in, the circuit board is almost certainly bad. The circuit board will burn out if you run the shaver from the batteries for a long time after the batteries have stopped charing properly.
you can purchase a new circuit board which has the batteries alrady on it. it just needs to be dropped in place inside the shaver.
you will find this part at see link below

Braun electric shaver will not charge.

Your batteries are no longer capable of being recharged and need to be replaced.

If you are handy and can dissemble and solder, you can do this yourself, otherwise, you can send it off to a repair service that will do this for you.

If you wish to do this yourself, you'll have to take the shaver apart. There are two (2) small plastic caps on the bottom of the shaver that can be removed with a small pick or flatbladed screwdriver. Once those are out, you can unscrew the two screws that hold the shaver together and gently pry off the side panels.

This will expose the internal circuit board and the rechargable batteries that need to be unsolded. You can then reinstall NEW rechargable batteries and solder them onto the PCB (printed circuit board). You can also purchase a complete internal PCB with the batteries and everything you need, you just swap out the electronics for the new one, although this costs about $39, while the batteries alone are much less.

Put the shell together and reinstall the retaining screws and caps and you're done.

Here's a link to get the replacement batteries for your shaver. They also do the repair service, if you don't want to do it yourself.

Hope you find this Very Helpful and best regards!

I have the same problem with my Braun 7570 as the Jan.8, 2008 writer about the 7526 or 7680 shaver. The blue button came off but the shaver still works

This button wears out or just fails with time, but is replaceable.

Braun 7526 Syncro Body Housing with Trimmer
$12.99, Fits Model: 7526, Type: 5493, Includes back case, front case with trimmer/switch, side grips and bottom 'plug',

To disassemble the 7000 Series Braun shaver.

Disassembly of the 7000 Braun shaver is basically the same as the 8000 series Braun shaver listed below. The 7000 is actually easier to disassemble as the plastic is much thicker and the bottom socket cover pops right off as there are less tabs and they are bigger.

To disassemble the 8000 Braun Series shaver.

Remove the plastic cover on the bottom that covers the corded socket. Be careful, there are a total of two tabs on the short sides and four very small tabs on the long sides. I usedmy fingernail to create a space big enough to insert the corner of a credit card in the center of the long side opposite the blue light indicator, then gently removed the cover. Using a screwdriver could damage the plastic.

The two sides then pop off, they only fit on their respective side when replacing. Don't lose the two small black seals on the top of each side piece.

There are a total of four screws holding the body together. Remove the screws, using the proper flat blade or torx screwdriver. The shaver will then split into. You can then remove the the Motor Drive Unit and the separate circuit board with the batteries.

This would also be a good time to clean the goo buildup from around the shaver head.

Assembly is the reverse of above. The Motor Unit will only fit in one way, there is a flat side and a angular side. Be sure the pin for the trimmer is placed in its proper hole, or it won't extend.
