Braun Rechargeable Shaver Repair

Description

I like the old Braun, made in Germany, single head shavers better than the new multiple cutting head shavers so I have about 5 of the older ones. Unfortunately some of them have rechargeable batteries in them. From my experience, a rechargeable shaver is always weaker than a plug-in shaver and the batteries often fail and slow down before a shave is finished.

Also the batteries inevitably leak, and destroy the shaver with leaking acid. It drives me crazy that I can’t buy just a regular Braun non-chargeable shaver anymore. In my entire life, I’ve never needed to shave from a battery shaver out of necessity…as if anyone actually has to shave while driving to work in their car.

Ok, the rant is over so here are the steps to convert a Braun 5569 rechargeable shaver, to a normal plug-in shaver:

1.Remove 2 screws on bottom and everything slides apart nicely as shown.

2. Push trimmer towards the top so it’s out of the way. Next remove the circuit board and batteries and turf them where they belong…in the garbage. All you have left now is the empty shaver case with the electric motor.

3. Next connect the 2 remaining wires from the motor- directly to the power cord as shown and fasten securely with tie wraps as you don’t want any strain on the small motor wires. Cut off the 110 plug at the other end of the cord as the motor only needs about 5 volts DC. The wires are red and black so it probably wants positive and negative respectively.

4. Before assembly do a test… connect the motor to about 4 or 5 volts DC. The motor has a red and black wire so you can match polarity if you want but it probably doesn’t matter as it worked fine either way from my testing. The motor doesn’t have any voltage ratings on it but is probably rated at around 4 volts DC, but will probably work fine up to around 6 or 7 volts.

5. In the last picture you can see I’ve connected it to a small power supply that measures about 5 volts and drops to about 3 volts under load while shaving. A larger 2 or 3 amp PS would not have this voltage drop under load issue. I measured the current draw, and the shaver draws about .5 amps at idle and this goes up to about 1.2 amps while your actually shaving so you should have at least a 1.5 amp PS for best results.

6. Another thing I find useful on shavers is add an inline switch as you can see in the photo. This saves wear and tear on the small shaver switch and is much faster than plugging the shaver in and out with every use.

7. That’s it, now you never have to worry about your shaver leaking nasty stuff out the bottom or wondering if it will work after not using it for 2 years.
