    Hello

    I have a mdium-old rechargeable Braun shaver which stopped working. The
    oddity is that it charges fine and also it runs fine if I take the foil
    off. If I put
    the foil back on, it's inert. I looked over the foil/screen and there
    is no damage
    apparent. Any idea? Thanks.

    Is this a model where the foil assembly also has a trimmer? If so, the
    trimmer could be seized, or perhaps its linkage isn't engaging properly and
    jamming the motor.

    If not, it could be a weak motor. How easy is it to stop the motor by
    applying resistance to the blades?

    Hi...

    Another possibility? Possible since it's "medium old", the batteries
    have reached that point where they can deliver susfficient current to
    spin the motor unloaded, but not enough under load...

    Quick and dirty test for that would be (again) to carefully touch
    some moving part with the foil off; see how easy it is to stall it.

    Certainly possible, and the most likely answer, but I assumed the fault was
    evident on both batteries and mains.
    That could also indicate a weak motor or seized components. If it's like my
    old Braun shaver it has a built in SMPS and intelligent charging circuit,
    there could also be a fault there.

  5. Always suspect the batteries first!

    You may have a point. :)

    The shaver is a model 5471, with the popup "long hair trimmer". I
    checked
    all the linkages and cleaned everything possible, and the shaver (and
    the
    popup thing) only would work with the foil taken off. Same situation
    with
    the thing pluged in, so I thought the battery was fine, but I let it
    charge
    overnight, it acted the same, but by the second day of lying unused,
    the
    battery was dead. Survey says ... battery problem.

    At this point I assume the answer is just to write the thing off and
    get a
    get shaver. Thanks for the help.

    If you have some spare rechargeable batteries you could try soldering one in
    to see if this was the cause. If it doesn't work, all you lose is your
    time, but it would be nice to know what the cause was.

    Speaking of this...

    I have a Braun Syncro 7505 model that is 3 yrs old. I use it 4-5 days each
    week. I have no idea whether this unit has easily replaceable batteries, or,
    like so many other things, the idea is for you to discard it and get a new
    one when the batteries fail.

    How long should they last, and, how easy is it to replace them when they
    die? The cutter / foil replacement is so damn expensive on this thing that
    it should be kept viable just for the investment made in THAT.

    Thanks,

    Batteries for rechargable shavers can usually be replaced.(I've done
    it for the various Norelco's I've had over the years.)
    You'll have to open the unit up to see exactly what type and size
    batteries are in your Braun.(Sometimes you'll get lucky and they'll be
    standard size batteries such as "AA" or "AAA's )

    Here's alink or two:

    Here's a direct link for shaver batteries:

    It's always cheaper to keep it going, especially at the price they
    stick you for on shavers these days.

  12. This link which is not working now and perhaps deactivated for
    good had the service manual. The type-model cross reference guide
    says the 7505 Syncro is the model 5494

    Do a search in the group on Braun for some dissasembly tips, they
    can tricky and so "selfdestruct". Good luck..

    I've heard that some of the Braun batteries are not replaceable because
    they are complete with the board that they are attached to. I know of
    a service center that might be able to help you out. I've used them
    several times to get repairs done on my husbands shavers. They are
    honest and very helpful. You might try them. Their link is
    www.shavtronics.com. I know what you mean by expensive. But I guess
    if you add up all the blades they add up too.
    Hope this helps

    Thus spake :
    If you're a good solderer, you can replace the battery. I've replaced the one
    in my Braun once and the shaver is still going after 5 years.

    You have to be careful when soldering batteries without tabs (best to buy a
    battery with tabs), but it can be done. Google for details, or post here that
    you intend to replace the battery and I'll describe it.

    Good luck

    Please, no "Go Google this" replies. I wouldn't
    ask a question here if I hadn't done that already.
