I don't suppose anyone has one of those Aldi rechargeable foil shavers
and has taken the plunge and replaced the batteries inside it?

(FYI for non-UK readers - this is a cheap UK supermarket own brand!)

Mine is about 2 years old, and works fine except that the built-in
batteries are pretty-well gone; it now just holds charge for about a day
or two's shaving, but soon it will be only possible to use it tethered
by its mains cable/charger.

I've opened it up and the batteries (AA or AAA size) are concealed by a
plastic housing and circuit board to which they are soldered. Any
further surgery now on my part will involve breaking into the housing,
which I think will carry a high risk of killing the shaver altogether,
which would be a pity! I can't see any easy way in.

So I'm just wondering whether anyone else has been down this road before
me and successfully opened up one of these to replace the batteries?

Thanks
David
