Hi,

I've got an older Norelco electric shaver, which has some kind of
'fast charge' ni-cads in it (haven't looked, but that's pretty much
what they had when it was made). Normally, it will recharge in about
20 minutes or so. Well, after all these years, one or both batteries
is dying, and I need to replace them. I was thinking of just putting
in a couple of Ni-MH cells (these are 'AA' size), because I know that
they can handle a higher charge rate than standard ni-cads. I've got
some extras of both, but no 'high charge rate' ni-cads (although, I'm
pretty sure I could get some at Tower Hobbies, or similar R/C model
shop).

Anyone ever replace batteries in a Norelco (or other brand) shaver?
Anything I should be aware of or watch out for? Seems like it should
be a pretty straight forward procedure.

TIA

Hi...

I'm in Canada, where Norelco is called Phillips, and I have
one (though there are so many models)

The heads-up I'd offer is to measure the cells carefully
before you get it too far apart at an inconvenient time...
mine has one of the sub-C variations, which is physically
just a little shorter than a AA. Shorter enough that you
can't get it in and still put it back together :)

Take care.

Ken

NiMH cells have a more complicated charge requirement than NiCd.
Unless you plan on designing a new charger,you should only replace with
NiCd cells similar to what you removed.

I replaced the NiCads with new NicCads. No problems after about a year.
Don't remember for sure what size they were but I think they were sub-C.

Jim, could you be more specific? Not to hijack anyone's thread,
but we recently replaced a 3.6V NiCd cordless phone battery
pack (600mAh) with 1300mAh NiMH's, and plan to use the
phone's base (150mV input) to recharge it. If we're careful to
time the recharges properly, what other complications could
there be?
