I have a cordless house phone, whose internal batteries are worn out.
They are feeble 700mAh NiCads who hold their charge for only a few
minutes' use now. Can I replace them with some 2100mAh Ni-MH's, of
which I have loads

If they fit, sure.

Hi Homer...

Oops, I'd like to respectfully throw in a caveat here, if I may?

If the phones charging contacts are at all exposed, then make durn
sure that there's a rectifier *inside* the phone to limit current.
Or, failing that, perhaps a very small resistor in series with the
charging contacts.

Otherwise something external shorting them could produce horrible
results. I'm thinking of putting the phone in a pocket with keys
or loose change; or the youngsters tampering with it.

I'd also add that if the op goes this route that he seal the battery
cover up somehow so that the kids can't "borrow" the batteries for
their toys.

I admit to being a little prejudiced; I still have a five year old
scar on my leg from one 1800 mah cell shorting in my pant pocket.

Take care.

Ken
