Strange battery question!!

[jim76]

Hi
I have a strange non-RC related battery question, but i think some of the cell experts on here will be best placed to help!

I have some cordless phones in the house that have 700mah Ni-cad AA cells in them. They are a few years old now and don't hold a lot of charge, the phone cuts out after 10 mins etc.

Unfortunately Ni-cads are no longer around, so i just wondered if i can put in some normal Ni-MH AA cells like a transmitter. I know RC chargers have different settings for Ni-cad and NiMH so wondered if it would work or not?

Any advice greatly received!! (they other half is moaning as her chat time is limited!!)
