Can I use any Ni-MH AAA for my cordless phone?

[volcs0]

Our Panasonic cordless phones are no longer holding their charge (about 2 years old now).

The sticker inside the battery compartment says to replace them with:HHR-55AAABU or HHR-4DPA, both of which are rather expensive ($5/battery). I need 8 all together (2 per handset).

Any reason I can't just get these?
