Cordless phones

When we moved here, the kitchen had what is probably second generation cordless phone--lots of heft, ugly as sin. Probably from the early or mid-90s. But we sort of got used to being able to walk around, or keeping it in the living room in the evenings. So I bought a GE 900 cordless phone for my husband's office about 5 years ago. I had to use the laundry room to dock it since you need a phone outlet and an electric outlet side by side, but that wasn't much of a problem. (I have no idea why the previous owner had both a phone jack and cable connection in the laundry room, but maybe she ironed more than I do.) Lately, it's been dying after an hour or two off the docking station, and he's been keeping the kitchen phone in his office (it no longer rings), and that's not handy or conducive to good marital relations. So today I looked up the cost of buying a new battery, Sanik 3SN-AA60-S-J1. Seems it is about the same cost as the phone was ($14-15.00). So he bought a new phone.
