My battery lasted 5 years and then it died. The beep kill switch only worked for a few minutes and then the damn thing would not shut up.
I don't have a phone line either so I bit the bullet and found a replacement battery on Amazon for 19.99.
Installed it and hopefully another 5 years of silence.
How many times did you hit the kill button? That's why I said one press is like hitting snooze. I forget if you have to hit it more than once, or hit and hold it to get it to shut off permanently, but if you do that it will shut off permanently.
