I must've gotten FiOS 5 or 6 years ago. The installation includes a battery back-up unit for the phone, with a rechargeable battery inside, in case of a blackout or power outage, I guess.
I never use my home phone any more. The other day, the back up unit started sending a signal, indicating that it's time to replace the rechargeable battery in the back-up unit. Of course, Verizon charges like $40 for it.
I don't need this back-up, and I'd like to just disconnect the whole damn thing.
Everything else should work just fine, right?
