After searching older posts I was unable to find specifically what I was looking for...
Have a few questions about the BBU [battery Back-up] unit:
- If the power is on and the battery is disconnected, should the internet and TV still work? Or does it have to sense the battery?
- Should the BBU trickle charge [maintain] the battery when the power is on?
I'm not sure exactly how the system works, but I would think the power supply should keep the ONT unit alive/on when the power is on[?]. I don't have telephone service, so I'm wondering why I need a battery..?
Yes, the battery is optional. The battery is ONLY for backup for your home phone service. You can disconnect the battery and still have service on TV , Internet and phone as long as the ONT is receving power from the BBU. If you want to replace the battery. You can go to any HOME DEPOT and get a 12 volt SLA battery.
My question is why do we need to pay for the battery? Why doesn't Verizon send us a replacement when the battery fails since the back-up battery is required to conform with FCC regulations that the FiOS service work even during a power outage.
