How can I have battery backup for internet service during a power outage?

I have Fios internet service only, no other service (no phone, no TV).

Optical Network Terminal (ONT): A few years ago, a verizon technician replaced it with a small black device Verizon Nokia 3MV00736AAAA. Here is photo on basement wall.

I would like to replace the black device with something (including backup battery). I just chatted with customer service and he said he placed an order of power tray (yes, he said power tray in chat window) for me, then I can buy battery on my own, I will need to install on my own. But later on I noticed it is Voice Backup PowerReserve in order confirmation email (after chat session).

Goal: All I want is to have uninterrupted internet service during weekday daytime. But sometime thunderstorm can cause a few minutes of power outage, that is why I need battery backup.

What is the difference between UPS and Voice Backup PowerReserve? It seems that UPS can be used to provide battery up for internet service, while voice Backup PowerReserve cannot provide battery backup for internet service. Am I correct?

Edit: Typically, it is neighborhood wide power outage, such as falling tree branch brings down power line and causes power outage of a few hundreds customers, maybe UPS cannot provide battery backup for internet service either.

I believe that you are correct. Years ago, the old white ONTs came with batteries included. But these batteries only powered the landline phone. It never included internet backup. I always hooked up the generator for that. I was unaware that the new ONT even had this option.

How much does it cost to set up generator for small single family home? Does it make a lot of noise (bothering neighbors)?

Costs vary widely and depend on whether you want a portable, a permanent partial house, or a permanent full house. Noise depends on the muffler. My small Honda isn't terrible, but everyone knows I'm running it. It's a power outage, what else you gonna do? Also with your UPS, don't forget you'll need one for the router too.

Thanks. I already have one UPS for router, second UPS for desktop/laptop/multiple monitors.

Now I need third UPS for the black device Verizon Nokia 3MV00736AAAA.

Now my question: if there is neighborhood wide power outage, for example, thunderstorm could cause power outage for a few hundreds of customers. In that case, will UPS keep internet service active for some minutes?
