home router battery backup

At my last employer we installed lots of Adtrans at Car Dealerships, Hotels, and other SMBs.    It was common for them to have a small UPS but 9 times out of 10 the UPS 2-3 times older than the life cycle of the battery and no one ever knew that you could change the battery in them.    So they usually just had a heavy power strip that was prone to failing after a power loss.

We did have the option to install a battery back up on the Adtran but it would have been useless because most of them didn’t have any kind of backup power for their PBXs.

I’m pretty sure that my own power protection on my network gear and theater gear far exceeded the average end user’s remote offices.

I know that the FCC has a regulation since 2015 (47 CFR Section 9.20) requiring ISPs to provide an option to voice customers to purchase a battery backup for emergency voice services during power outages. As this is only an option and only applies to customers who subscribe to voice services, I was wondering if anyone had any insights on the prevalence of battery backup for home modem/routers? I.e., what percentage of home users actually install a battery backup in their home modem/router or use an external UPS?

Given that most people barely even know what their home router is, I suspect the percentage would be somewhere south of 1 percent. Outside of my home, I honestly cannot recall EVER seeing someone’s home using a battery backup for their internet infrastructure.

I personally do, but of course I (and probably everyone on this list) am by no means representative of the population at large in this particular area.
