DC UPS for router? (retrofed.com)

Hi y'all looking for advice here

I selfhost a nextcloud server and a NAS for backups, and one of my challenges has been data corruption after power failures.

I went and bought some consumer UPS units about 5 years ago, which helped, but now the batteries are starting to fail, and I'm not protected from power outages until I replace them.

I have the router on UPS as well so the computers can communicate with each other that the power has failed and it is time to gracefully shut down (using NUT).

However the router itself uses quite a bit of power and I am hoping to make a smarter decision this time around when getting a UPS.

The router's power supply is 12V5A with a barrel style jack, so i have been searching for "DC UPS 12V 5A" to try and find something compatible that wastes less energy converting from battery DC to AC for the power supply to then convert back to DC.

But the only thing I've been able to find are these units designed to power electric doors: https://www.amazon.com/dp/B0D8VLPRN2/

I'm not sure if this would even be safe to use with a router, and i don't know how i would wire it up to the router either.

I think i just don't have enough knowledge to know how to shop for an appropriate DC UPS, or if such a thing even exists.

Anyone been in a similar situation?

The common solution is not to replace the UPS but only the battery inside. They are standard sizes and for a cheap UPS probably around 10 - 20 bucks.

THIS! Normally, the battery should be accessible via some door or a few screws. Replace the battery for a few bucks and you'll have 5 more years of peace.

This. My ups died after 10 years powering router and network. A replacement was $300 (for similar model) but the batteries were only $80. Just had to untape the pack and plastic adapter and transfer it over to the new battery set
