Uninterruptible Power Supply Power Backup for Home Recording Studio?

Have recently started a very basic home recording studio using older hardware in a rural area with frequent power outages. After a recent power outage am considering using a standard PC uninterruptible power supply to backup my old transformer recording hardware (already have one for my PC).

Before doing this thought would ask if I can damage this old equipment using a uninterruptible power supply (guessing the std PC uninterruptible power supply has a "dirty waveform" because could not find any info mentioning the output is a perfect sine wave).

Tried to search the forum using keywords "uninterruptible power supply" but only got "The following errors occurred with your search The following words are either very common, too long, or too short and were not included in your search: "uninterruptible power supply" When removed the "..." got Sorry - no matches. Please try some different terms.

Hope someone has either researched or tried this and has some suggestions.

Pop over to Wal-Mart, get a couple of their 12V deep cycle RV batteries, wire them in parallel with good thick cables (positive to positive, negative to negative), buy a decent automotive trickle charger, and then splurge on a true sine wave inverter. You want to be able to pull at least 15amp so your inverter should output at least 1,800W.
 
or...

I've been using a Belkin UPS for a few years now with no issues.
Had a few brownouts is all but it kept everything running smooth.
 
I doubt very much if decent modern electronics would object to the "modified sine" produced by most U supplies and inverters?

The stuff does not in any case draw anything like a sine current! Scoped the primary current of transformer just today drawing about 12watts for a guitar pedal and it is mostly positive 1/2 cycles and a spike!

Probably best to overate the supply by about 50%. Go round all the rating plates on your kit and have a tot up then add 1/2 as much again. Double it if you think more gear will be coming soon.

I would not advocate the use of any "wet" battery for heavy currents in a domestic setting. Shed, ok. There will be Hydrogen and other nasty things given off. It is also extremely bad practice to connect any batteries in parallel. You cannot expect the charge/dischage currents to be anything like balanced.
