Are battery backups surge protectors better than standard surge protectors?

[kndy]

Hi everyone,

I live in an area for some reason has quite a bit of occasional brown outs (and I'm not living in the country area either). These are the type that within a few seconds they flicker on and off several times and sometimes, down for a few hours. I lost a tv (that was plugged to a surge protector), a microwave and a few other electronics and the same with my parents television set this year because of these brown outs.

So, I figured I have a lot of my computer equipment plugged into a APC Tower and started having it in several rooms in the house but I often wonder if having one of those battery backup towers or batter backup surge protectors would be good for the home theater electronics or would it cause more harm?
