UPS, and i don't mean shipping

Hi folks! i got my hands on an old big UPS that was used for a computer server. It's the old kind that had batteries on line full time. If i'm not mistaking it first converts AC to DC, feeds it to the batteries and the output of the batteries is converted to AC again. Wouldn't this unit make a great power supply noise filter?

Has anybody tried it? The batteries in it are dead and i'm wondering if it's worth replacing them. The damn thing is quite noisy but i plan to install it in the garage and run a cable to my living room.

Thanks for any advice!

You could make your own. Those thing are only a power supply and some batteries. Like 30-40 dollars worth of parts. And then you could get really nice big batteries and power supply.

Well he could also have it that he runs only on batteries and switches the power supply off when listening. Not quite sure how long you might have without running into some money and a big row of batteries, and regulation as Mr. Aball has said. Then again with just the batteries I don't see it very difficult to convert your system to accept the DC. It is that DC/AC thing that is the tricky part.
