Has anyone used a full-system battery power supply?

It seems to me that the biggest problem in most high quality hi-fi systems is dirty power. My AC power in Vermont is weak and dirty. Has anyone ever heard of a massive battery power supply that could provide power to a whole system? Rowland uses them, and there are some newer phono preamps that use them. I am not very technical, so I don't even know if this is technicially possible. I have owned a PS Audio P300, and I didn't feel that it gave me $1200 of improvement. I also owned a Custom Power Cord Co. power conditioner and heard no real improvement--just minor differences. I owned a battery powered Camelot phono stage which was great until it crapped out in two weeks and I had to return it. Any thoughts on this mega-battery power supply?

Perfect: defense industry contractors make the best. Used in submarines & the like. As you note, you plug them in & the equip in them. The amperage is not always very high, though. The ones I've seen are HUGE, ugly, best left hidden somewhere...

In Europe they come reasonably cheap: ~$1k for a 12amp that can last 3-4 hrs unplugged. Maintenance every 2-3 yrs.

Never tried one -- maybe I should.
