Battery backup

I have a Sony Wega 51, TW Exlorer cable, and Onkyo reciever and want to buy a UPS so when the power goes out briefly this stuff doesn't keep shutting down. I'm not trying to keep this stuff up and running for more than a few minutes just something to bridge the gap. Anyone have any suggestions on watts, VA's etc.

no info other than...

as with ALL BATTERIES, no matter what type...

they have a finite lifetime... they will not last forever.

Therefore, anything with a battery will eventually need
a replacement battery.

all i have to say...:hithere:

I have had very good success with an APC Smart-UPS 1400 (current model is the 1500). The APC Smart-UPS line of backup power devices actually produce a pure 120v sine wave output when on batteries, not the typical "square-wave" output of less expensive UPS systems.

I live in a semi-rural (it used to be rural, but not anymore ! ) area and we have a "power event" about once a month. We also experience "sag" low voltage events during the peak A/C months of the summer and the APC Smart series has voltage boost capability as well. In other words, this line of backup power systems is both a voltage regulator, surge protector, and backup power system. The 1400 volt-amp ( about 950 watts) backup capacity gives me plenty of time to turn off the a/v equipment in an orderly manner if the power event is more than just a transient.

I choose the UPS with sine-wave output because many transformer based electronic devices tend to overheat when supplied with square-wave current. Computers, with their switching power supplies, don't mind square wave at all, but most a/v equipment has transformer based power supplies.

you can find good pricing on these units by carefully searching the web. I bought mine off ebay, but that can be risky with used equipment. I purchased these units for work from www.refurbups.com

Plan on replacing the batteries about every 2 years.....maybe 3 at the max. We rarely get more than 3 years out of a set of batteries and no longer even try. Critical UPS batteries are just replaced at 2 year intervals.

I ended up buying a Powercom 1500VA and it definetely seems to do the job. After charging up the battery I uplugged the unit and everything kept running fine. TV, Amp, and cable box.
I have no idea about square waves and I'm sure the APC would have been better but my wallet just couldn't do it. I got this UPS for about $150 delivered which looks pretty good.
My advice to anyone who has shelled out a few thousand dollars on a TV get yourself a decent UPS. No way can all these power surges be good for this equipment.

I liked the Belkin PureAV Home Theater UPS with AVR Technology Get them from my Dell rep for 149.99 shipped so I ordered two :)
