Power conditioner plugged into computer battery

I would prefer plugging a power conditioner into a computer back up battery. At least when the electricity went out for a short time, the stereo system does not get shut down. Has anybody found out that the typical computer battery/surge protector limit the amp current or create other sound problems. If yes, is this true across all conditioners or that certain ones manage to be immune. Thank you.

Thank you for asking this very question as I have been thinking about this the last couple of days. I have a Pass X1 pre amp and a Pass DAC 1 that do not have power switches, so they are always powered on. In a recent power failure the DAC 1 got fried. Pass Labs fixed the problem. It sure would be nice to have a back up battery on equipment that can't be turned off to protect from these situations. APC seems to make new conditioners / back up batteries for audio equipment. Anybody know about these products?

I have used Tripplite line conditioners and UPS.. and even an APC UPS but they make an audio system sound awful!! I used a Tripplite LC1800 and it still limited current. The sound was totally closed in.. and worse yet the power switch went up in flames one day... and I threw it in the garbage..

DO NOT DO IT!!!

There are plenty of audiophile conditioners that provide surge protection for you DAC's and all your other gear so you don't have to worry and more importanly when you get one with isolated outlet banks that filter out the Digital components artifacts on the AC from your Preamp and amp.. this is a huge benifit in sound... I still prefer amps plugged directly into the wall.

I use an APC H15 (non battery backup) in my HT and it works great. It does not limit the current to either mt B&K
receiver or ART of Sound sub. It enhanced the video picture also. With voltage regulation and surge protection, it has been terrific during thunderstorms. I'm looking for another one for my 84 year-old mom's system (Marantz, JBL/w AAD sub) which currently is hooked up the way this post originally stated. Everything is plugged into a Tripplite Isobar which is plugged into an APC UPS with battery backup including the kid's computer. For my analog rig upstairs, I use a Brickwall 2AUD.

APC recently introduced a series of power conditioners specifically designed for audio/video applications.

Their "S" Type AV Power Conditioner with Battery is pretty much exactly what you are looking for: "Pure sine-wave battery backup, surge protection, isolated noise filtering, and voltage regulation all combine in a single unit to deliver pure, uninterrupted power for high performance AV, home security, and automation systems."

I have been running its little brother - same without the battery back - since November and am very pleased with it. The system sounds very, very good...
