UPS in series?
www.devilfinder.com APC Model 1000
is what I use.My Velocity Micro ProMagix tower computer and NEC Multisync 22 inch flat screen CRT computer monitor are power hogs.When the power goes out here due to stormy weather,I shut my computer down and wait a while.Sure,laptops don't use much power,but I have no need,nor do I want a laptop computer. cuhulin |

It would be, but there's a catch. When the time comes to recharge the now much bigger battery, the original charging circuit probably couldn't handle the extra current. The greater the plate area, the more it starts looking like a short circuit as far as the circuitry goes. Most things being now built are made down to a cost instead of up to a quality standard. mike I've done this succesfully. I'm guessing the current is clamped, but the Triplett kept 3 big-ass batteries charged in a microwave shack. You obviously have better taste in the UPS systems available. I tried a large 12V sealed lead acid battery once and the charge circuit DID melt down. I was heartbroken. My visions of a two day standby time were crushed. The small Tripp Lite I have now is acting up. The relay used to transfer standby power over doesn't work anymore. In all fairness it is an older 450 VA model, so I should really look around for a new one. I should also do a complete back up...today...right...today.. mike |

Buy a new battery back up device.Tripp Lite,APC,or whichever brand name
you prefer.When the batteries (I think my APC Model 1000 has two batteries) in my batttery back up get too worn out,I will go to a local computer store and buy a new one with new fresh batteries in it.I won't mess around.By the way,I get snail mail APC pamplets in my snail mail box,whenever APC company sends them out.I guess a www.devilfinder.com for,APC News Letters might turn something up. cuhulin |

If you had an UPS with a clean enough pseudo-sine waveform to even get the next one in line to power up stably (and you have to get into some very very good ones to do that, they basically have to be generator rated), then you have to deal with the issue of the other UPS'es in the chain not being 100% efficient, so you lose a lot of what you would have gotten from that first unit in the line. This of course follows up the chain. Just buy a bigger UPS!!!
