Default 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.

Why not just take the battery out of the 2nd one and put it in

efficient.

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.

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..

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.

Has anybody tried getting longer run times from UPS's by plugging
one UPS into another?


Power goess off, the first UPS goes on batteries, and runs everything.
When it quits, the second UPS senses it and goes on batteries, and
runs the computer.


And so indefinitely if you add more UPSs to get more runtime.


It seems it me it would work except possibly :


(1)The UPSs might not like the non-sinewave output of the first UPS, and
(2)I don't know what kind of current they draw if they decide to
recharge their batteries from an outer UPS. (This would suggest it's
wise to unplug the outer UPS when the power goes off so nobody
tries to recharge.)

You're not going to extend your runtime near as much as you might think.
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!!! I use to sell them

Yes most likely the next-size-up UPS will cost less than
the two smaller ones and be the more Reliable and Co$t
Effective $olution to the Quest for Longer-UPS-Run-Time.

the bigger one is the better one : when the alternative is two
of lessor potential and twice the possibility of failure ~ RHF

Is there a UPS that explicitly uses external (auto or marine) batteries?

What's On Your Power Grid :
UPS ? -or- Alternative Power Supply ?

Maybe the Philosophical Question should be . . .

WHY USE AN "UPS" ?

* Do You Use and UPS ?

* Why Do You Use an UPS ?

From 'my prespective' living at the End-of-a-Country-Road.

I use an UPS to Safely Power Down the Computer and
wait, Wait. and WAIT ! until Full Electrical Power is Restored.
When the Lights Go Out and the UPS Beeps and Lights-Up
that It Is "ON" {Working}. My actions are simple :
1 - Close Down the Compluter Applications
2 - Power Down the Computer
3 - Turn Off the UPS
4 - Check the Emergency Lights
5 - Start a Fire in the Wood Stove
6 - Turn on the Radio and Listen to What's Out There ! ! !
- - - When the Local Background Noise is Ever-Oh-So-Low.

BUT =IF= What You Want Is an Alternative Power Supply
that will Run your Computers for Many Hours and up to a
Day. Consider some Deep Cycle Storage Batteries and a
very good Solid State Inverter.
