I'm not sure where you are located. In most places in the US (and I'm certain
of Maine and NH), building code requires fire-resistant construction around an
attached garage.

Hi,


What's your set up? What kind of UPS do you have?

Hey Ken, have you or anyone you know ever replaced the battery for
an UPS with just a lead acid battery (small car or motorcycle
battery)? You could just set it next to the UPS unit and connect it
with clamps.
You could probably really extend the time that your PC would run
during a power failure. The more powerful UPS units are very
expensive and I'm not sure that the main difference is just the size
of the battery or not.

Computers and regular UPS don't work on 12v DC current, they mostly
all run on standard household current. With a simple plug adapter
you can run a laptop on a car battery but you can't run desktop
equipment off automobile batteries. You would need to run the car
battery through a power inverter. And of course, like Ken said, who
wants a lead acid battery in the house?

John


Wrong John.
How do you think UPS systems work?

How exactly do *you* think that it works? If you think that you can run
a computer on 12 volts DC current, and if you think that you can charge
UPS batteries with a 12 volt car battery then you don't know how things
work. Unless specially built, the input requirements for almost all UPS
systems is standard household current.

Maybe your building codes are different, or not enforced. But there is an
International version of the building codes that also includes similar
requirements.

Not at all John. The UPS uses household voltage and it has a charger in it
that keeps the battery in the UPS charged up. When you have a power failure,
the UPS uses the battery inside to supply power to the computer (of coures
it must be changed to 115-120v).. The bigger the battery, the longer the
power will last during a power failure. This is what must be replaced in an
UPS every 3-6 yrs.
So, I was just thinking that if the battery inside is 12v then you could
probably use a sealed marine battery or similar and not only would it be
cheaper, it would supply power much longer during a power failure.
Of course you would have to do a little soldering, etc.

Criminy. Is this horse dead yet?

Think John, think. What is the purpose of the UPS? Supposing you lost your
AC power, where would you get the AC power for the UPS?

from personal experience the $150 or so investment in a ups is much
better than a fried pc / hd / whathaveyou.
i recommend a ups for all sensitive equipment, and surge protectors on
all other electronic equipment.

Oh for crying out loud! If you insist on running your computer off deep
cycle batteries then design your power supply solution around that,
don't try to mickey mouse a factory UPS to use batteries it wasn't
designed to use!

Why would one even bother buying an off the shelf UPS if they wanted to
use deep cycle batteries for their emergency power supply?

I think it's feasible and I was just asking.
Saving around $100 for a longer lasting UPS (how long it supplies power
after the main power is off) is still quite a bit of money for me.
Since I recieved no helpful replies, I consider it closed.
Thanks

To make the UPS supply power last longer during a black-out and because of
the software supplied with the UPS.
But never mind, I think we are talking about two different things.

PS: It's the size (capacity) of the battery in the UPS that LIMITS the time
it can supply power to the PC during a power failure.

The battery charger inside a $100 UPS is designed to charge the 5 to
10-amp hour battery that it is designed to use, do you seriously think
that it will be sufficient to properly charge a 100-amp hour or more
deep cycle battery? Do you think that you can properly charge a 100-amp
hour deep cycle battery with a 1 or 2 amp trickle charge?

Yes, we all know that the size of the battery will determine how long
the UPS can supply power. What you don't understand is that almost
everything in a cheap $100 UPS is woefully inadequate to properly charge
and maintain a 100+ amp hour deep cycle battery.
