Have an Uninterruptible Power Supply (UPS) with dead battery and do not want to buy a new one so am interested in other uses.
Am interested in all suggestions!

Don't expect to use it as an emergency inverter with a car battery.On Fri, 30 Nov 2012 09:53:01 -0800 (PST), KenO<kenitholson@yahoo.com

Chock behind the wheel of a car when jacking it up.
The power cord makes an adequate disiplinary device.
Give it to Goodwill.
If the shape is compatible, use it to raise a flowerpot off the
ground.
Heave it at the next missionary to come to your door.
Wrap it up in Christma wrapping and leave it a visible place for
someone to steal.
Buy a battey ( less than $20) and use it as a UPS.

Recently I was pursuing an isolation transformer, until I read a comment
of using a UPS in place of one. All one would need to do is remove the
A/C plug and operate the test device from the UPS. I often face this kind
of problem with a scope when troubleshooting a device.
I wouldn't risk my life, or my scope on it.KenO wrote:

Make darn sure the one you have is completely isolated.
Modified sine wave is sometimes a hindrance to debugging a power supply.
I forgot to mention another downside of trying to use a UPS as a general
purpose inverter or isolation transformer.
Some UPS's can't be manually started. You have to supply AC then remove
it
to get it to run.
at anything like rated output. I actually use a 150W unit as aDon't expect to use it as an emergency inverter with a car battery.
The heat sinks are rarely able to dissipate the heat of a continuous
load over long periods.
And some serious amps from the battery.OK, as to the OP, use it as a PS for an audio amp, but rectify the output directly, no more tranformers. Should be able to get plus and minus 150 or so. Feed that into some nice hefty pitput transistors and make the streets quake.
150*.707=106.05*106.05=11,246.6025/8=1,405.8253125 watts RMS
That is some serious power.
yeah, I learned that the hard way.On 11/30/2012 11:22 AM, PlainBill@yawhoo.com wrote:
