    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!

    Doorstop.

    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.

    Don'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.

    I wouldn't risk my life, or my scope on it.
    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.

    "Am interested in all suggestions!"

    Guess I let myself open but will only respond to constructive suggestions.

    So far the only other use I have thought of is as a trickle charger for 12V gel or std lead acid batteries.

    While I can easily make up a set of connector cables was also interested in making a cigarette plug connector to use if vehicle's lighter socket is energized with key off.

    Has anyone tried anything like this?

    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.

    Make sure you charge some money for this of it works.

    Just sayin'.
     
  8. yeah, I learned that the hard way.

    huge bang and large cloud of smoke, then total silence.

    And some serious amps from the battery.

    12 volt 120 amp
    24 volt 60 amp

    Excluded efficiency yet.
