Make that 5 minutes * 500W/5W or 500 minutes which is indeed a long
time but a lot shorter than the 150 hours you were expecting.

If you want 150 hours, you need to be looking at a backup generator, so your UPS only needs to last as long as it takes for your generator to fire up.
That's usually a couple of minutes for professional diesel ones, but as its home setup it might take you a few minutes to connect it up and pull the starter cord on a cheap petrol one.
It might then take a few more minutes to drain the tank of the sludge that used to be fuel last time you used it, and to run to the garage to get some fresh petrol.
It might take a few more minutes if your spark plugs have been fouled as you didn't clean it after use, and your air filter has a hundred different types of bugs living it.
So make sure the UPS lasts an hour or 2.
Oh and once you've managed to get it going, and it's making a tremendous racket, just remember everyone else in the neighbourhood who is without power will be turning to look in your direction...
