Build a 48 Hour Backup Computer Power Supply - SYSTM

This clever UPS hack shows you how to replace the tiny battery in your current Uninteruptible Power Supply with a car battery. This gives you much longer life - as much as 48 hours. If you live in a power-challenged area, this is the best way to keep computing when the lights go out.

1. Average PC draws about 300 watts. UPS from battery would draw about 25 amps. using a 2 50Ah batterys you can get only 4 hours (or maybe even less if your PC is monster) :-(

2. UPSs are not designed for long operation under high load

That arc welding trick was really cool right next to the batteries and your face. Your lucky you didn't get a hydrogen flash with the arc so close.

generators take time to start up, a UPS switches to the batteries as soon as the mains power cuts off. How fast can you start a generator?!
