Hack a UPS with a car battery

Hack a UPS with a car battery

Check out this Revision3 produced UPS Hack starring Patrick Norton! Take the tiny battery out of your Uninteruptible Power Supply and replace it with a car battery: you get to run your UPS for a lot longer, and potentially melt your face!

Uninterruptible power supplies are a great for maintaining power to a PC during a black out or brown out.

Unfortunately most UPS's pack tiny batteries that last just a few minutes before they drain. That's great for saving out files and shutting down. It's not so good for working on and on while the power is out.

Quite a few of you have written in about using a car battery with your UPS... we don't recommend it, but we walk you thru the project in this episode!

And, yes, we do have a Disco Ball ready to run on emergency power.... tho we really want to swap in a pair of deep cycle batteries before we leave the disco ball spinning all weekend.

Two or more lead acid batteries in parallel no matter what size they are (matching batteries or not) will discharge themselves over time. You are looking for a voltage of 13.5 to 13.8 volts to maintain a full charge in standby mode on lead acid batteries , gell batteries typically need a little higher voltage for standby charging which over time will evaporate the acid in a wet cell.
