Re: [opensuse] UPS : replacing battery with 12 volt Jelly Car Battery
John Andersen composed on 2014-11-25 09:48 (UTC-0800):

Everything inside your computer (beyond the power supply) runs on DC.

With a DC supply, capable of generating 5 and 12 volts, you don't need
anything else.

You can power a 19 volt laptop from 2 car batteries for many days
on end. All you need is a LM7809,

9V??? How does that work? Did you mean LM7806?

which will set you back $1.95 plus shipping.

You're a lousy shopper. :-D My semicon source only gets $0.71 for those, if I
only want quantity of one:
"The wise are known for their understanding, and pleasant
words are persuasive." Proverbs 16:21 (New Living Translation)
