OK, as some of you might know I am currently without any power whatsoever. However I do have a laptop and a car adapter for said laptop. I mean direct DC-DC not an inverter. I have the wacky idea of grabbing a car battery cheap and using it with this adapter to provide me with much longer usage at my home. Now i have a trickle charger and wouldn't mind letting it sit overnight next door to charge now and again.
So how long would a car battery last, is this nuts, and should I even consider it. For the record the power will be off here another 3 weeks.
