Dang, I thought that was a first. Who else did it?
To try out orange4boy's exercise the battery idea, I brought the battery inside. I charged it up, and right now its being discharged. I hooked it up to an inverter and its powering a 23W CFL. I'll cycle it down to about 11.5V and charge it back up. All the time, I'll be keeping it on a desulfator too. I did notice, in the Bentley manual I have, it says to use a pulse charger when charging the battery.
