How to prevent dead starting battery in storage?

Thanks guys,
I think I will check into the Trik-L-Start solution. I managed to locate the emergency start solenoid on my rig so should be an easy hookup. And it would be a permanent solution.
Also, I plan on using the rig a lot more this year.

Looks like my battery may be alright. It's showing 12.45 volts after charging and sitting overnight. Time will tell.
