Thanks for the laugh, and man with organization like that you must have a big sock drawer. I go with the throw them all in one drawer and hope for the best approach.

I have the Perko OFF-1-ALL-2 switch and am having battery problems right now. What is it about the Perko that goes bad? If I end up replacing batteries, it does make sense to go with two starting instead of one of each. I only run stero, two radios, and two electronics.

BTW, what kind of batteries should I get if I replace them? Barracuda?, Exide?, some other brand?, whatever they have at autozone? What can be done to preserve my batteries? I do have a Guest onboard dual charger, but for the most part I only plug it in for 24 hours before each trip.

the perkos are ok, but they give problems after they've had some use, especially if you've tried to start an engine with a weak battery, The best tool you can buy for checking your battery system is a load tester, harbor freight has them pretty cheap, I use my load tester weekly to diagnose all kids of electrical issues

Thacker, your question prior to this statement about how to prolong battery life...IMO and my experience, yer missing the greatest thing about having the onboard Guest charger...the best way to prolong batteries for the long haul is to keep them HOT...and that's what leaving that charger plugged in all the time does...I had a Guest 2620 20 amp (10 amps per leg) on two group 31 AC Delco Voyager deep cycles used for elec trolling motor...those batteries lasted 9 YEARS and only failed after they were not left on that charger by the next owner...Batteries like two things...to stay hot and not be completely drained...mine stayed plugged in 24/7

I think that some one already suggested this already, but here is the link to the blue sea systems ACR kit. It is rated at 120 amps and it can parallel the battery's if needed to emergency start the motor.
This way you can just have a battery for starting and the other to run your electronics.

Or if you have a larger battery banks you can use this system:
