Harbor Freight Battery Maintainer Mod
I have a TT that I store at a remote location during the winter and I bring the group 31 AGM battery home with me. I have a charger to ensure that it is at 100% SOC before it gets set in the corner of...

Could someone on here give me a lead to a description and maybe a part number that I can pick up a diode? Or can I just go to my local Radio Shack and pick up any 1A diode from their parts drawers?
You don't need to use a Shottky diode… I just happen to have a bunch of NTE578's and this type of diode is suitable for the job.
However, if you have a RadioShack store nearby I suggest that just get a plain ol' (read: cheap) 1N4001 diode.
Keep in mind that if you choose to add the diode then you may also need change the value of resistor VR1 (alternatively you can add the 100 Ohm trim-pot as I have done), otherwise the voltage drop (~0.7V) across the diode may cause the charge voltage to be too low (depending upon your desired float voltage of course).
