Gentleman,
Has anyone installed a battery disconnect switch to avoid the battery drain problem? Will continuously disconnecting the power supply do anything other than loosing radio presets? Thanks!
Jim

since my car is in a garage with electric outlets, I attach a very small (1 amp) battery maintainer for winter storage. You could incorporate a two pin trailer light connector and some ring terminals to permanently connect to the battery. My maintainer turns on at 14 volts and delivers a very small trickle charge.
If no power is available (outside storage), you might consider a solar maintainer. These plug into the "cigar lighter" outlet in most cases. In my case, during the months when the car is in use no maintenance is required. No lost presets.

I too have used a battery minder (smart charger) for cars not driven often. C-Tek makes a nice simple unit available on Amazon last time I checked.
