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.

I installed a battery disconnect on my 2001 and used it for the winter months when I wasn't driving it. Worked great! Better to reset clocks than having to buy a new battery!

I purchased a Deltran "Smart" charger for my 2001 SE. I took the time to install the supplied o-ring connectors onto the battery. This allows the charger to be moved to use on another vehicle with the clip on connectors. This seems to be doing the job as my Miata starts right up.

On NC models, if you disconnect you will also have to reset your DSC. That will build up your biceps.

I have battery tender I will install before winter storage. I have the anti theft immobilizer package. I think you need a code to activate the radio...which I dont have. Even if the bsttery is dosconnected it should see a trickle charge at least once a month.
