Vance,
I think that a float-type charger is what you want. I think that these are a little "softer" than some trickle chargers, and you don't risk boiling out the electrolyte.
Maintenance chargers are the best thing that you can do for your battery when storing a car for more than about a week. Lead-acid batteries like to be fully charged all the time. If they run down, their plates sulfate and you will never get the same capacity out of the battery again. I am a believer in trickle/float "pulse" chargers: The pulsation of the charge effect can remove some sulfation from the plates and keep your battery in top shape. Besides Porsches, I also collect antique fire engines. These can sit for a long time between events. I got tired of replacing 8D size batteries (big ones!) at about $150 each, and set up maintenance chargers on my rigs. Haven't replaced a battery since. I personally use and recommend the BatteryMinder charger. I get mine from batterymart.com, as they have the best prices I have found. No financial interest in either company, just a satisfied customer.
BTW: I have never been pleased with the quality of anything electronic which I have purchased from Harbor Freight. Keep an eye on your car to make sure that the HF unit does not boil electrolyte out of your battery or it is toast.
Good luck,
Tom
