Battery Charging Problem
I recently purchased a 2005 Boxster and don't drive it in the winter. I bought a CTEK Multi US 3300 Battery Charger which is the same brand as the Porsche charger and use the cigarette lighter adapter. It doesn't appear to be charging as the partial charging light indicator light hasn't moved to the fully charged indicator after a couple of weeks of charge. Do I need to do anything else? Can I connect the charger directly to the battery terminals while in the car instead of using the cigarette lighter adapter? Is there anything I have to do to safely charge the battery?
