Think of your battery as a bucket of water and the alternator as a small facet. Now all of electrical components all take some "water" out of that bucket and the facet tries to keep it full. I don't know about your car but I have heated seats, Bose amp, electric windows/mirrors and seats, deployable spoiler, all the electronic hardware (ECU, ABS, PSM, fuel pump) and the convertible top. I'm sure I missed a few things but thats allot of drain on a battery. It's all about electrical capacity. Don't forget your putting a strain on the alternator trying to keep up...if you have a small battery.
I feel if you want to save some weight in your Boxster, go on a diet. Don't sacrifice you car.

No need to go on diet...I bought midtronics PBT-300 to test the battery just to avoid having to go through a diet. That way you'll know for sure how much electricity that your system eats and how much power that the battery has.
Porsche Tequipment charger also seem to do its job everytime I leave the car in the garage for more than 3 days. It gives me a peace of mind and I don't think I can live without it!
