I own a 2008 Porsche Cayman that sits in my garage for 2 to 3 weeks between drives. Although I was told to use a battery maintainer or risk getting a dead battery, I did not. Well, I learned the hard way and my battery did in fact die. It cost me $400 for Porsche to replace the battery and test the system. I immediately ordered this item to prevent such a thing from happening going forward. It is very simple to use...plug the charger into a standard wall outlet, the other end into your cigarette lighter outlet in the car. The wire is so thin that you can close the door without kinking the wire. I highly recommend this product to avoid the same costly mistake I made!

Buy Porsche Battery Maintainer Now

This purchase was made once I realized that it was not at all convenient to use a conventional battery charger on my Boxster. The fact that it is a maintainer and will not overcharge the battery is very important to me. I have been using this product for a year now and find it to be a great choice for its intended use. It would get a five star rating from me but as with anything Porsche, it is way overpriced.

Paid the premium to get the Porsche brand to ensure quality proper charge for the vehicle. It simply quit working after a month leaving me with a dead battery -the absolute kiss of death to anyone with a Boxster given the issues associated with battery access. Hard to imagine a more simple electronic device. Poor quality control. A real disappointment.

Porsche recommends this if you are not driving at least 5-6000 miles per year. If car sits 4-6 days often it is a must.

This was half the price of Porsche dealer price. Works great

It is simple to use and works perfectly. I would recommend it to others who need to maintain the battery on a vehicle that's not driven very often.
