Are all Boxsters especially hard on Batteries ?

[DrCactus]

My 01 Box S is very hard on batteries... I have to replace mine on average 4-5 years before it becomes completely dead. Just 2 weeks ago I was getting my E-test done and it died on the spot. I had to go get a new battery and I was back in business. After checking my paperwork it was about 4.5 years ago that I bought the last battery.

Simple.....I have mine on a Battery Tender all the time. I ran the wires from battery to the driver's side hood hinge and loosely secured it with a black cable tie (eliminates the need to lift the hood to connect and disconnect the Battery Tender connection)........same Interstate battery for 7+ years.
