Are all Boxsters especially hard on Batteries ?

you have this or a bad battery. I bought my battery at Walmart almost 3 years ago, I have left mine for 6 weeks and it still starts right up. Take your car to an Advance Auto or Auto zone and have them do a load test on your battery...this will let you know right away if it is the battery...these are usually free and only takes a few minutes

My '99 sits for weeks without a charger and all security on and starts right up. I also use an Interstate battery and will stay with them as the first one lasted over five years under the same conditions and only died because I had a faulty light switch that left the running lights on one day. You might check your light switch as they can be dodgy.

Went through four batteries before I read on here about the horn ring rubber grommets going bad and causing a direct continuous contact drain. If you replace the horn relay and the horn blows on contact then it is the ring. Very simple to replace with Wayne,s excellent book, and the part from Pelican was about 90 bucks. No more problems with the battery and my 97 has sat for over a week and started right up. Hope this helps.

+1 ^^^ Your battery should easily last a month without driving.

The alarm, clock, etc only uses a teeny bit of electricity and the battery should have more than enough capacity to sustain that draw for several weeks.
