Great idea! Now would that make Porsche an environmental friendly plug-in too?

 

Agree. I also have an Odyssey (it's a Honda minivan) and I would assume majority of these are driven daily yet many complain batteries lasting only 2-3 years. Modern cars are just hard on batteries as more and more electronics or computers run on them yet the battery technology has not changed much over the years.

 

If your GMC has less than 7,500 miles in 3 years, and it fires right up after a couple of months without the battery being trickle-charged previously, then yes, it must be an European thing.

As others have mentioned, 7,500 miles aren't enough to keep a 3+ year-old battery charged. A battery maintainer is your solution.

 

I just bought a new charger. I was all set on buying the Porsche one, but did some research and found that its just a re-branded CTek charger. The identical one that Porsche sells for $115, amazon has for $64! Its model US U3300. You'll have to pop for the cigarette adapter for $10 though. I went ahead and got CTek's top range the U7003 which is $115 but can recondition dead batteries and has a cell battery setting for Optima type batteries. Its a nice piece of equipment. Highly recommend.

 

Got the Porsche charger with cigarette adapter for free from my dealer when I bought my car.

 

Bruno - I am taking you with me next time I buy a P-car!

 

Have the B+ Cable checked. These are known to leak current and will kill a battery in a few short weeks. I used to be able to travel on biz for three weeks and come back without any problem, and then started having trouble after the car was 3 years old (already out of warranty - over 50k miles). Replaced the battery and still had problems. Finally the dealer fingered the B+ Cable. We replaced it and everything was fine again.
