Hi,
I have a 2009 Cayenne GTS with a manufacture date of August 2008. The vehicle was put into service April 2009, and has been in the SoCal area the entire time. Does anyone has a suggested replacement date, (preventive maintenance action) and type of battery which could replace the OEM item? The current battery is working fine today, just don't want a dead bat tomorrow.

Thanks,
Brad

 

I personally do not preventatively replace battery. If the crank at start up is getting weak, then I replace my battery.

You don't have to worry about cold start where you live, which definitely needs a lot of cold cranking amps.

How long your battery lasts depends on so many things. Short drives, using a lot of electrical accessories, temperature fluctuation (even in hot climates) all shortens battery life.

 

Well said. I suspect the life will be extended using a trickle charger if car has many short trips and especially if sits more than one week.

 

I proactively replaced the battery in my MY08 Cayenne a couple of months ago since it was over 5 years old. Since the cost of the replacement was under $200, it was not worth the risk of getting stranded somewhere and having to call a tow truck.

This makes me think of the proverb "An ounce of prevention is worth a pound of cure" .

 

The stock cayenne batteries, while pricey, are solid. Seriously, in my area, which is southeast U.S., typical replacement is around 8 years or so.

 

As already said, how long a battery will last varies widely based on how it's used. However, the standard replacement interval is 5 years regardless of mileage. Since replacing the battery is pretty inexpensive and easy to do, I'd just stick with that and throw a new one in there.

As for what to replace it with, I'd stick with the Porsche OEM unit. I've tried smaller/lighter batteries which were also cheaper, but I was most concerned with weight since the OEM batteries are over 100 pounds versus 60 pounds or so for a non-OEM battery with sufficient numbers/stats. However, Porsches in general use far more battery energy than other vehicles, including when they're off/sitting, so you could easily find a dead non-OEM battery in the vehicle if you parked it at the airport for two weeks. So you can get a battery for half the price, but at under $200 for the Porsche ones, why bother when it's only costing you $40 a year?

 

For what its worth, the wife's '09 G37 Journey, almost daily driven with a long commute, just had to have the battery replaced. Went with an Optima, one of the top rated by Consumer Reports, $229 or so.

I called around for the top-of-the-line Interstate and no one open (on a Sunday) carried. It was an Absorbed Glass Mat unit.

Seems that some cars will still have full dash displays & bright lights and the battery won't start the car.

 

Regardless of warranty, some batteries will fail in a year or two and some will go maybe 5 or more years. If you get 4 years consider yourself lucky. The Optima might be a little better. Neglecting defects, life expectancy all depends on operational temperature and the number of times you drain the battery. The "Diehard test" of running it way down is very hard on an auto battery and should be avoided as much as possible. Defects can also cause early failure. Be happy if you get 4 years out of a battery in an area with high or low temperature extremes.

 

06 CS owner here...Still have the original battery without any problems

 

Either you are as fortunate as a Mega Lottery winner or you live in a very neutral climate. Consider yourself lucky and/or exceptional in either case. But yours is not the typical battery life story...

 

Mine was about 7 years old when I replaced it. It was still cranking fine - I just replaced it as preventative maintenance. I have to think that the placement of the battery inside the truck helps with longevity.

 

+1...

 

Battery ambient temperature is a major factor in life expectancy. It.is the primary reason electric utilities air Condition their control houses.

 

2006 Cayenne Turbo S in Minnesota (95 degrees in summer, -20 in winter, heated garage at home, daily driver) still going strong with original battery.

Although there are many variables, our 2009 VW Tiguan battery died in December 2013.

You never know . . .

 

Just have it checked every 6 months (or so) at your oil changes. My dealership does a full inspection with every service.
