Re: Cayenne S Hybrid Battery
I imagine you may be using your SUV for commuting purposes too - it's not easy to rack up over 20000 miles per year 
But at least the advantage is that the car is being almost daily and heavily so the battery gets a really good charging from the alternator.

Re: Cayenne S Hybrid Battery
I called Porsche NA and they said they do not know and it could take months before they find out. I also called most dealers here in southern California and they are all giving me answers fthat the battery will last 10 year or 185,000 miles, every 70,000 miles, lifetime of car ect.... So if anyone on the board has any connections with Porsche could you please let us know what the actual life span of the Nickel Metal Hydride battery lasts/
Re: Cayenne S Hybrid Battery
I'm thinking you may not get a definite answer to that because there is no definite answer. The life of the battery is going to vary with the way it's used, the climate where you live, etc. What you should be able to get is some idea of the average life for the battery though. Maybe it would be helpful to see what other hybrids using this type of battery are experiencing. Are the Prius and Insight using the same type of battery?
Also, what about the warranty? Is it just the 4 year 50k mile warranty or does Porsche have an extension on the battery? I seem to recall some other hybrid manufacturer was offering an extension on the battery warranty.
Re: Cayenne S Hybrid Battery
I've been doing some reading. Hybrid batteries last a long time. Both Toyota and Honda warranty their hybrid batteries for 8 years or 100k miles. Both use NiMH batteries. If you buy any hybrid vehicle in California, or any state that has adopted California's auto emission regulations, your battery warranty is 10 years or 150k miles. There are some Prius owners that have driven their vehicles over 200k miles without a battery replacement.

My kids were driving a 2004 Honda Civic Hybrid for a number of years. Its NiMH hybrid battery got "soft" after about three years where its capacity to absorb a full charge diminished substantially. The effect was to have very short lived electric boost and refuse to climb hills without slowing down or having to buzz the engine. No lower register torque past a few seconds after calling for it. Night and day difference from new. Almost dangerous in traffic.
Being handy with electrical things, I diagnosed the problem and took it to the dealer for a fix. Honda of America refused to replace the hybrid battery unless the "check battery" light in the instrument cluster was illuminated. I told the dealer that if that were the case I would just sell the car and be done with their hybrid stuff. The dealer offered to lie to Honda of America about the light being on. Nice of them. But, they couldn't get a new boost battery delivered from the central parts depot in time to fix the car before my kids left town for college. The dealer ended up giving me a descent trade in on a Honda Fit and it will be a while before I trust a Honda hybrid battery warranty again.
Honda, of all companies! Who'd have thought?
P.S. I'm driving a PCNA-supplied Cayenne Hybrid to evaluate it for a presentation on Saturday. If anything interesting comes up, I'll post some more details.

Re: Cayenne S Hybrid Battery
There is apparently a lot of Civic Hybrids with dying batteries, and as Mike said, Honda is very reluctant to replace them unless they are completely dead. Many owners are experiencing the exact problem described above. Honda has issued a software fix but many owners are complaining that the fix both reduces performance and increases fuel consumption. The California Air Resources Board is now investigating. See the link below to an article in the LA Times about this story:

Re: Cayenne S Hybrid Battery
Make sure you have deep pockets, my cayenne hybrid only 6 years old and 93000 miles and hybrid battery is knackered and they want over 7000 GBP to fix it. Seriously sub standard battery on them and really dangerous when it goes as all my electrics and engine cut out and seriously put me at risk. Would be petrified to drive kids about in it when this is the result #porche #porschecustomercare no help at all even though dealership has admitted this is more than poor
Re: Cayenne S Hybrid Battery
A good friend of mine has an 10 year old Lexus GS Hybrid - last annual check it still had 90% battery capacity.... serious bad quality from Porsche! I think I would try for a sympathetic claim if you haven’t already!
