Suspected cause
Looks like the current required will be a bit higher than I expected, since there is a good chance that the alarm will go off - I suspect few amps for a short duration - a pile of Nicads could do it in an emergency, but a donor batter would be a better choice.
Leading evidence: 'few amps' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'few amps' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace battery, you obviously have' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suspected cause
I wonder how much current can one put through the cigaret lighter - I think most chargers would be below 15Amps for normal charging - I suspect the hood release is just a relay, so no electronics are involved - any source close to 12V should allow for the hood to be opened, at which point one can jump start the car or use a high current ( 100A ) charger to get it going.

Suggestion
Well, in order to change the battery, you obviously have to open the hood.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Brought my friends to the dealer to show them the Cayman. The battery was apparantly dead from so many people looking at it. Well, in order to change the battery, you obviously have to open the hood. In order to open the hood, you obviously have to use the hood release. The hood release is electrical...
So, they pulled a panel by the foot rest to jump the electronics for the hood release. Then you jump the actual battery to do anything else. I'm trying to download the owners manual to figure out if there is another way to do this.
Weird huh?
P. 147:
"Important Note
If the vehicle battery is discharged, the front lid can be opened only by connecting an external electrical power source."
<Edit> Also look at p. 234 </Edit>
That's CRAZY!!!!!

That's the way ALL Porsches (other than maybe the Cayenne) have been since they went away from the manual hood latches in 2001. Nothing new to the Cayman.
As I mentioned in another posting, I am new to P-cars, so forgive the show of ignorance. Is there a reason that Porsche decided to go with a electrical latch? It's seems awefully inconvenient if you have a dead battery.
hsjb,
I am new to Porsche as well, my last one was in 1979 and yes I think that is weird and really inconvenient. I guess I better make sure I drive it enough to keep the battery charged.

So it's a frigid winter night & I make a late run to the grocery store. Park my Cayman & discovery the store is closed. Worse yet, my car won't start - the battery just died. It's getting really cold without heat, but no problem, I've got my jacket in the trunk. Oops. Death by design. At least the coffin has great curves.
If you think the Porsche hood release is a problem check out the new Corvette: you can't open the door if the battery is dead. There is one keyhole by the rear hatch and pull cords to manually release the electronic doors. There are also backup levers by the doors in case you are in the car at the time. This is progress?

Combine the no spare tire to the dead battery conundrum and you have a domino affect that could lead to some situations that you would not want to be in.
I went to buy a new996 Targa from a large US dealer that was on display. The battery was dead so the salesman went away to get a device to start the car, despite my protests not to bother. When he eventually came back he thought for a moment and then said 'do you know which end of the car the battery is in?'
I told him it was under the hood and that he wouldn't be able to do anything but he continued to try to open the hood.
I didn't buy the car.
I wonder how much current can one put through the cigaret lighter - I think most chargers would be below 15Amps for normal charging - I suspect the hood release is just a relay, so no electronics are involved - any source close to 12V should allow for the hood to be opened, at which point one can jump start the car or use a high current ( 100A ) charger to get it going. I wonder what factors pushed Porsche to use an electrical hood release - can't be cost saving - or can it ?
On Porsche's web site there are two battery maintainers listed.......one a pure maintainer, the other a light charger/maintainer I believe. Under the descriptions they do say they can be used to power the hood release when/if the batter is dead.
I just spoke to my salesman and asked obout this dead battery/can't open the hood issue. He told me there is a simple solution but it would take a large effort to explain on the phone and just seconds to show me how when I am there. Bottom line is that there are ways to open the hood and it should not be a big deal.
The procedure is described in the drivers manual.
You can download a copy from
www.renntech.org
(assuming you have registered).
It s the same as for the 997/996.
Page 234 of the manual covers the procedure. Looks like the current required will be a bit higher than I expected, since there is a good chance that the alarm will go off - I suspect few amps for a short duration - a pile of Nicads could do it in an emergency, but a donor batter would be a better choice.
Ahem, KenH please check this site, as the owner's manual has been available here for some time... /fckeditor/editor/images/smiley/MWPX/tounge_smile.gif
ps - they should consider themselves lucky it was unlocked - cause they're electical too - no key in lock won't do either!
err . solution is in manual - safely locked in car!
Keith
Are the locks really electrical? I thought they included a mechanical element so that you could openthe driver's door (only)with the key. One other issue to be aware of is that with no power the windows will not drop down, so the door has to be opened carefully.
The car I went to see last Fri. had the same problem. Salesman had it open in under 5 min. which includes the time to chase down the battery charger. It was simply opening the fuse cover,. pulling out the one for the trunk, hook positive to that, ground to door hinge and open trunk. Then he hooked it up to battey to start the car. WHOOOHOOOO got to hear it run in the showroom. Sure sounded better than the Boxster S I drove. That is making the wait longer still.
