As a $13 alternative, you could just attach something to the (+) post.
You'd have to seal off the open connection somehow.
With that, you could just use traditional jumpers snice the (-) post is not blocked.

Then again, Walker's vice grip trick accomplishes the same thing for free.

you can seal off the positive end of a cable like ^^ with a large vacuum cap.

Sugarwood -- while I don't have the same jumper set as you, I've had no real issue using several sets of jumper cables on my 911 battery - could be the orientation of the positive cable? My 911 is currently at the body shop, but if I recall correctly, the bold that secures my positive clamp to the battery was oriented toward the front of the car, allowing me to (relatively) easily clamp across the bolt on the positive terminal.

Good that you did a dry run with yours before getting stuck "in the wild" -- do you have other cables that you could also try? This may be specific to the new cable set you just bought/received (?)

You're such a tool. Next you'll be asking how high the car has to be off the ground to change a tire.

"Wait a minute..."

Your best bet is to call Triple A. They'll have you jumped and on your way before you figure it out.

last time you resorted to name calling shug you were banned for a few weeks.... it was a great couple weeks around here...

That's very strange that you were able to jumpstart your 911. There there is no physical way to attach jumper clamps to the (+) terminal b/c of the unique battery location of the 911.
Go check your battery. The (-) terminal should be towards the front of the car. The (+) cable does not have enough slack to reach the front of the car.
The only thing I can think of is that your battery posts are transposed. Is your (+) terminal on the inside or outside ? As you can see in post #2, both styles are manufactured. If the post is on the inside of the car, closer to the gas tank, then it is not blocked by the fender.

I've jumpstarted dozens of cars over the years.
Not one had terminals blocked like this.
It's obvious you don't grasp the gist of this conversation.
Kindly get lost. Better yet, put me on ignore and FOAD.

Good effing grief..Did you ever think you might loosen the battery, get your jumpers attached vroom vroom.. get the battery back and bolt it down?

Pretty much...it is a soap..

Sorry, but there is no slack in the (+) cable.
Do you think you're going to rest it on the gas tank? Sorry, no slack.
Do you think you're just going to hold it in mid-air ? Sorry, you need to go turn the key.
On a 911, you can not move the battery while the (+) cable is attached.

Well thank you. Just trying to pass on something I have learned that maybe others can benefit from. Lord knows I have learned far more from this site than I can ever hope to contribute.

To your question of charging.....I have a battery tender brand charger, and have their wire attached to the battery cables with ring connectors. When the car comes in I just plug the plug into the wire for the battery tender. This allows me to charge/top up the battery just bu opening the trunk and attaching a 1 way plug. Simple. I use the cables I sited earlier for jump starting only. I have found this to be about the best setup.

two (three?) projects ago, I had a car that was nearly impossible to jump start. if i had to jump the car, i would connect the jumpers directly to the starter and the cylinder head as i ran a Harley Davidson AGM battery in the trunk. after doing that one time, i installed the ring-terminal end of the charging cable permanently to the battery so i could throw it on the trickler when it was going to sit.

a jumpers set with a quick disconnect in the middle like you shared would have been excellent. my thought for jumping/charging is that an additional connector could be wired to the end of the charger and then all aux electricity would be channeled the same way.

Can somebody post a picture of their battery in their car?

The underlying assumption in the OP's post is that all batteries in 911 are configured like this.

Maybe some pics would help.

Sugarwood, have you loosened the hold down clamp and tried to move the battery towards the center line of the car? Your picture is not clear on the positive end of the battery with respect to clearance.

Something is wrong with the battery placement or size. OP's picture shows no access to positive terminal. If this were the same across all 911's there would have been products made to remedy by now.

Here’s how to jump a car on a dark night with no light, few tools, just know how. I have to tell a true story from earlier in the semester when I was stopped by four kids, actually blocked on a think dark road coming out of east Osaka at 930 pm. I teach sports kids on that night at Kindai University (formerly known as Kinki University as up to two years ago, but they changed the name from then for obvious reasons – couldn’t get any international students.) It’s the biggest educational institution private or public in Japan. Kids in my class are from any sport you can imagine, all sports. They train all day, have to study at night.

Now, these 4 kids weren’t from the KINDAI University but had come there on another event. Battery dead, they flagged me down and it was odd and suspicious. They asked me if I had jumpers, I said oh yeah, but they are in my garage at home. Oh! They said, don’t worry, we’ll just ask the next person that comes by. I paused, knowing that no car would come by on that dark thin street after 9:30 at night. Long story short, I said show me the battery, then I took my battery out of my van with my tools within two or so minutes. Took it over to the car, told one student to shine his iphone light on the batteries, another to hold the battery sideways, A third student I told to hold the key in the car on start position wherein I simply put two spanners on the posts both ways positive and negative. As soon as I did the car started and the kids were over the moon. I had my battery back in my car within two minutes and was on the road. The whole ordeal might have lasted 10 minutes from the time I was stopped to the time I shipped off. Now that is how you start a f-cking car! I just had to share this true story after seeing this thread for the first time.

Great post, Bob, as usual.
No, I did not loosen the battery. Why?
I simply attached a trickle charger and went to bed.
The next morning, I went for a nice long XMAS drive across state lines.
I will try moving the battery, to see if the clamps then fit, for the sake of documenting this archive.

But, the premise of starting this thread was to figure out how 1000's of 911 owners have jump started their cars "in the wild" over the years.
My assumption is that you will not have an extension bar and hex socket bit to move the battery. So, as it sits, it's impossible on the road with only jumpers.

So, your other questions are the crux.

I use a size 48 battery. Pretty standard.
Maybe AGM batteries have their posts inverted to the outside?

I would love to see photos of other 911's battery bays.
How many people here can attach standard clamps to their (+) post?
Snap a photo and maybe we can get to the bottom of this mystery, as Bob posed.

That's awesome. But, how did you get the spanners to stay put? Were they balanced delicately ?

1st I understand the question as there are many folks in this world that are not real handy or lack hands on experience(not me)

I can tell you that over the ownership of 6 different 911s I had on occasion had to jump start one of them.. I never found it to be difficult. Just had to lay the clamps at a 45 degree angle..

Here’s my battery set up- I believe it is the “factory” large size Interstate replacement. I do have aftermarket ends with posts from my car stereo days and could probably get jumpers on the terminals, although I can’t remember every giving or receiving a jump in 28 years of ownership- I know there were a few push starts over the years.

Not delicately at all, just muscles in my arms, you know hands, forearms, biceps and maybe tricepts? I don't think I used my pecks. It was a hand job if you will, but it only took a second once the parties were in place, and they only took seconds because they were attentive students.

I don't think you understand the question. Jumpstarting a car does not require strength. You said there are 2 spanners connecting each battery post. Obviously, there are no attachments or clamps. How did you attach them? Are you saying you held the naked spanners with your bare hands while they jumped the car. Can't you get electrocuted like that? Isn't that why jumper cables have insulation? If you do not hold them, then how do they stay attached? Did you balance them on the posts? Is that more clear for you? Isn't it the height of stupidity to hold the spanners with your hands while the battery is cranking?
