Can anyone tell me what happened to this jumper cable?

You can buy 400-600 amp hd clamps from most auto parts suppliers(used to anyway) and as mentioned buy welding cable to make your own. Not cheap but a lifetime purchase.
When I was in the auto parts bus I used to sell them like that to repair shops. The only draw back was, not ever wearing out ,but growing legs at an alarming rate.
A few years ago I bought some super nice cables made in USA from black and red 2/0 welding cable with super nice ends. I cut up one set for my old melt-a-battery special Snap-On charger and keep the other in my truck. They were about $150/set back then Iirc.

I was just trying to find the company I ordered them from to link here, but nothing is coming up. Anyone know what I'm talking about? Maybe they went out of business?
I was testing if I could heat up some steel enough to bend it using a microwave transformer with the high-voltage coil replaced with 2/0 welding cable, it didn't get hot enough but it definitely got hot. That's a stick electrode holder on fire and my clamp meter is out of range so more than a thousand amps [that burning coating on the electrode was really obnoxious/noxious]. I realized about making my own jumper cables a while back. The cable isn't cheap but you could make some fairly long ones for $150.welder-clamp-burn-1000+amps.png.jpg

I have a set of jumper cables (given to me) that came out of the American Airlines hub in Tulsa. I can't tell if they are 'shopmade' or were sold as a product but they are super-duty and well made. The only drawback is they are heavy and bulky....it's way easier to grab the Walmart-bought set.

I built my set of 20' cables from 1/0 welding cable and 800 amp clamps which I soldered together back in 1985. They will spin a motor much faster than the average K-Mart junk most people have bouncing around in their trunks. The only downside to these is sometimes I wish I'da made'em 5 feet longer, as reaching somebody's battery from directly behind a long vehicle from the opposite side can be a stretch...:D

You bought the cheapest, you left it out in the rain for years, and then you abused it.
I abused it after leaving it out in the rain? They weren't the cheapest, I was trying to get a decent set, they sure seemed to be well built, the clamps are quite good, and there was no indication they used Al wiring. It can't be just leaving it out in the rain, as mentioned, a good percentage of homes have triplex power lines with exposed neutrals so you'd expect them to routinely lose power, and I often see welders on trucks with their cables mounted exposed though I doubt the cables use Al. There had to be something unusual going on, that's why I'm liking the idea of the tannins from the oak tree. Would anyone here really expect this to happen from just rain? Weirdly, it couldn't be squirrels, in 9 years, I've never seen one around my property, which is near Canyon Lake in central Texas, so there's plenty of squirrels in the area, so no idea why I don't see them, plenty of racoons and skunks and occasional foxes and coyotes though, and one donkey come to think of it.

Well hell, I was some googling/wikipediaing and turns out tannins can be used to prevent corrosion on aluminum, so that's confusing.

Ah, yes, the old "I didn't witness it so it must not be true" defense. Did you keep those cords under watch 24/7, or just during the day when you thought the critters might get at em?

As far as hanging wires, yes they get rained on, but they're hanging out to dry with the wind blowing and they don't hold onto water, just get spritzed by it. Your cables on the other hand, were sitting in a pile of nasty wet oak tree leaves which stay wet once they get wet. It's a very different kind of "wet" when it soaks through the whole winter.

Might want to do a little more reading... That process appears to be used to break up the surface oxides and then afterwards a coating is applied. The tannic acid in that case looks like it is used to help that secondary coating stick better. Not just applied and left as a standalone surface treatment.

A lot of great responses, thanks everyone.

Oh yeah, another aluminum item that sits in the weather all the time is the neutral wire in the typical triplex cable that goes to most houses. I had no idea it was subject to corrosion like that, tannin from the oak leaves seems like a likely culprit, along with wicking causing the acidic water to soak the wires probably continuously.
My neutral cable in the power line was chewed through by squirrels. The PG&E lineman told me that the squirrels sharpen their teeth doing that.
He said that the company can save a lot of money by giving customers in a high-squirrel-environment air rifles.

I forgot the sarcasm tag it seems. It's not like they were on the ground or had leaves piled on top. but they would sometimes get leaves on top of them and sometimes were in some standing water but it would not last long.

The paper I found had this for its abstract:
This work aims at investigating the effect of tannin, a natural compound, as corrosion inhibitor for bare and coated aluminum alloys (AA1200). Tannin was characterized by Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (FTIR-ATR) and its interaction with the sample surface was evaluated by computational calculations using the density functional theory (DFT) and electrochemical measurements. The corrosion behavior was studied by open circuit potential (EOCP), electrochemical impedance spectroscopy (EIS) and by the scanning vibrating electrode technique (SVET). Complementary studies were performed by scanning electron microscopy (SEM). Results demonstrated that tannin is an effective corrosion inhibitor protecting both coated and uncoated aluminum samples.
This sure seems to imply it's the tannin that's doing the protecting. It's paywalled so I can't get to the actual paper. Here's the link to the abstract.

Weird squirrels. There might have been some kind of rodent damage on my cables but it wasn't squirrels. I'm near to areas that have so called crazy ants that love to eat electrical equipment but I don't think they've reached this area and I think they go for more for the service panel kind of equipment with active currents to warm the wires. It looks more like the insulation split to me but maybe not.

Without the neutral I had some damage to plugged in stuff. If you want to seek revenge on somebody, just cut the neutral wire on the house.
