I once made a deadplug, I was kinda distracted and ended up with a cable with two male plugs. Hangs on my shop wall as memento for "focus on what you're doing" or something.
You can also get that from just the label.
The CCA rating (cold cranking amps) is the max current that specific battery can supply in short bursts. 600 CCA is pretty typical, but I've seen up to 900 in the batteries I ship.
Is it really 600 amps? That seems rather high. I do know that the one time I shocked myself on a car battery, it rocked my world much more than getting shocked by a 110v outlet.
It has been 20+ years since it happened, but I'm pretty sure I was standing in a little puddle, or my hands were wet (can't remember which), and my wrench just happened to bump the positive terminal and it was like "POW! Right in the brain!". Thankfully I didn't latch on or anything. It was instantaneous, and over in half a second, but it rocked my world for that half second or whatever it was.
Obviously, Mehdi is an electrical engineer. The "dumb guy making things explode" is a persona he puts up to teach people about the dangers and wonders of electricity.
Say you made this, but insulated... does a car battery have enough structural strength in the terminals, though? I imagine you're left holding a handle with two terminals and half a cell stuck to each.
Yeah, they'd be fine. It's surprisingly difficult to break them apart. The load would spread out to almost the full width of the battery on either end (ie the plates attached to the terminals against the underside of the lid).
Some of the models I ship use plastic straps that hook onto the seam between the lid and base and you can really toss em around before they take damage. (some people are less than gentle with parts :/ but I'm not the manager so 🤷)
Some of the larger batteries with screw terminals might not survive, but the ones where these clamp style are used would be fine.
Imagine being so unbelievably shit at marketing, so brain-dead unoriginal and dense, so downright stupid, that you thought spamming the comments in Lemmy was a good marketing move
You can really see the spark of creativity with this idea
Certainly won't have any resisrance
I'm pretty amped about it!
Great Scott! This meme has summoned the Super Dads!
Well it does have potential
What happens next will SHOCK you
shocking dicovery
And quite current
Hot!
this one truly does spark joy...
Is there a just rolled into the shop on Lemmy yet?
I think the handle's a little short
The maker is probably not aware of the current battery sizes
He might be schocked by a batteries potential
While making such devices, one should be grounded to reality to avoid making such mistakes
We don't know. There is no banana for scale.
Banana plugs for scale
The three types of circuit:
Quick hand warmer.
And warmer!

Reminds me of this.
It's a suicide cord. Works great for generators
In short, this is a battery handle.
It will unleash the battery's potential
Might be terminal though
Perhaps, but I think we’ll see a high level of resistance.
That might be a hot take.
Would be pretty shocking if true
Are you positive? It's a negative over here
Correct, horse!
Battery staple.
Yes yes fun fun. In real life, I have some pretty huge batteries and there is a handle on each but the handle is a non-conductive rope.
Just remember to cut it when you dispose the battery, so that sea turtles won't get stuck in it.
Perfectly. Legal. Thrill.
Considering that a 12V battery has an internal resistance of 20 milliohms, the potential current through this thing would be approximately 600A.
It might be too hot to handle (pun intended)

V = IR Assuming 12.6V 12.6 = I* 0.02 I = 630
So yeah, it could hit 600A, if only until it got hot enough to melt something or change the chemistry
Well that explains why it hurt so much.

My guess is you were burned more than shocked.
Wait you can get shocked on a car battery??? I thought 12V was too low for you to feel.
Hmm. Giving it away a bit here. He cringes well before it discharges.

That's... immensely cool. I wish him luck in his dangerous endeavors.
Does he have a youtube channel or sth
ElectroBoom, 6 million subs if I'm not mistaken
ohhhhhhh I've heard that name, but I've never watched him.
I should.
Oh he new it was gonna be spicy
It was the last thing they made
With that hand, anyway.
Ooo a budget space heater
I was going to say, automatic heating on the handle. Nice features!

I work in an auto parts warehouse:

... It's conducive
Ah, I missed the root comment
And a face full of acid, I imagine
You just gotta use long screws to firmly connect it to the battery, or else it slips off.
Took me a min to realize...
I am a "ask me anything" Tech, ask me anything!
How long can you hold the handle once it's attached to a fully loaded battery?
For the rest of your life
Not really. You're not gonna get a shock, you'll just get very severe burns.
electroBOOM ⚡
Why does it smell like BBQ in here?
If it's plastic, then it's fine.
A bit of copper would spice things up
It can melt plastic does that count?
Plastic isn't a conductor, so the current wouldn't travel between the posts across the handle.
Metal is a conductor and would get very hot in a dead short melting plastic.
Yes but it wouldn't short because the current from one terminal would not travel across the plastic handle to the other
I was making a joke using the metal handle and melting plastic, instead of using the plastic as the handle.
better if it’s rubber
that's a killer gadget!
Users are calling it a shockingly good invention.
👀
For anyone wondering beyond the meme, they make these clamp handles that hold batteries pretty well for moving them around.

It's a bot, it doesn't care how many insults you throw at it. Just report and move on.
I think the insult was directed at the owner of the bot
Lmao it's not even the official website. It's fan-made? I didn't know Subway had fans, let alone fans that dedicated
