You can really see the spark of creativity with this idea
- Certainly won't have any resisrance
  
  Well it does have potential
- shocking dicovery
  
  And quite current
- 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
- We don't know. There is no banana for scale.
  
  Banana plugs for scale
  
  The three types of circuit:
  short circuit
  long circuit
  banana circuit

Quick hand warmer.
- And warmer!

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.
- 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
- 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)
- 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.
  
  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
  
  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.
  
  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.
  
  Oh he new it was gonna be spicy

Ooo a budget space heater
- I was going to say, automatic heating on the handle. Nice features!

It was the last thing they made
- With that hand, anyway.

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.
- I work in an auto parts warehouse:
  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.
  
  ... It's conducive
- 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

electroBOOM ⚡

Why does it smell like BBQ in here?

that's a killer gadget!

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.
- better if it’s rubber

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.

- Jokes are not allowed in the Memes community.
- I see a flaw in this design…
  You don't say?

- 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
  
  It's a bot, it doesn't care how many insults you throw at it. Just report and move on.
  
  Lmao it's not even the official website. It's fan-made? I didn't know Subway had fans, let alone fans that dedicated
- Who even needs an "ultimate guide" to basic ass Subway sandwiches? They aren't complicated.
