You can really see the spark of creativity with this idea
shocking dicovery
And quite current
Hot!
this one truly does spark joy...

I think the handle's a little short
The maker is probably not aware of the current battery sizes
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.

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.

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.

Just remember to cut it when you dispose the battery, so that sea turtles won't get stuck in it.
Perfectly. Legal. Thrill.
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.

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?

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
