That’s why you connect it directly to main so it doesn’t require a closed loop to create a chemical reaction,.
Comment on So how would you handle this?
expatriado@lemmy.world 17 hours agothe path of least resistance for the current would be down one connected bolt, then around the top plate, and up the other battery connected bolt, never down the pole, so the ceiling/floor gets heated up, possibly burn
note: those bolts must be supper long to go from ceiling to floor

12v is hardly anything. This is not a joke, go put your hands on both terminals of a car battery. You won’t feel a thing.

12 V is not enough to pass through unbroken skin, yes. But 12V has plenty to pass through some bolts and heat up enough to burn your house down.
You may be interested in StyroPyro’s video where he wired 100 car batteries in parallel. Still 12V, but huge current capacity.

still can spin a big truck and/or turn on incandescent bulbs with temperatures in the thousands of degrees
the internal resistance of lead-acid batteries is in the tens of mili-Ω, the circuit of 2 bolts and one plate/top of the pole would be in the low 100s mili-Ω. lets round up to 200mΩ, power = V•I = V^2•R = 12^2/0.2 = 720W, enough to heat up the top assembly of the pole, and smolder some wood

That’s true but only because the voltage is low a car battery can pull ~2X the amps in of main it won’t kill you because it can’t connect but if it ever did
