I'm not too keen in the acid H2SO4 pooring all over the driveway.
I know what happens when a truck / tractor battery or accu short out and it is not funny at all.
We had on a farm tractor, Samé Atlanta, two six volts series 21 plate 105 Ah batteries short out under the hood while trying to pull a stuck load with a big jank.
The batteries were not secured and one welded itself to the hood, and the top blew off, acid all over the tractor, luckily no one hurt, lot of damage and corrosion afterwards and a big hole melted in the hood.
These AA and D cells are being thrown out at work when flat so they give us a bit of fun and smoke at home on our driveway.
The caustic components are easily contained after the experiments. Some D cell battery tops of course will decay somewhere in our garden and flower beds :-)
The remains get put in a plastic bag and goes to the councils battery recycling place.
More clips will follow with Nicads and Lithium cells.
