Mistakes, splashed droplets, unexpected trickles, leaky containers, unventilated fumes -- these can damage work sufaces, clothing, skin, eyes, and lungs. It's not ALL that hard to do safely, but the required level of care may be more than you want to volunteer for in your routine gardening activities.
That said, I don't see anything in this idea that would disqualify it from working with a weaker acid that's safer to handle. Say, white vinegar (acetic acid, usually 5%).
You'll need more of it, and it will need more time to work. Warmth will help. Perhaps put the batteries in a pop bottle of vinegar, store in sunny place, shake from time to time?
Likewise your chelating agent. If conditions of your life make collecting and saving urine inconvenient, I should thing a bit of cleaning ammonia (the cheap stuff, no added soaps or perfumes, just dilute ammonia) would work.
Disclaimer: I haven't done this. I am musing about possibilities. Be careful out there. Don't make any accidental soda-pop-bottle bombs.

It sounds as if John was describing carbon-zinc batteries, not alkaline, right?
This would work the same for either, right?
