I think to a large extent, is just pure pot luck, I've had some old Every Ready D cells that have been installed for over 20 years and not leaked, likewise Duracell for around 10 years with no bother at all, YMMV.

Not luck. Two issues: Fakes and removal of mercury
Fakes issue is obvious
Hg was added to re-combine gases. Removed bcause it's toxic initial repalcemnts din't work well. Current ones OK
So very old batteries are OK genuine current ones OK. Fakes and ones from several years ago likely not OK.

I think it’s likely a combination of several things, as in years (ok, decades at this point) past, I rarely had a Corrodacell leak, but in the last 10-15 years or so see it alarmingly often.  I have a photo of some that began leaking in their retail package (bought from Home Depot, so not of sketchy provenance) while still several years shy of their 'best by' date.

I suspect it’s likely due to a combination of corporate bean counters and environmental regulations - the bean counters for 'value engineering' things to use the least possible amount of material in their construction, and the new regs for changing the chemistry and making it more corrosive.  The problem seems worse in the smaller cells (AA, AAA) than the bigger ones - maybe because so many are made they’ve been 'optimized' more (read that cheapened further), or being physically smaller sealing isn’t as robust and/or any internal pressure build up has less room to expand into so is inclined to squirt out sooner.

Here's an explanation:

--- Quote ---There are side reactions that generate hydrogen gas--basically the zinc breaks down the water. This gas will build up in pressure and eventually vent, driving some of the liquid electrolyte out with it. Manufacturers at one time uses mercury to form a non-reactive skin on the zinc to prevent this, but of course due to government mandates mercury is no longer used in alkaline batteries.

You can have my Brussels sprouts for all eternity if you're feeling short.  :-DD

mnem
now my broccoli... that's another story altogether. I'll fight you over that.  ;)

If I prepare the Brussel sprouts(insert a (relatively thin)slice of garlic in each cut open stem; add a hint of fresh ground black pepper; steam it just crunchy; salt), after the first you will fight me over the rest :-DD :-DD :-DD
/off to count how many ATMega128A-AU is hiding in those pieces of tapes

Cut them in halves, dip them in boiling water for 1 minute, then fry them in a generous amount of butter with equally generous amounts of salt and pepper, until there's some browning. Serve.

Almost.

You forgot to add the bacon lardons before the frying stage. Cook to completion, then pick out the Brussel's Sprouts, discard, and serve what's left.
