hmm, $2,580.00 now we're getting more affordable. Still with one chamber or a couple that figured multiplies up. How about checking manufacturer specs on their batteries, and choose just a few temp/humidity settings? Time, well ten years is absurd for any of us to do. There is the idea of accelerated tests.
killer here is: time, your time, cost, and space. for me it would become an obsession
The batteries that leaked, did you buy them from Woolworths?
Seriously, follow up:
how about adding a Silica Gel Desiccant Canister?

into those bins? and caulk seal them? and wait 10 years?
Maybe by a mini fridge to keep at 68f (20c) degrees or 60f degrees, (not too cold, not too hot)?
OK, more like just an idea. I have a mini frig used separately for photo film and paper, (yes, I still print using a darkroom) while food frig remains below 40f degrees, I seal or double seal the photo stuff at about 62f degrees and freeze the long-term film.
I already have a small manual thermal chamber. The key is to temprature cycle and humidity cycle. Preferably you'd have seperate temperature and humidity chambers so you can do two different types of tests at once.
Not expensive to get a decent temperature chamber, but one that adds programmable humidy adds to the cost a lot.
Plug it into a lamp timer that turns it on for a set period of time each day. If you want something fancy, buy or build a proper temperature controller with a programmable profile, I'm sure there must already be an arduino program to do this floating around somewhere. Raspberry pi with a temperature sensor, SSR and a python script would do it too.
... switch to NiMH?
https://en.wikipedia.org/wiki/Nickel–metal_hydride_batterynot a solution. 1.2 volt just doesn't cut it. I have a tv remote that will not work with nimh.
and I don't really want to muck with rechargeable all the time.
I think I'm going to have to get a proper temperatue and humidity chamber...
It's a slow process.
If your "normal use" means changing the batteries every few weeks then any leakage during that time will be so small that you won't see it without careful inspection.
My theory is that all alkaline batteries start leaking the second they come off the conveyor belt. Some just take much longer than others to make a mess.

Why can the (alkaline) battery industry not make a battery that does not leak ? Are they that incompetent ? or is there something else going on ?
Nothing else you own can switch over because you have one remote that can't?
Why would it be any more "mucking" than Alkalines?
Perhaps the things that is going on is… reality?
QuoteWhy would it be any more "mucking" than Alkalines?i can walk into any store and buy one-time use cells. not so with rechargeables.
if the charger goes out : stuck.

50 years, and they have not been able to design a proper seal ?
So I would say the seal works perfectly as intended: it releases potassium hydroxide. What improvement could be done to it?
One of the big advantages advertised for alkaline cells over carbon-zinc cells when they initially became available was not leaking.
Entire technology rejected because it's easier in the deep, dark corners of your laziness to keep throwing landfill-to-be at a problem.
If the charger goes bad, go buy your landfill and use it for a short while until you get a new charger.
How often does that happen compared to not having any spare alkaline batteries in the house?
PS: You're allowed to own two chargers.

and they have been spreading that lie ever since...
It'd be a pretty poor cork seal if it lets the wine out of the bottle..
euh. like , not release potassium hydroxide or anything else ? Isn't that what a seal does : keep stuff inside the containment vessel?
euh. like , not release potassium hydroxide or anything else ? Isn't that what a seal does : keep stuff inside the containment vessel?I believe that, at this point, it’s clear that explaining how an alkaline battery works is necessary. I avoided that so far, as chemistry is not my thing, but it seems unavoidable now.
Alkaline battery operation is described on Wikipedia and I will just sum it up. Zinc reacts with manganese dioxide, with potassium hydroxide acting as the electrolyte. Potassium hydroxide is dissolved in water, forming K+ and OH- ions, and the negative ions participate in the reaction. Theoretically the reaction is perfectly balanced.
Reality is, however, not perfect. Reactions do not happen instantenously, molecules are not everywhere in perfect proportions all the time and the entire process does not happen in a vacuum away from any other substance. We have positive potassium ions dissolved in water. Potassium loves reacting with water and that’s a very violent relationship. While in an alkaline battery the raction is not as impressive as what you get by throwing alkali metals into water, but it still happens — slowly, over time. And the reaction is: 2K+ + 2H2O → 2KOH + H2. Do you see the second product? That is hydrogen, which slowly accumulates in the battery, increasing pressure.
If you have a perfectly sealed container and pressure rises inside that container, do you know what happens? Kaboom. Do you want kaboom that spreads a strong base, a mild neurotoxin, and a gas, which mixed with oxygen in air will happily explode on any source of ignition? I believe not. That would deal much more damage not only your devices, but also you. So alkaline batteries have a seal at the bottom, which is expected to let pressure out safely. The battery still spills its guts, but only just a bit and in relatively peaceful manner.
The problem is not the seal. The problem is chemistry of alkaline batteries. It’s a problem inherent to their operation.
