I haven't noticed a difference as leakage for me seems more correlated to the brand rather than just the size. I think that the main problem with AAAs is that alkalines will become leak prone once the charge gets low and AAAs have low capacity to start with.
Interesting that alkalines are more prone to leakage when the charge gets low. I didn't know that. Thanks.
This is what I'm in the process of doing. I've got the AAs covered but am short on AAAs for now. I still stock alkalines in a small quantity usually I get them with new devices or buy used devices with alkalines that test out fine in them. I typically buy dollar store alkalines when I get low and need a few. The funny thing is of all my alkalines I've stocked in the last few years only the name brands have leaked in storage the cheap brands haven't leaked at all and cost 1/3 to 1/4 as much.I have quite a few devices that use either AA or AAA's and have not noticed a difference in the rate of failure using alkys. I have a stash of Alky's AA & AAA for a crisis, but they are my last. By switching to Energizer Lithiums & Eneloops I have not had a single leak. As a result, I will just build up my supply of these cells and no longer keep a stock of alkalines.
My experience is the opposite. Very few alkaline leaks that I remember but those that did were all AA. I use primaries in everything.
Well, they've got less capacity, so all other things being equal out makes sense that they'd become over depleted sooner than AA.
We'd also assume that they'd be put into less current thirsty devices than AA, like TV remotes, little liquid crystal clocks, etc. But there's plenty of miniature high drain devices, FRS radios, flashlights, and the like.
me too, my AAA remote controls and calculators always has leaky alkaline in them
