Storing AA batteries so they don't leak?


About five years ago I came across Varta AA batteries and noticed the "10 YEARS POWER in storage". I thought it would be a good idea to buy a couple of packages and put them in a cupboard "just in case".

If they can last in storage for 10 years then I just buy them, put them on a shelf and don't have to think about them for a long time. Now five years later, I cleaned the cupboard and noticed the batteris in both packages had started to leak. One set says best before 12-2026 and the other 12-2027. It's now 01-2022 so they should be good for another 5 years or so. There is an asterisk after the "10 years power in storage" logo so I checked what it was about, but it was only that they should last at least that long, if not longer.

You are advised to take batteries out of devices if they are not used for some time, to store the batteries in dry and cool environments and so on. These were stored in the original, unopened package in a cupboard under very stable and good conditions, nowhere near any heat source of any kind or anything like that. What more can one do to prevent batteries from leaking?
