Actually I had some old batteries leak. The safest way to store old electronics is in a dry room at room temperature and without batteries. Batteries should be stored in small metal containers each in a big metal box near a window (in case of a explosion/fire - smoke is the biggest danger).

A good. That's how we currently store them separately 👍

If you are interested, that's the calculator I actually lost due to leaking batteries. Sadly the acid has corroded the circuit board, it's a total loss. www.manualslib.com/manual/12399...
