I have a small collection of dolls, mint-in-box. One of them is a singing doll, press her belly and she sings (fifteen-second recording). I've had her since late 2013/early 2014. I checked her box, it says she uses three AG13 batteries.

What is the shelf life of AG13 batteries? Do AG13 batteries corrode? If they don't corrode, I'm fine with leaving them in her. If they do corrode, I have to take the doll out of her box so that she won't be ruined. In doing so, she is no longer mint-in-box.

I rarely press her belly so her batties should be good in that regard. I tested her last night and she still sings. Does anyone have knowledge about these batteries?
