how best to store aa, aaa, d cell etc batteries?

Fridge not freezer. Nextr time buy rechargeables and you wont have to worry about storage.

I've known people that keep their batteries in the fridge - I have no idea either way if it works or not. I figure just in a drawer where it's not close to heat or cold. Nothing drastic, just room temperature.

In a room temprature atmosphere, away from sunlight, in non-metallic containers.

so....pretty much in your kitchen drawer.

The freezer thing doesn't work by the way.
