I've seen people put their batteries in the refrigerator before.....is that supposed to make them last longer or something?

No, not with modern batteries. The idea behind cooling something is that chemical reactions slow, and thus the self-discharge problem is minimized. The old lead-acid cells benefitted from this, alkaline and lithium do not.

I agree.
I tried the batteries in the freezer, but I couldn't tell any difference.

I've gone over to Nickel-Metal Hydride rechargeable batteries, and I'm just tickled pink with the results.

They don't run down in a month sitting waiting to be used like the Nickel Cadmium rechargeable batteries used to.

Solved all my battery storage problems! I just keep a few extra charged ones laying around, and when the old ones come out, I put the fresh ones in the device, and throw the discharged ones in the charger!
Works great!
