Yes, your freezer is not the Arctic. The cold slows the natural discharge.

I heard you put the bread in the freezer and the batteries in the refrigerator. My mom has put batteries in the Fridge for almost 30 years now. As for if it works I'm not sure but I can say I have never pulled a dead battery out of there! I have pulled some OLD batteries out!
Here we go I found a page that mentions it:
Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount. Hardly worth the effort of chilling them. However, if alkaline batteries are stored at higher temperatures they will start to lose capacity much quicker. At 85 degrees F they only lose about 5% per year, but at 100 degrees they lose 25% per year. So if you live in a very hot climate or are storing your batteries in a very hot location, it may be worthwhile for you to store your alkaline batteries in a refrigerator instead.
NiMH and NiCd batteries self discharge at a MUCH faster rate than alkaline batteries. In fact, at "room temperature" (about 70 degrees F) NiMH and NiCD batteries will self discharge a few percent PER DAY. Storing them at lower temperatures will slow their self discharge rate dramatically. NiMH batteries stored at freezing will retain over 90% of their charge for full month. So it might make sense to store them in a freezer. If you do, it's best to bring them back to room temperature before using them. Even if you don't freeze your NiMH batteries after charging them, you should store them in a cool place to minimize their self discharge.
(Note: Reviewing this information maybe I can understand why mom did that. In Nevada it can get 110 on a normal summer day so when you leave the house you turn the air so the house is probably 85 or so so I guess it did help in OUR case that she put them in the fridge.)

It depends on which type of batteries and at what temperature you normally store them.
Alkaline batteries stored at "room temperature" will retain 90% of their power for years without refrigeration. Under normal circumstances, refrigerating alkaline batteries will do little to extend their life.
NiMH and NiCd batteries, start to lose power when stored for only a few days at room temperature. But they will retain a 90% charge for several months if you keep them in the freezer after they are fully charged. If you do decide to store your charged NiMH cells in the freezer or refrigerator, make sure you keep them in a tightly sealed bag so they stay dry. Also, let them return to room temperature before using them.

Yes, it actually does. I had to do reasearch on that in college. If you put batteries in the freezer for a couple of hours to a day, it makes them last longer.

Put them in the fridge not the freezer

The moisture will make them decay faster

No, actually I believe the cold shortens their life.
