We searched on "batteries freezer" and also looked at several battery manufacturer's web sites to find the answer to this question. The search results led to a very detailed frequently asked questions (FAQ) page about AA and AAA cell batteries, as well as its related battery myths page that provided a plethora of information about batteries. According to these sources, storing batteries in the freezer (or refrigerator) will make them last longer, but it depends on what kind of battery you're using. And in the long run, it may not be worth the hassle. For alkaline batteries (the most common kind of household battery), putting them in the freezer will extend their shelf life by less than 5%. And cold batteries can't be used immediately -- you have to wait until they've warmed up to room temperature first. If you need those batteries for a flashlight in an emergency, this could prove problematic. When stored at room temperature, alkaline batteries retain 90% of their power, and the average shelf life of alkaline batteries is five to seven years. For NiMH and Nicad batteries (often used for electronics), storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. Battery manufacturers tend to agree. Kodak says "refrigeration is not necessary, nor is it recommended" and "freezing is not recommended" for its alkaline batteries. Duracell advises: "Do not refrigerate Duracell batteries. This will not make them last longer." Both recommend storing batteries in a cool, dry place.
The old school freezer trick will not work but for a small time to restore dying or dead batteries. It is best to replace the batteries.
I dont know the answer
Placing batteries in the freezer will likely damage them.
No....batteries do not regain power by placing them in the freezer. The only good that comes by storing batteries in the freezer is that the lifespan of the battery is increased but only by a very small percentage. (less than 2% longer lifespan)
2/12volts batteries
There are none - freezer burn is delicious.
No, putting cassette tapes in the freezer will not revitalize them. This will damage the tapes. However, putting batteries into the freezer will revitalize the battery charge.

They must be keep at room temperature, it's a bad idea to put the into a freezer.
Yes, it is safe to freeze certain types of batteries, such as alkaline batteries, but it may not necessarily improve their performance. However, lithium-ion batteries should not be frozen as it can damage them and affect their functionality.
what may be causing my freezer to work but my refrigerator not to work
To my understanding, on end of the freezer blows air, quite rapidly, towards the other end which acts like a "vacuum". This is called an "air curtain" and acts just as a door would, keeping cold in and heat out.
