Putting batteries in the freezer or refrigerator doesn't necessarily prolong their life
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.

I havent tried putting batteries in the freezer but have put alkaline batteries in a warm oven for a short while to rejouvenate them.
YES,YOU CAN RECHARGE BATTIERS BY PLACING THEM IN A FREEZER! I PUT MY DAUGHTER'S AKALINE C" BATTIERS IN THE FREEZER FOR 24 HOURS ,WIPED THE ICE FROM THEM,AND PLACED THEM IN HER SWING ABOUT 45 MINUTES AGO AND THEY WORKED LIKE NEW BATTIERS! THEY WERE COMPLETLY DEAD AT FIRST! I HAVE BEEN RECHARGING BATTIERS IN THE FREEZER FOR YEARS AND I NORMALLY CAN DO THIS ABOUT 2 OR 3 TIMES BEFORE I HAVE TO BUY NEW ONES.DON'T KNOCK IT UNTIL YOU TRY IT BECAUSE IT WORKS!!! PEACE AND BLESSINGS TO YOU:)
I heard that years ago but I never tried it until now. It worked for me. I only tested aaa Dollar General and Polaroid brand batteries. These batteries where completely dead prior to the testing. I have an mp3 player and when the battery is new it shows three bars. I placed two batteries in the freezer together (dg and polaroid), then a couple of minutes later I placed another DG brand battery in the freezer. I tested the DG battery that was in the freezer the shortest time and it only gave me one bar. I later tested the Polaroid and the other Dgg battery that I put in together. The Polaroid batttery didn't give me any bars but the mp3 player still came on while the DG battery gave me all three bars. It worked the best for the DG brand. Maybe it only work for certain brands or types and you have to keep them in the freezer for a certain period of time. I don't know the exact amout of hours I kept them in there but it was over 10 but under 24. The DG that gave me all three bars was an Energy Super Plus battery and The Polaroid was a Super Alkaline. I'm not sure what the other DG battery was. Also, I don't know how often you can recharge but I don't plan on recharging more than once because I'm sure it would stop working eventually.
yes it does it can restore them for a cuople of hours example 24 it does not long and shut up loser yes it does don't listen to him try it waatch
