Should we store our batteries in the refrigerator or freezer when we leave for the summer?

I've heard mixed responses to this question so did some research.

Snopes interviewed both Duracell and Energizer on the subject:

Says Duracell about this belief: 

Should I store my batteries in the refrigerator or freezer?

We recommend storing batteries at room temperature in a dry environment. Extreme heat or cold reduces battery performance. You'll want to avoid putting battery-powered devices in very warm places. In addition, refrigeration is not necessary or recommended.

1. Is it a good idea to store batteries in a refrigerator or freezer?

No, storage in a refrigerator or freezer is not required or recommended for batteries produced today. Cold temperature storage can in fact harm batteries if condensation results in corroded contacts or label or seal damage due to extreme temperature storage. To maximize performance and shelf life, store batteries at normal room temperatures (68°F to 78°F or 20°C to 25°C) with moderated humidity levels (35 to 65% RH).

Mythbusters did a whole show about this subject and found that the batteries that lasted the longest were those stored at room temperature.  The batteries stored in the refrigerator had the poorest performance.  Here's a link to the show if you care to watch:
