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).
