Battery storage question : LUSENET : TimeBomb 2000 (Y2000) : One Thread

I heard once upon a time that keeping batteries (AA, C, D and the like) in the refigerator was best for shelf life. Was that an old wives tale? If so what is the best storage method for keeping batteries. Thanks folks.

I store piles of AA for use in flash equipment. The refrig. system has served me well over the last 15y. Perhaps, there is a better way. We will have to wait and see what the answers give u

Ramp, Buy some rechargeable batteries and a solar charger. Available (still) in lots of places.

The idea of rechargeable batteries and a solar charger is good, but make sure what the voltage/drain requirement is for your equipment. Most of the rechargeable batteries don't match requirements for a lot of equipme

Storage in a refrigerator slows down the chemical processes in the battery that limit its shelf life, thus extending the shelflife somewhat. Conversely, storage in a warm location, such as next to a heater, or in a place that receives direct sunlight, heats the battery, and makes the chemical process proceed a little faster. The battery "runs down" faster than it would if it were stored in a cooler place.

All batteries, alkaline or rechargable, should be stored in a cool, dry place. Rechargables should not be overcharged.

If you follow these two simple rules, you will get the most out of your batteries.

Good Luck.

Also they should be put in ziploc bags. I understand they can be put in freezer for even greater life.

I keep my batteries in the refrig. However, Consumer Reports is about 3 or 4 years into a test comparing batteries stored at room temp w/those stored in the refrig. So far, no difference. Does anyone have an update on that test?
