How to Store Dry Cell Batteries
A dry cell battery uses a paste to suspend the electrolyte. The paste has enough moisture to allow current to flow. It therefore does not require as much care in handling as a wet cell to prevent acid spills. Flashlight batteries and batteries for electronics are examples of dry cell batteries. By contrast, car batteries usually use wet cells, with a water-based electrolyte.

1
Take small batteries out of sensitive electronic equipment--if more than two weeks will pass in between use--to prevent an acid leak from causing costly damage.

2
Store 1.5 to 9 volt batteries in a plastic bag, in a refrigerator. The plastic prevents the batteries from discharging against metal objects. Don't put more than two batteries in one bag, to avoid discharging through terminal contact.

Allow cold-stored batteries to warm to room temperature before installing them. Though rare, cold batteries placed under a load can explode.

4
Store batteries for disposal or recycling in 5-gallon plastic pails or 55-gallon metal trash cans with a plastic liner. Store the battery upright, if possible, to prevent an acid spill. Do not pile other debris on top. Note that many stores that sell batteries also take them back to be recycled.

5
Do not store dry cell batteries on metal surfaces. Do not let them get wet or overheated. Do not allow a direct connection between the positive (+) and negative (-) terminals of the batteries.
