The Right Way to Store Batteries to Prevent Leaks and Damage

How to Store Batteries Properly to Avoid Damage and Leaks

Batteries are found in every part of your house, whether they are for smart devices, kids’ toys, TV remote controls, or flashlights. However, they may corrode, leak, or even pose a safety risk if not stored correctly. Small habits, like storing batteries properly, are the foundation of smart product care, according to Testergate.

Here’s how to maintain the longevity, safety, and readiness of your batteries for when you need them most.

1. Store Batteries in a Dry, Cool Location
The worst things for a battery are heat and moisture. Batteries should always be kept in a dry, well-ventilated area at room temperature, which is approximately 15–20°C (59–68°F). Steer clear of places like:

Restrooms (too wet)
Kitchens (which are hot places)
Window sills or direct sunlight

If your devices are not being used for extended periods of time:

Testergate Tip:
To avoid coming into contact with metal objects, use a storage case or drawer organizer.

2. Do Not Combine New and Old Batteries
Leakage or uneven drainage may result from combining new and old batteries in a device. Replace all of a device’s batteries at once, ideally using the same kind and brand.

Why It’s Important:

Avoids chemical imbalance
Guarantees a steady power output
Lowers the chance of device damage

3. Avoid Touching or Storing Batteries in Large Quantities
A short circuit can occur when loose batteries rub against one another or come into contact with metal. Always:

Keep batteries in their original container.
Use a plastic battery storage box instead.
Do not keep in metal containers.

Batteries should never be thrown in drawers containing coins, keys, or other electronics.

4. Keep Flammable Materials Away from Batteries
Inappropriate storage or damage can cause even household batteries to overheat. Don’t let them near:

Combustible materials
Cardboard or paper
Heat-generating equipment

Testergate Safety Tip:
Batteries should always be kept out of children’s and pets’ reach.

5. Verify Expiration Dates and Dispose of Outdated Batteries
When used properly, batteries deteriorate over time, even when not in use. Constantly:

Prior to storage, verify the expiration dates.
Rotate your stock, starting with the older ones.
Dead batteries should be recycled at a suitable facility.

Batteries should never be disposed of with ordinary garbage. The environment can be harmed by chemical leaks.

Extra Advice from Testergate:

For convenience, mark storage containers with the battery type (AA, AAA, 9V, etc.).
Remove batteries from devices that aren’t used often to avoid unexpected leaks.
Don’t refrigerate—that’s an old myth. In fact, storing batteries in the refrigerator can make moisture hazards worse.
