The Best Way To Store Batteries: Tips For Optimal Performance And Longevity

While recently visiting a friend, I opened her refrigerator to grab a Coke and was surprised to see a neatly organized container of batteries in the door. When I inquired about the storage solution, she simply replied, “That’s what you’re supposed to do!” Who knew?! To be transparent, I grew up with a smattering of batteries of all shapes and sizes tossed into the elusive junk drawer, and that habit has stayed with me well into adulthood. Is putting batteries in the fridge necessary, and can you damage batteries by storing them together? To find the answers to our burning battery questions, I turned to Energizer, the St. Louis-based company with everyone’s favorite bunny mascot. 

How Should I Store Batteries For Long Periods Of Time? 

Serial organizers, this answer is for you. If you’ve been bitten by The Home Edit bug and decant everything into nice, neat storage solutions, you can carry on. The key to battery storage is simply to keep them in a cool, dry place at room temperature. That means drawer storage works just fine, and Energizer says there’s no need to go the extra mile to put them in the refrigerator. The urban house myth likely came from a time when batteries weren’t as efficient. You should, however, be especially mindful of storing batters in hot places. Avoid those Southern attics and garages. 

Can I Store Different Types Of Batteries Together?

The short and sweet answer is no. Mixing various types of batteries, or old and new batteries, can contribute to leaking or rupturing, which could ultimately cause personal injury or property damage. It’s best to keep like with like. Another tip from Energizer is to replace all batteries at once. As tempting as it might be to get that remote to operate a little longer by just replacing one battery, it’s not a good idea. 

How Can I Safely Dispose Of Old Batteries?

It’s completely safe to toss dead everyday household batteries into the garbage as you would any other waste. However, Energizer recommends recycling them instead. Call2Recycle is a nationwide resource for finding a drop-off recycling location near you. 

How Do I Clean A Leaking Battery?

Battery leakage, another term for battery acid, can be harmful if it touches your skin or seeps into products or soil. It’s also what causes corrosion. If you find that a typical, alkaline battery has leaked, start by wearing gloves before handling it. Next, put it in a plastic bag before adding it to your garbage; this will keep the leaking residue contained. Clean the device or container using a mild acid such as white vinegar or lemon juice. This process will cause a little fizz and when that stops, you can wipe the area dry. 

Are There Any Specific Storage Requirements For Rechargeable Batteries?

Rechargeable batteries have a similar set of rules and recommendations. Be sure that you recharge your batteries according to their specific directions and be mindful to not overcharge, which can cause overheating. To prevent overheating, most batteries and chargers are built with safety features. Extend your rechargeable’s life by charging them at least every six to nine months. Only recharge batteries labeled "rechargeable." Charging a non-rechargeable battery can cause it to leak or explode. 

Other tips and tricks for rechargeable batteries are: 

• Avoid extreme temperatures by storing them in a closet or drawer away from direct sunlight. 
• To preserve battery life, store them at 40-50% charge.
• Keep batteries individually wrapped or in separate compartments to prevent short circuits.
• Store batteries away from metal objects to prevent damage.

What Should I Know About Lithium Batteries? 

A lithium battery is a type of rechargeable battery that uses lithium ions to store energy. Think smartphones, laptops, and tablets. Since these batteries are different than traditional alkaline, they have their own unique set of care instructions: 

• Always use the charger specifically designed for your device. 
• Inspect your batteries for any signs of swelling, leakage, or damage. 
• Avoid full discharges. Deep discharges were once recommended, but modern lithium batteries benefit from being kept at a moderate charge level.  

Perhaps the most important factor to remember about lithium batteries is that they can be dangerous for air travel. In checked luggage, batteries are subjected to various pressures and temperatures, increasing the risk of damage, so it’s best to keep these batteries with you in the main cabin.
