Do Batteries Last Longer if Refrigerated?

 Do Batteries Last Longer if Refrigerated?

There are many websites that claim that storing batteries in a refrigerator or freezer will improve their performance. We wanted to take a deeper look into this as it is something a family member used to do and I never really understood why, or if it helped at all.

So the general belief is that by keeping batteries in the refrigerator you can help them to not lose their charge nearly as rapidly, thereby making them last longer. I want to first say that if this is something that you do, it probably isn’t a very good idea. It does not prolong their life, and the condensation when you take the batteries out can actually cause them damage.

The image above is a screenshot I have just taken directly from the Duracell FAQ page in which they clearly state “Extreme heat or cold reduces battery performance,” and, “refrigeration is not necessary or recommended.”

Here is what Energizer have to say:

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.

Here is what Eveready have to say in their FAQs:

Storing batteries in refrigerators or freezers is not required or recommended for batteries produced today. In fact, cold temperature storage can harm batteries. To maximize performance and shelf life, store batteries at normal room temperatures with moderate humidity levels. – Eveready

So there you have three of the leading brands of batteries all agreeing on the same thing, that it is not recommended to store your batteries in the refrigerator.

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).

So, in a nutshell, don’t refrigerate batteries.

Battery Do’s and Dont’s

Follow the tips below on the best way to store, handle and care for your batteries, whether at home or on the road.


  • Keep batteries, especially small and coin lithium batteries and the devices that use them, out of the reach of children.
  • If you suspect that your child has swallowed a coin lithium battery, take them to the emergency room immediately and tell the doctors; the suspected battery and identification number from the packaging. Do not give them a drink until an X-ray has been done.
  • Always read the instructions on your device before installing batteries and only use the size and type of battery specified in the instructions.
  • Insert the batteries properly. Follow the symbols showing the correct way to position the positive (+) and negative (-) ends of the batteries.
  • Keep battery contact surfaces clean by gently rubbing with a clean pencil eraser or cloth.
  • Immediately remove drained batteries from the device and dispose of properly.
  • When changing batteries, remove all batteries from the device at the same time and replace them with new batteries of the same size and type.
  • Preserve battery life by switching off a device and removing the batteries when it’s not being used, and is not expected to be used for extended periods of time.
  • Keep your batteries in a cool, dry place at normal room temperature. It’s not necessary to store batteries in a refrigerator.


  • Dispose of batteries in a fire — they may leak or rupture.
  • Disassemble, crush, puncture, or otherwise damage batteries. This can result in leakage or rupture.
  • Carry loose batteries in a pocket or purse with metal objects like coins, paper clips, etc. This can short-circuit the battery, leading to high heat or leakage.
  • Recharge a battery unless it is specifically marked “rechargeable.” Attempting to recharge a non-rechargeable (primary) battery could result in leakage or rupture. Don’t use rechargeable alkaline batteries in nickel metal hydride battery chargers.
  • Store batteries or battery-powered devices in hot places — elevated temperatures can lead to capacity loss, leakage or rupture.
  • Mix old and new batteries, or mix different types or makes of batteries. This can cause leakage or rupture, resulting in personal injury or property damage.
  • Give batteries to young children.
