How To Store Batteries in a Bug Out Bag

I do not know about you, but batteries are one of those items I tend to forget about after purchasing. 

How To Store Batteries In A Bug Out Bag

Once I have them or place them into a device, I expect them to work forever.

Sadly, like many things, that is not the case. 

Considering the number of gadgets we use these days, we are quite dependent on batteries. Knowing how to safely store them in a bug out bag will allow us to be better prepared and keep our tools ready to go.

How Long Do Batteries Last?

Alkaline batteries which are still some of the most common batteries used have a shelf life of between five to ten years. 

But several things can be done to extend the life of our batteries.

What to Keep in Mind 


Batteries and moisture do not go well together. When batteries are stored in humid conditions, corrosion can develop, which takes away from its ability to properly function.

This is why batteries should be protected against humidity as best as possible.  


Temperature extremes in either direction can damage a battery. 

After reading numerous forums and manufacturer’s websites storing batteries in the refrigerator or freezer is not a good idea. There is quite a bit of moisture in both environments and as stated above, that is not good for a battery.


Due to temperature extremes or being physically unprotected, batteries can begin to leak or become ruptured. 

In both cases, it is best to not use batteries in this condition.

Because of this, batteries will need some form of physical protection. 


When storing batteries, they should be stored with common ends aligned. 

This means all of the positive terminals should be pointed in one direction and all of the negative ends should be pointed in the opposite direction. 

This helps to avoid a short circuit and leakage from occurring. 


When a device is not being used the batteries should be removed. 

I know, this is a pain and throws a wrench into always being prepared, but batteries stored in a device will shorten their life span even when the device is not being used.

So when thinking about the above recommendations one of the best ways to store batteries in a bug out bag is in their original packaging. 

This packaging provides a good barrier against moisture and keeps batteries properly oriented. 

But this packaging can be somewhat flimsy in terms of physical protection. 

There are hard battery containers available that are both watertight and offer better physical protection from a battery becoming punctured. 

If you have numerous loose batteries that you want to organize, considering properly orienting the positive and negative ends and holding them together with rubber bands. This bundle can then be placed into hard watertight containers or a simple resealable plastic bag. 

Batteries in a bug-out bag that is stored in a vehicle are not going to fare so well in regions that experience temperature extremes. As much of a pain as it is, it is best to keep a bug out bag in an area that is consistently cool. 

Wrap Up

Batteries are the lifeblood that help us to power flashlights and various other gadgets that can be essential during emergencies.

Only by properly taking care of them can we hope to rely on them in our time of need.  What are some of the ways you store batteries in your bug out bag? Sound off in the comment section below and let us know. Thanks for reading and stay prepared!
