The Battery Fridge-Safety and Storage

Mar 01, 2021   Pageview:50

Most batteries have a lifespan of four years, and those well maintained can last longer than that. Many have had to ask if storing their batteries in fridges will help them in keeping their batteries longer. The answer is yes. However, most manufacturers do not recommend such storage. The reason for this is that they believe that the moisture from the fridge could damage your battery in different ways.

They recommend the use of a sealed- airtight plastic bag to store your battery in the refrigerator because this way, the moisture in the fridge will not damage your battery. For people whose houses or garages are warmer than room temperature then, the battery fridge method is their means of storage for their batteries. Batteries tend to lose charge easily when they are not stored in a cool place.

Is it safe to keep batteries in the fridge?

There are two answers to this question, and that is it is safe to keep batteries in the fridge and other times it's just a bad idea. To begin with, batteries are recommended by manufacturers to be stored in cool places because low temperatures decrease the rate at which energy is discharged from their batteries. A cameraman, for example, can charge his or her camera batteries and store them in the fridge and get them later to go and use; this storing helps his or her batteries to retain a charge.

The reason why keeping batteries in the fridge is a bad idea is because too low temperatures damage the lifespan of a battery. The batteries, in one way or the other, experience self-discharge, and storing them in the refrigerator cannot prevent that, and rather it can just slow the rate of self-discharge.

Most of the battery manufacturers recommend batteries to be stored at a dry, clean room temperature. The fridge has an extremely cold temperature which could damage the battery long term. Most of the rechargeable batteries such as Nickle—metal hydride lose charge easily, and for that, keeping those in the fridge prevented such losses. Improved rechargeable batteries have been manufactured, making them safer to store at room temperature instead of in freezers or fridges.

It is not safe to keep your batteries in the fridge because there is too much humidity there, and that is a serious problem for your batteries as they are supposed to be kept in a dry place for a purpose. For the people who must keep their batteries in the fridge because of a particular reason, then it's advisable to use an airtight container that cannot allow any water vapor into your batteries.

Note that fridges are only recommended if the temperature is extremely hot and there is no way the temperatures are changing soon.

What is the best way to store batteries?

Batteries are stored to offer a long and better service, especially those that one has acquired and has not used yet. It is fundamental to ensure that you store your batteries right for you to use them when need be.

Note that as much as you want to store your batteries, they all have different life spans, and that shows that some may just die due to time. There are basically four steps to storing your batteries in the best way possible, and these are discussed below.

The first thing you need to do is to separate your batteries from any equipment they are in. This makes sure that when you store the batteries, no charge is being used at all as compared to when it's in any equipment. If your batteries leak or corrode, your equipment will be safe because you have removed the battery first before storing it.

Secondly, look for a dry, dark, and cool place to store your battery. Remember, as much as freezers and fridges may be an option of storage, and your battery has more to lose than gain. For example, storing your battery in a fridge may experience condensation, which damages it and thus reducing the lifespan of your battery.

The third step that will ensure that your batteries are stored well is to ensure they are contained before storage. Contained storage ensures there is no vapor coming into contact with your battery. It is advisable to use the original packaging of the battery for containment, and if that is not enough, one may get a battery storage box that is widely available. These boxes should be vapor proof, and that will prevent batteries from going bad because of the moisture.

Lastly, ensure all you're your batteries are separated from each other and the positive terminals are facing the same direction. Make sure you store your new and old batteries separately to avoid damages that may be caused by leakages.

Can batteries be stored in the cold?

Batteries can be stored in the cold and, in this case, the freezer or fridges. Storing your batteries in these two reduces the temperatures of the battery and prevents them from losing their charge. Always remember that this is not the best way, but it can be used if there is no otherwise. If need be, always ensure your batteries are inside of an airtight sealed plastic bag to prevent moisture and humidity.

The best temperature to store your batteries is 15 degrees Celsius. It is fundamental, therefore, to ensure your cold storage is not extremely colder than 15 degrees because that will damage your battery. The lower the temperatures, the higher the humidity, and that is dangerous for batteries.

If the cold place you want to store your batteries is below 15 degrees, Celsius it's not wise to use that place for your battery's safety measures. Simply the best place to store your batteries is in a dry place with cool temperatures that do not exceed 15 degrees or are below that by a big margin.


It is imperative to note that batteries can be stored in fridges, but that is not the best method of storage. We have seen that if it's a must to store your batteries in a fridge, especially in extremely hot conditions, then the use of airtight plastic bags is essential.
