Need to Know Battery Stored in the Freezer

All over the internet you will find articles that recommend freezing batteries to extend their life. This is an old trick that people have been following for generations. It turns out that some battery freezers don't know the science behind it. We don't recommend this practice, and in this post we'll explain why. Now the Important Question is, Should batteries be stored in the freezer?

Before you get into the explanation, understand that it is very difficult to freeze a solid battery. A fully discharged battery can technically freeze up to 32 degrees Fahrenheit. On the other hand, a fully charged battery requires prolonged extreme cold to freeze. When people talk about "freezing" batteries, what they really mean is freezing them by placing them in the freezer.

First reason: Not necessary

 The oft-cited science behind the tendency of batteries to freeze is based on the concept of slowing self-discharge by lowering the temperature. In rechargeable lithium-ion batteries, lithium is one of the components that creates the chemical reaction needed to produce electricity. This electricity is generated by electrons moving from one side of the battery to the other.

Even when the battery is not directly powering the device, the electrons in it continue to move in slow motion. This is called self-discharge. Battery refrigeration enthusiasts believe that cooling the battery slows down this reaction. Technically, that's true. But in practice it doesn't matter.

The self-discharge rate of disposable alkaline batteries is already very slow. This can go on for years. Today's lithium-ion batteries are similarly slow. In some cases, they can self-discharge more slowly than alkaline batteries. Simply put, the extra life you get from keeping your Li-ion batteries cool is unlikely to be significant or even noticeable.

Reason #2: They need to warm up

Slowing down the internal chemical reaction in the battery reduces its performance. Cold batteries should therefore be allowed to warm up before use. Otherwise, you can actually shorten their life. Given the fast pace of life, do you really want to wait 30-60 minutes for the battery to warm up?

You should also clean the batteries before inserting them into the device. This is necessary for compaction. When heating frozen batteries, water droplets form on the outside. You can seriously damage this device if you don't scan them before inserting them into the device. If you leave the batteries in the device without heating or drying them, moisture can enter the device, which of course presents some risk.

Reason 3: Freezing Can Damage The Battery

Finally, we recommend that you do not freeze the batteries as this can damage them. Cold temperatures can cause the casing to crack. They can break up inside singles. What appears to be a very good strategy for extending battery life can actually shorten its life considerably. It doesn't make any sense.

After all, freezing batteries to extend their life is an old wives tale. It provides a nice folk and family life, but it does nothing for your battery. If you're really concerned about extending battery life as much as possible, it's best to stop using disposable alkaline batteries. Use rechargeable lithium-ion cells instead.

Pale Blue Earth USB rechargeable batteries can be recharged over 1000 times. A lithium-ion battery provides a much longer life than hundreds of alkaline batteries. Best of all, you don't have to worry about freezing your battery because of the ice cream.
