Keeping Primary Batteries in the Freezer


1. Why you should freeze batteries

Making them last longer couldn't be easier!
Making them last longer couldn’t be easier!

Batteries don’t come cheap, and it’s both frustrating and costly when they run out.

Keep your toys, remotes and other battery-powered items going for longer by storing your batteries…in the freezer.

That’s right!

Most people don’t know, but batteries begin to discharge (even when not in use) at room temperature. Storing batteries in the freezer can reduce their loss of power by up to 90%, so it’s definitely worth doing.


Cold storage issues

This was coupled with the fact that a battery will drain faster if you take it straight out of a cold environment and start using it. In the case of zinc-carbon, all those self-discharge savings are quickly lost if the battery is used straight from the chiller!

On top of this, many people experienced batteries which rusted faster and then leaked due to the condensation caused by cooling and/or warming of the batteries too quickly. This was also caused by using them straight away where the heat the battery generated caused the condensation.

This all then lead to the general advice that fridge or freezer storage of batteries was a bad idea and there was nothing to be gained from it.

Manufacturer contradictions

Contradictory advice now abounds, even from the most respectable of sources.

A clear example is Energizer. Their Non-rechargeable batteries: Frequently Asked Questions document specifically states that “storage in a refrigerator or freezer is not required or recommended for batteries produced today” but their Carbon-Zinc application manual provides data proving that their own range of carbon based batteries benefit from reduced self discharge and states “The storage of carbon zinc batteries at temperatures below 21°C will increase their service maintenance” before going on to demonstrate that “storage at 5 to 10°C is effective“.

You would be forgiven for thinking that if a company like Energizer has mixed messages … who really knows?

8. Freezer hack for bakers

Are you a fan of baking?

If, like us, you have a bit of a problem with portion control, freezing your dough for later could help.

When you bake, make a batch of dough, then bake only the cookies you intend to eat that day. Portion the others up, and freeze for later.

These can then be pulled out of the freezer and baked when you fancy a cheeky mid-week treat.

Does Putting Dead Phone Batteries In The Freezer Revive The Batteries?

Dead batteries should not be placed in the trash right away. There are ways to revive a dead battery. You can still restore the cells in two different ways or method. Find which one will suit you best.

Method 1: Freezing the batteries

1. Remove the battery from the phone. 2. Place the battery in a sealed plastic before placing it inside a plastic container. Avoid using paper bags or foils because water can easily sip in. 3. Place the sealed battery inside your freezer. Leave it on your freezer overnight or at least 12 straight hours. 4. Remove the battery from the freezer. Let it warm down to room temperature. Avoid using the battery while it is frozen. 5. Remove moisture from the battery. 6. Return the array in your gadget but don’t turn it on yet. Charge your phone using its charger. Allow the battery at least 48 hours of charging time. 7. After loading your phone for at least 48 hours, you have to check the battery power level. You will notice that it can hold its charge again.

Method 2: Jumpstarting the batteries

1. Ready everything you will need in jumpstarting your cells. For this, you will need a : ● 9V battery ● Electrical tape ● Electrical wire (You may choose the red and black wire). 2. Connect the positive and negative terminal of your phone battery to the electrical wires. You can quickly determine these through the + and – signs. Phone terminals usually have more than one battery terminals. Better use the ones that are far from each other. Never used the central terminals. 3. Use electrical tape to cover the connections. Be careful with the contacts so as not to interchange it. 4. Connect the wire of the positive terminal to the positive terminal of your phone. Do the same thing with the negative end. 5. Secure the connections by using electrical tape. Store it at cold temperature and away from water and heat. 6. Let it sit for about a minute or until the battery gets a little warmer. Make sure to monitor the charging time and be on the lookout every time. 7. Disconnect when you feel that the battery is already warm to touch. 8. Place back the battery in your phone and check if it powers on. 9. See the battery level when you put it on. When the charge is not yet done, put it back and wait until the battery becomes fully charged.

Characteristics Of Rechargeable Batteries

Though rechargeable batteries are somewhat different from one another, they have these similar characteristics. I am carefully observing the characteristics will perhaps tell us how to maintain them accurately.

1. Cycle life of these batteries depends on the amount of maintenance received. Failure to apply full periodic discharge on this battery may affect its cycle life at least three times. 2. Depth of release can also change the cycle life. Shallow discharges can save battery life than deep discharges. 3. Internal protection circuits can consume at least 3% of the battery’s stored energy. 4. Rechargeable cells are capable of high current pulses. 5. Maintenance of these batteries can be done through topping or equalizing charge. 6. The cost of the battery is divided by the battery cycle, and it does not include the electricity cost and chargers. 7. The temperature range for these battery types are more confined, and it applies only to discharge. 8. Battery discharge is highest after charging; then it begins to taper off.

Of all the rechargeable batteries that I have mentioned, only NiCd has the shortest charging time, but it delivers the highest current voltage. However, NiCd demands a very high maintenance value.

It is indeed tough to determine the correct charging procedure and care for these rechargeable batteries for our gadgets and devices. It is commonly used by almost everyone who owns a gadget and mobile phone.

Asking questions that concerns the charging capabilities of our batteries is but ordinary. Can you recharge batteries in the freezer? It is a simple question that raises a lot of inquiry about the rechargeable batteries we are using.
