Can You Recharge Alkaline Batteries-Freezer and Charger

Batteries make our lives very easy, especially the small ones as they allow us to carry our devices along with us without any worries. However, there used to be some batteries that were not that good in terms of specifications and efficiency.

However, with all of the improvements, newer batteries are made which can provide better performance and efficiency. These are the alkaline batteries and here is all you need to know about recharging these batteries?

Can you recharge alkaline batteries in the freezer?

Some batteries are known to charge better when exposed to cool temperatures. There are 2 major reasons behind this phenomenon with the batteries

Cooler temperatures lower the self-discharge rate

The energy loss due to heat is reduced which helps in faster charging.

However, when it comes to alkaline batteries things are a bit different. Instead of an enhanced charging process, the efficiency of the charging process decreases when you put these batteries in the freezer.

The Chemical Reaction Taking Place in the Alkaline Batteries

One major part of the charging process happening inside the batteries is played by the electrolyte of the battery. Some batteries come with a solid electrolyte that performs well when exposed to cool temperatures. The case is different with alkaline batteries.

The case is very different with these batteries as they come with a liquid electrolyte. So, whenever these batteries are exposed to the colder temperature the reaction process on the electrolyte changes which causes loss of efficiency in the charging process.

What is the best way to charge the alkaline batteries?

When you are looking to charge your alkaline batteries there is not a lot that you need to do. All you need is to make sure that the batteries are neither cold nor too hot. Batteries being at room temperature will be charged in the best manner.

So, if you are thinking that you can charge your alkaline batteries inside the freezer then you need to rethink as the working principles of these batteries are very different as compared to some other ones.

Alkaline Batteries in a NiMH Charger: Things You Need to Know

Yes, charging the alkaline batteries in the NiMH charger is possible. However, there are some checks that you need to take a look at before you start with the process. These things will ensure your best experience of charging the battery.

Things you need to consider when charging the alkaline batteries in a NiMH charger.

Before you start charging the alkaline batteries in the NiMH charger make sure to take a look at the following things.

Battery Type

The first thing you need to check is the battery type. Although the main name is an alkaline battery there are several types covered under it. However, mostly these types are divided into 2 main categories. The rechargeable ones and the non-rechargeable ones.

When you are looking to charge the alkaline batteries, you need to ensure that the ones you are going to charge are the rechargeable ones. Otherwise, there could be an issue that may result in something as bad as a fire.

Battery Specifications

Now that you are sure about the type of your battery you need to take a look at the battery specifications. The main thing to check here is the voltage of the battery as these batteries come in different voltage ranges.

Charger Specifications

Charging the battery using a NiMH charger does not only need checking the battery specifications as you need to check the charger specifications as well. The main thing you need to check here is the charging voltage as well because you will never want to charge your battery at the wrong voltage values.

Can you recharge 9-volt alkaline batteries?

There are a lot of things that take the 9-volt battery as their portable power source. When using these things one major concern is charging the batteries for better efficiency. So, most people ask if it is possible to charge the 9-volt alkaline batteries.

Same as above you will need to start with checking the battery if it is rechargeable or not. If the battery is non-rechargeable then charging it will create greater gases inside the batteries which can result in fire or explosion. However, charging the rechargeable alkaline batteries has no issues as long as you are using the right charger.

Why should you consider charging the 9-volt alkaline batteries?

There are several reasons why you must prefer rechargeable 9-volt alkaline batteries over non-rechargeable ones. Some of those reasons for selecting the rechargeable 9-volt batteries are mentioned below:

These batteries have a higher energy density that makes them last longer as compared to some other batteries with the same specifications

These batteries do not cause a major issue in the environment as compared to the alternatives when disposed of

These batteries can last for years

Alkaline batteries have a higher resistance to temperature. So, they perform well as compared to some other batteries.

Why should you not consider charging the 9-volt alkaline batteries?

Some reasons will tell you not to go for the rechargeable 9-volt alkaline batteries and some of those reasons are:

The fault in the charger can cause the battery top to go bad or even explode

These batteries can be damaged by devices and can result in leakage

These batteries have a high internal resistance that leads to reduced output.

So, when it comes to charging the alkaline batteries, you can do things easily but there are pros and cons to it like everything else.

Conclusion

Alkaline batteries make great alternatives to some other non-rechargeable and even rechargeable batteries with their amazing specifications and performance efficiency. However, along with all of this efficiency you need to be a little careful about things like the charging process.

As long as you do things in the right way there will be no major issues and you can enjoy using these batteries as per your requirements. We hope that now you know all about the best way of charging alkaline batteries and the things that you need to care for.
