How to Charge a Dry Cell Battery

How to Charge a Dry Cell Battery? Try Out This 2 Simple Methods

Charging dry cell batteries can be really time consuming task. Some of them take ages to charge and some don’t even charge at all!

But now your frustration has reached the boiling point. That’s why you’re here!

You want to know how to charge a dry cell battery?

To charge your dry cell batteries, first, take your regular charger or CVC battery charger. Then, insert the plug into the wall mount and make sure the connection is stable. After that, place the batteries in the charger carefully. Finally, turn off the power when it’s done recharging.

Well, that’s only the cutdown version. It might not be enough for you to actually go through the whole process. That’s why you’ll get a step-by-step if you keep reading.

Can I Really Charge My Dry Cell Batteries?

A dry cell battery is a marvelous invention and it’s great to use. However, people have vague ideas about what a dry cell battery actually is.

A dry cell battery uses an electrolytic paste to produce electrical energy. So, the name dry cell comes from the dry paste used in the chemical process. 

There are many kinds of dry cell batteries. Some are used in remote controls, RC cars. Others are widely available for cars, industrial machinery, and so on. 

Dry cell batteries are durable. Not only that, but dry cell battery lifespan can end up ranging from 8-12 years.

While the majority of the dry cell batteries are non-rechargeable, some can be recharged.

So, you might question:

Can dry battery be recharged?

The answer to that is yes, they are rechargeable. For example, nickel-metal-based batteries are rechargeable. You can charge these types of batteries with a constant 1.2 voltage of input.

Now that your confusion is cleared, you’ll understand the next segments without breaking a sweat! 

Dry Cell vs Wet Cell Batteries: The Differences

After going through the last segment, you might think you understand a lot about batteries. But do you really think you understand all about the rc batteries? Wait till you read about these two very different batteries.

As discussed before, dry cells use the gluey electrolytic paste to convert chemical energy to electricity. 

Although the paste is almost solid, the current flow without any trouble. These types of batteries are quite eco-friendly and come with many automobiles and RCs. They come in different forms such as c2, c4, and so on.

The other type of battery that you might hear about is wet batteries. As the name suggests, they use two electrodes (cathode & anode) and liquid electrolytes to produce electricity. The common electrolyte that is used in such batteries is sulfuric acid.

That’s why they are also known as lead-acid batteries. These batteries are less environment-friendly and also available for cars and similar machinery.

To make the comparison easier, here’s a table for you:

Battery Life6-48 months8-12 Years

As you can see, these batteries have very contrasting characteristics. While the maintenance cost of dry cells is low, the price is high. 

On the other hand, you need to regularly maintain the voltage and acid level in wet cells. As a result, you get to purchase them at a comparatively cheap price.

So, both of these batteries have some strong and weak points. That’s why I try to consider all the factors before making the next purchase decision.

What Do I Need for Charging Dry Cell Batteries?

Do you feel you’re ready enough to start the recharging? I must say that there’s still something left to do. Because you need some equipment before you can start the dry battery charging process.

So, what will you need for recharging? First of all, you’ll obviously need a dry cell battery charger. I mean, how are you supposed to charge the batteries without a freaking charger! You can look at these chargers which I can safely recommend-

These are our top picks, and boy, did they perform well! You should definitely try these out for charging your batteries!

Next, you’ll need a voltmeter to check the voltage change. Without that, you won’t know if the dry cell battery is charging or not charging. Also, it can help you to check if your NiMH battery charge holding or not.

Lastly, you need to choose a stable wall bracket to plug your charger. Always remember to read the charging manuals for your safety. 


One extra thing to mention. If you want to charge your batteries via an industrial plus-sized battery, you’ll need cables. Which cables? Those clip cables with plus and minus heads.

That’s about it for the initial preparation. Now, you are ready to charge your batteries!

Dry Cell Charging Procedure

Now that you’re ready with all the essentials, it’s time to dive in. Here’s your charging process with full details:

Step 1: Finding the Right Charger

First, pick the charger according to your batteries. There are many types of dry cell chargers out there.

Step 2: Plugging In 

Insert the charger plug into a wall charging port. Check if there’s any problem with the charger before plugging in.

Step 3: Charging the Batteries

Put the batteries in the charger according to the plus and minus sides. Turn on the power.

Step 4: Finishing Off

Lastly, check with your voltmeter if the battery is actually charging. If so, leave the charging on until it’s finished.

So, get recharging your RC batteries right away!

How to Charge a 12V Dry Cell Battery?

Charging your 12V dry cell batteries is a bit more tricky than others. It’s a very different process compared to charging your 2/3 aa batteries. But don’t worry, here is the simplified and the right process-

Step 1: Checking Voltage

12V batteries need proper checking of the actual voltage before you charge them. Try to maintain C/10 current rate for optimal output.

Step 2: Inserting the Charger

You can use a dry cell battery trickle charger or taper charger for this step. They are quite inexpensive and easy to find. After picking them up, plug the charger into the wall mount.

Step 3: Constant Monitoring

Again, try not to exceed 14.7V while charging. Otherwise, your dry battery life will have a negative effect. After the charge reaches 13V, turn off the charger and you’re done!


That’s the proper way to charge your 12V dry cell batteries. You can now try it all by yourself!


What are the Optimal Settings to Charge My Batteries?

The settings vary depending on your battery size. If you want to charge a 10 Ah dry cell battery, then it’s best to use a 1 Amp dry cell charger. However, when you have a 5 Ah battery, the optimal charger output should be 0.5 Amp. The recharging process can take roughly about ten-twelve hours.

Is it Possible to Revive Dead Dry Cell Batteries?

The typical NiCad dry cells batteries can be easily revived by recharging them. First, you’ll need to completely discharge the batteries and check manually if they are dead. Then, place the batteries into your charger and give them a full charge. Now, you have brand-new dry cell batteries! 

Is LiPo Battery Same as Dry Cell Battery?

Fundamentally, LiPo batteries don’t use any liquid electrolyte as a base. It uses dry paste as the main substance for transferring the current flow. Lithium Polymer batteries are made with the same formula that is used in dry cells. So, yes, LiPo falls in the same category as dry cells.


I believe that’s everything I had on how to charge a dry cell battery. You can now easily charge and recharge your batteries as much as you want.

So, don’t worry about discharging your batteries completely, and enjoy!

Thats all.Goodbye!
