how to remove corroded batteries from a flashlight

The batteries give the flashlight the energy to light up your surrounding.s The battery cells contain ionic energy in them.

And by placing it into the flashlight, the flashlight creates a light when the bulb brightens up.

But removing the battery cells becomes difficult when those batteries get swollen up or get stuck in the flashlight.

Most flashlights do not have large access to the batteries. This means the condition of the batteries are out of your line of sight and regular supervision.

But getting the batteries out of the flashlight is important when they are corroded.

That is why we are discussing the steps to take the corroded batteries out of your flashlight. See the below section to learn more about it.

How to Remove Corroded Batteries from a Flashlight – Step by Step Process

You can easily remove the batteries from a flashlight with the help of vinegar and baking soda solution.

This will neutralize the corrosion and help the cells slide out more easily.

Step 1: Remove the headpiece of the flashlight

The acid liquid of the batteries can harm your skin. So, it is better to handle it with care. Wear gloves and work goggles for this process and protect the area that you’re working in.

In the beginning, you need to remove the headpiece or cap of the flashlight. You can remove the different parts of the torch to get the headpiece out of it.

The parts may change depending on the brand of flashlight or torch you are using. But most flashlights have a cap for the batteries that is screwed on one end.

Step 2: Fill the battery holder with vinegar and baking soda solution

The vinegar and the baking soda combo should be made into a thick paste.

This can also help you remove the acidic form of the battery in the battery holder from the torch or the flashlight.

Fill 1 tablespoon of baking soda and a tablespoon full of vinegar in the battery holder. This will help you reduce the acidic formation created by the batteries’ swelling.

Step 3: Cover the end with a tin foil

Now you need to cover the open end of the battery holder with tin foil. The tin foil will allow you to discharge the batteries that are swelled up inside.

Also, the foil will restrict the solution that could ruin other parts of the flashlight.

Step 4: Shake the battery holder

After you have covered the battery holder with tin foil, that will restrict the solution from coming outside.

Now, gently shake the battery holder for the solution to get distributed evenly.

The solution passing through will discharge the battery and will also help to remove the acid that got outside of the battery because of the swelling.

Step 5: Open the covering and let the materials come out

Lastly, you need to open the foil head and let the materials come out of the battery holder. Pour out the solution of the baking soda and vinegar.

Check if the batteries have come out or not. If not, then you might need to tap on the flashlight body to make the batteries come out.

You have to tap hard to bring those batteries out. Make sure that you do not touch the solution.

The solution may have a chemical discharge. So, it can harm your skin, or you can get yourself burnt.

After the batteries come out, clean the battery holder with a soft cloth and leave it to dry thoroughly.

Check for any corroded areas left with a small brush or even a toothpick for small crevices. Use a little bit of vinegar to neutralize the alkaline battery leakage.

If the battery was not extremely corroded, was cleaned out properly, and the terminals are still intact, you can use the battery holder again.

A reminder that the swelling up of the batteries discharges a lot of chemicals and acids. That interaction can be harmful to the skin.

So, keep these materials out of the children’s reach to keep them safe. But to be extra safe about batteries, read out the section below.

How to Get Corroded Batteries Out of a Remote

You can easily take the corroded batteries out of a remote using the same solution of baking soda and vinegar.

Get yourself the solution of baking soda and vinegar and use a cotton bud to apply it to the batteries of the remote.

Gently clean all sides of the corroded batteries to remove the acidic chemicals around them.

After you have removed all the chemicals, use gloves to remove the cells from the remote.

Discharge the batteries to the right place and clean the remote with the solution to remove all the leftover chemicals.

And leave it out for a while without using it and letting it dry properly.

How Do You Fix Battery Corrosion on a Toy

Using the same solution of baking soda and vinegar can help you clean all the types of battery corrosion in different things.

All you need to do is to use different tools to clean this up. To fix battery corrosion on a toy, you can use the help of baking soda and vinegar solution and a brush.

You can use the brush to clean the toy and the acidic discharge and to get the batteries out easily. This will help you fix the corrosion inside the toy.

Be sure to leave the toy out to dry thoroughly before attempting to replace the batteries.

Does Battery Corrosion Ruin Electronics

The battery corrosion can not ruin the electronics in the primary stage.

If the corrosion is new and you have cleaned it at an early stage, then it would not ruin the device.

But if the corrosion is kept for a long untouched period, then it might ruin the terminals of the power flow of the device. This can also ruin the device.

So, take care when using batteries. To prevent the batteries from corroding, be sure to use batteries that are not expired. That’s also why it’s better not to mix batteries. Replace each round with new batteries.

To prevent battery corrosion, keep batteries away from sources of high heat. As well, keep the battery terminals clean.

Finally, be sure that you do not give access to children to play with them because it could cause injuries.
