The batteries help the flashlight to get the energy to light up the surrounding. The batterie cells contain the ionic energy in it.

And by plugging in it to the flashlight, the flashlight creates a light, or the bulb lightens up.

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

Mostly the flashlights do not give available access to the batteries. This makes the batteries stay out of regular supervision.

But getting the batteries out of the flashlight gets very important.

That is why we are discussing the steps to bring the corroded batteries out of the 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 to bring out easily.

Step 1: Remove the headpiece of the flashlight

At the very beginning, you need to remove the headpiece of the flashlight. You can remove the different parts of the torch to get the headpiece out of it.

The parts variation may change on the brand of the torch you are using. But most of the torch is made in a singular pattern to follow.

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

The vinegar and the baking soda solution is a miraculous solution that can help you to do many things.

This can also help you to remove the acidic form of the battery in the battery holder of 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 to 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 a tin foil. The tin foil will allow you to discharge the charge of the batteries swelled up inside.

Also, the foil will restrict the solution to ruin any 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 to come outside.

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

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

The acid liquid can harm the skin. So, it is better to handle it with care.

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 get in touch with the solution.

The solution may have chemical discharge in it. 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. And you can again use the battery holder for your torch to light up.

The swelling up of the batteries discharges a lot of chemicals and acids. That interaction can be very harmful.

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

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 the very beginning, then it would not ruin the device.

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

So, be careful while using batteries as a way of getting power supply. Make sure that you do not give access to the children to play with it.

That can cause severe accidents for your child.
