Fix a Corroded Torch

Fix a Corroded Torch

Every now and again, no matter how regularly you check your preps; sometimes we miss something. For example, you have a quick look at your torch, it looks fine, you put it back in your kit and wait until you need it. When the time comes, it doesn’t work! A quick battery change may be the answer. However, in this case when you open our torch up to change the batteries; you see that the batteries have leaked. You have a ruined torch!

The torch may not be dead just yet. You could try this method and see if you can bring your torch back to life.

What you need

Gloves – the battery acid that corroded the inside of your torch will do the same to your skin!
Eye protection
Dowel Rod
Hammer
Drill
Long drill bit
White vinegar
Bottle brush
Towel

What you need to do

Put on your gloves and eye protection.
Take your torch apart. Depending on the model – the top, bottom or both sections of the torch will be able to be unscrewed and removed.
Remove the battery

If the battery is stuck…

You will need to work a bit harder to remove it. If your torch comes apart at both ends then place a dowel rod against the top of the battery. Tap it gently with the hammer until it comes out.

If your torch only has one removable end then you will need to carefully drill into the battery until the drill bit is securely inside. Once this happens gently rock the drill bit back and forth and pull until the battery is removed.

Once the battery has been removed, you can start cleaning your torch.

Cleaning

Half fill the torch with white vinegar
Using the bottle brush, thoroughly scrub the inside of your torch to remove all acid left inside. There may also be little bits of battery inside if you had to drill it out so make sure these are brushed out too.
Pour out the vinegar and rinse the inside of your torch with clean water
Pour out the water and dry your torch as much as possible using the towel.
Allow the torch to air dry so the inside is completely dry before you use it again
Once it is dry, your torch will be clean and ready to be put back together again.

Considerations

Sometimes the acid corrosion will be tough to remove. If this is the case then you can allow the white vinegar to sit inside the torch for five minutes to help loosen it before using the brush to thoroughly clean.
If you do not feel comfortable drilling into a stuck battery then you can put Coca-Cola (or similar) or baking soda around the battery and this may help loosen it enough for you to remove it without drilling.
Make sure you wear your gloves and eye protection throughout the entire cleaning process. Battery acid can and will cause burn on your skin/eyes.
Dispose of the corroded battery appropriately. It is dangerous to leave it lying around as it can cause injury to pets, children and anyone else who comes into contact with it.

By regularly checking your torches and changing the batteries, you can prevent battery corrosion happening.
