How to Remove Corroded Flashlight Batteries

If you have a flashlight that has, for some reason, fallen into water and left to sit, you may have found the batteries have corroded and leaked into the inside of the flashlight. If this happens, it is not necessary to throw the flashlight away. Instead you can safely remove the corroded flashlight batteries and clean out the inside, allowing you to use the flashlight again.

Things You'll Need

• Flashlight
• Drill
• Drill bit
• Vinegar
• Toothbrush/bottle brush
• Water
• Rag

Instructions

1. Unscrew the top of the flashlight, exposing the corroded batteries. You may want to wear cleaning gloves while doing this so the material does not rub off onto your hands.

2. Turn the flashlight upside down over a trash can and hit the backside of the device. This may be all that it takes to remove the batteries.

3. Install a long drill bit into a drill if the batteries did not come out. Power it on and drill into the battery.

4. Pull back on the drill (with it powered down). The batteries should come right out with the drill bit.

5. Pour a small amount of vinegar into the bottom of the flashlight once the batteries have been removed. Scrub the inside with either a bottle brush or a toothbrush.

6. Pour out the vinegar and rinse thoroughly with water. Dry out the flashlight with a rag and set it aside to dry completely before placing new batteries into the device.
