Among the many problems ailing AAA batteries today, leaking is among some of the most common and frustrating. Leaks occur when a battery has been left in an electronic device too long. Unfortunately, the only way to know this is to find the mess of battery acid in the battery pack of the device.

Although battery acid is known to be a toxic liquid, cleaning an area that has had a battery leak. Take proper precautions for a safe clean-up.

Also, make sure you are not wearing anything that the acid can ruin. An old t-shirt is fine, or even a smock that you can throw away if need be will work.

Throw Them Out

The first thing you need to do in a leaky battery situation is to throw the broken batteries out. Alkaline batteries are especially dangerous to handle, so wear gloves and possibly goggles. Place them in a Ziploc bag and dispose of them away from pets or curious children.


Ventilate the area well so that fresh air comes in to circulates around the battery acid. A small amount of acid will probably not harm anyone in your home, but try to work in an open garage, a picnic table or a large open room.

Make a Mixture

A mixture of lemon juice and vinegar will clean out battery acid. You should not use water as it can be dangerous when mixed with the acid.

Clean Out the Acid

Dab a cotton ball in the mixture and clean out the acid from the battery compartment. You can gently swab it out, exchanging dirtied cotton balls for newly dabbed ones in the process.

You can use the toothbrush for this process as well. Simply dab the toothbrush in the mixture and scrub out the area well. Use a cotton swab to clean up any extra material.

Using the baking soda and your toothbrush, scrub out the area well to make sure there is no left over residue from the battery or the mixture. This also helps sanitize the area for future use.
