Place a set of rubber gloves on and some safety glassesĢ. This is potassium carbonate and forms when the potassium hydroxide reacts with carbon dioxide in the air.įor those who want to understand more about the chemical components inside an alkaline battery, please check out the followingġ. You may have also seen a feathery crystalline structure forming around the battery and terminal as well. Potassium hydroxide is a caustic agent and is the chemical that corrodes the terminals and destroys the batteries.
#DYSMANTLE BROKEN TERMINAL SKIN#
The potassium hydroxide inside the battery can irritate your skin (I know as I’ve touched it before!). I’m inherently optimistic (and also lazy) so I’ve never taken any of these precautions but it’s definitely good practice, especially with expensive electronic goods.ĭon’t use your fingers to try and remove the batteries. You can take precautions though to stop this happening such as not mixing different battery types in the same device, replacing all of the batteries at the same time, storing in a dry place and at room temperature, and removing batteries for storage of devices. The first is the most extreme corrosion where the terminals have to be replaced, the second is a small amount of oxidisation which only needed the potassium hydroxide to be neutralised and the terminals to be cleaned. This Instructable will go through a couple of ways that you can fix your device to bring it back to life again. if you don’t get to it in time however, then the corrosion can grow and spread out of the battery which causes oxidisation and corrosion of the terminals making your device caput. Eventually that pressure will find a way out through a seal or as the battery ages, through corrosion or rust in the outer shell.Īs soon as the first signs of a leak forms, then the best thing to do is to get rid of the battery. All batteries discharge, either through use or just slowly through the production of hydrogen gas which forms pressure in the battery. The corrosion is caused by potassium hydroxide which can leak out of alkaline batteries (these are the usual types of batteries you put inside toys etc). It’s usually one of the main reasons I think that people throw toys and whatever else takes batteries away. Many a time I’ve managed to get my hands on some electronic gizmo only to find that the battery compartment totally corroded.
