![]() 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.
