Introduction |
If you open your device and see white, crusty crystals on your battery terminals (a.k.a. battery contacts), they have’ve most likely corroded. Common replaceable batteries like AAs and AAAs degrade and start to break down over time, and a chemical reaction causes corrosion. Corrosion can stop the flow of electricity and damage your device’s metal contacts. Use this guide to remove corrosion and clean the battery terminals in your small electronic devices. | | ***Note:*** This guide is specifically for small electronic devices such as video game controllers, TV remotes, or portable speakers.
