Why do I have corrosion on the top of my battery?

Corrosion on top of your battery could be caused from a bad connection, but most of the time the battery itself is leaking through the seal around the post. If you have it cleaned and the corrosion comes back then it's time to replace your battery. 



We can do a battery check for you, battery acid needs to be handled carefully and fumes can lead to an explosion.
