It can block the charge from the battery to the system if there is to much. The corrosion gets between the terminals and the power won't go through. If you have corrosion on your terminals you need to clean them.
Sulfuric acid fumes escaping from the battery.
Battery corrosion is toxic and very corrosive to metal. It might be in your best interest to call your physician and ask them what to do.
The deposits resulting from corrosion create an impediment to the flow of electricity.
Hydrogen gas escaping from the battery causes this corrosion.
A very thin smear of Copper Grease over the Battery terminal / Cable end will help pevent corrosion.
Controlled corrosion of the metal electrodes inside the battery.
Sulfuric acid fumes escaping from the battery causes this corrosion.
yes
possibly
It can remove corrosion from a battery cable.
They absorb the sulfuric acid fumes which causes corrosion.
If there is corrosion on the terminals then you will have a bad connection that will not transfer power from the battery to the starter. It is just like disconnecting the cable. Electrical current cannot flow properly through the corrosion,
