When you connect a car battery to a copper wire you can cause corrosion in the battery terminals. Generally if the corrosion is occurring on the negative terminal your system is probably undercharging. Electrolytes from the battery can then build up on the terminals and cause corrosion to form.
If the electrolyte leaks out and accumulates around the battery terminals due to lack of proper maintenance or damage then therell be corrosion.
Battery corrosion prevention pads available at Walmart and auto parts stores will slow or stop the corrosion process.
