How can battery corrosion be prevented?

Here’s how to prevent battery corrosion:

Perform routine maintenance. From time to time, look for signs of corrosion on the battery. When you change the oil, you should do this. By checking your battery regularly, you’ll be able to catch any early signs of corrosion and fix it before it gets worse.

Use a protective treatment. Commercial sprays or brush treatments to prevent corrosion can be purchased at auto parts stores. Before using the battery cables, disconnect them to interpose them between the cable and the terminal.

Make sure your battery is properly charged. Corrosion can result from overcharging or undercharging the battery. Take your battery to a mechanic if it frequently overcharges or undercharges. They can find out why.

Use Vaseline or battery grease. Corrosion can be prevented by coating the terminals with battery grease or Vaseline. Before applying either, remove the battery cables. Because it’s silicone based, battery grease will last longer on a hot engine.
