Battery Corrosion is a common phenomenon and it can be found 75% of the time under the hood of automobiles, in boats, golf carts, and solar system. It is because the sulfuric acid used in batteries produces hydrogen gas, which is the primary factor behind the corrosion process that naturally occurs on your battery cables. When your vehicle and battery are operating, very small amounts of gas are released through the vent cap. When released, these fumes naturally combine with the heat, dirt and humidity in the air, plus other active agents under your hood, like grease, oil and coolant, to form corrosion on your battery cables and terminals.
Battery corrosion can be a real trouble to get rid of once it starts if not fixed quickly. If you choose to ignore the corrosion problem, it will lead to other problems down the road. It will eventually interfere with the connection between the battery and cables attached to the battery. Common problems due to corrosion are automobile starter dragging, charging problems related to your battery, and no starting ability. In golf carts, not being able to charge all batteries evenly, cables becoming hot and melting during charging, and of course short run times due to state of charge of the batteries. Boat batteries attract corrosion, because of the high humidity and sometime salts that are present in their environments.
How to Remove Battery Corrosion
To remove battery corrosion, first you need to locate the battery posts that are corroded. Before you do it, please be sure to wear gloves to protect the hands from any acid that may be built up on the posts.- Pour cola on individual battery post and let set for 15 seconds. You will see the cola bubble up. This is the cola eating away the corrosion and is normal.
- Wipe off excess cola from individual battery post with shop rag. Repeat on second battery post.
Once you have all of the corrosion gone, and the battery and connectors are dry. You then must coat the battery posts with the terminal spray or lithium grease. Put your terminals back on red positive first, then black negative. Tighten your cable connections, and the job is complete. Always remember to wear safety goggles and rubber gloves when working with batteries.
How to Preventing Battery Corrosion
Preventing corrosion is simple and easy to do. Here are some simple steps for your to follow.
- Find a clean wire brush used for car cleaning and repair. Grab a regular tub of Vaseline from your medicine cabinet.
- Conduct regular battery service on your car battery. Make sure your car battery is working properly and isn't in need of major repairs. If your car battery needs to be changed, replace it with a new one.
- Locate the terminals on the car battery.
- Disassemble the terminals.
- Use a wire brush to painstakingly clean them. Clean each crevice and side so that no corrosion accumulation remains.
- Reassemble the car terminals with car battery.
- Coat the terminals generously with Vaseline so that all parts of the terminals are protected against corrosion.
- Clean your hands with soap and water. Pat dry.
- Turn on your car after awhile to verify that your car functions as it should.
