Your Jiffy Lube®
Maybe one evening you notice your vehicle’s headlights are a little dim. Or perhaps your vehicle is suddenly slow to crank. You pop the hood, and there it is: chalky white flakes, or green or blue material on the battery terminals. It’s corrosion, and it happens over time because of the battery’s chemical structure.
Don’t panic. It’s a common problem that’s not hard to fix. But don’t ignore it, either! Because of the essential role the battery plays in your vehicle’s starting and charging system, it needs to continuously operate at an optimal level. As car battery corrosion builds up, it can interfere with battery performance. So, let’s learn about car battery corrosion so you can remove it safely.
Think back to Science 101, when you learned that dissimilar metals in the presence of acid could produce an electrical charge. Generally, a car battery’s posts, cable connections, and cables consists of three different metals:
Off gassing of hydrogen normally occurs during battery charge and discharge. Contained within this off gassed hydrogen is a minute amount of acid from within the battery. That acid mixes with debris and moisture in the air under the hood and corrosion naturally occurs.
We’ve explained why car battery corrosion is bad. Now let’s cover how to remove it. Before you attempt to do it yourself, remember safety first!
When it comes to how to clean a car battery, there are two popular methods: store bought chemical cleaners or the greener, homemade method.
Of course, you can always bring your vehicle to Jiffy Lube®. There are many drivers who, when asked “How to clean a car battery?” will respond, “I let Jiffy Lube do it!” That’s completely understandable. Not everyone has the time, or the inclination, to scrub away under the hood. Jiffy Lube technicians are trained to perform battery maintenance service.
Jiffy Lube technicians will be thorough and take these steps to detect and prevent battery damage to help preserve the life of your battery:
The results of this battery checkup will be presented to you. And, as always, the technicians welcome your questions. One of Jiffy Lube’s goals is to help drivers make educated decisions about their vehicles and service.
The trained technicians at Jiffy Lube use quality products including Pennzoil® products (where available) and will consistently install parts that meet or exceed Original Equipment Manufacturer (OEM) recommendations.
