Watch Out For Battery Corrosion This Summer

Posted July 14, 2020

As temperatures have risen in Littleton, we’ve seen more and more customers coming in with a failing battery. One common culprit: Corrosion.

Corrosion on your car battery can reflect normal wear and tear on your vehicle as the battery ages, but it can become worse with high temperatures in the summer months. While it can be okay to see a small amount of corrosion at the terminal, large buildups can signal a problem.

Causes of Battery Corrosion
Most often, corrosion occurs on the battery terminals. The sulfuric compound inside car batteries emits hydrogen gas, which can be trapped under the hood and corrode the terminals.

Small leaks or loose connections to lead to corrosion. If you notice a crack in the unit or acid leaking on the outside, you might have a serious problem. When you notice this, bring your vehicle in to our shop right away for an inspection and to replace the battery.

Symptoms and Warning Signs
As corrosion occurs, you’ll start to see white, green, or blue material building up on the terminals. Small amounts may be harmless, but if the build-up continues to grow it can interfere with moving the charge from the battery to the engine.

The electric charge inside the unit needs to be transferred to the engine in order to run your vehicle. If enough corrosion has built up on the terminals, less current will travel through the terminals. You’ll notice a loss of power and may even require a jump start to get going.

Problems with Corrosion
The most common effect of a corroded car battery is not being able to start the vehicle. But even if you’re willing to put up with frequent jump starts, latent problems can manifest due to related problems. Accessories like the radio or cabin lights may fail without enough power.

If the problem persists, your vehicle’s on-board computer may show issues or fail to operate. The on-board computer receives important information from the many sensors in your vehicle to keep it running, alert to potential issues, and keep you safe. Ignoring issues may put you at risk.

What should you do?

If you notice corrosion, bring your vehicle into our shop – our ASE-certified technicians will remove the corrosion and thoroughly inspect the battery and all other related components.

Corrosion could be a sign of a more serious problem. Don’t ignore the warning – schedule an appointment or drop in anytime to have your battery tested and inspected to have problems identified early to avoid hassle and expensive repairs down the road!
