Battery Corrosion Car Wont Start

It’s a scenario we’ve seen far too often at Field Automotive. You’re running late, you make a dash for your car, turn the key with anticipation, and… silence. Before despair sets in and you begin contemplating the inconvenience of alternative transportation, let’s consider a lesser-known but significant adversary: battery corrosion. Though numerous issues can prevent a car from starting, corrosion on battery terminals is a critical but often overlooked factor that can immobilize your vehicle.

Delving Deep into Battery Corrosion

Battery corrosion typically appears as a white, blue, or greenish powder around the terminals. This isn’t merely a cosmetic problem; it’s indicative of a chemical reaction happening either within the battery or between the terminals and the air. The most frequent type of corrosion occurs on the negative battery terminal, caused by the hydrogen gas released by the battery acid reacting with the surrounding atmosphere.

This corrosive substance effectively acts as an insulator, disrupting the electrical current flow from the battery to the car’s electrical system. In its mild form, it can lead to weakened electrical connections, dimming lights, or sluggish starts. Neglected, it can severely escalate, completely preventing your car from starting.

The Culprits Behind Battery Corrosion

Battery corrosion, while common, doesn’t arise without reason. At Field Automotive, we’ve identified several factors that contribute to its formation:

  • Overcharging: An overcharged battery emits excessive hydrogen gas, hastening the corrosion process on the terminals.
  • Aging Battery: Older batteries tend to leak acid or gas more, leading to corrosion.
  • Environmental Factors: Corrosion accelerates in high temperatures and humidity. Coastal areas can also exacerbate battery corrosion due to salty air.
  • Electrolyte Leakage: Damaged battery cases or improperly sealed caps can result in electrolyte leakage and subsequent corrosion.

Understanding these factors is essential in preventing battery corrosion and ensuing issues.

Combating Battery Corrosion: A Step-by-Step Guide

Initial Inspection

Start with a visual inspection of the battery. Look for signs of corrosion, leakage, or damage to the terminals and cables. Corrosion is often the primary suspect when a car refuses to start.

Effective Cleaning

Eliminating the corrosion is crucial for restoring the battery connection. Remember to disconnect the battery cables, starting with the negative terminal, to avoid short circuits. A solution of baking soda and water can neutralize acid, and a wire brush can remove corrosion residues. Once the terminals and cables are clean, rinse with water and dry thoroughly.

Preventative Measures

Post-cleaning, apply a thin coat of petroleum jelly or specialized battery terminal protectant. This layer acts as a barrier against the corrosive elements.

Battery Testing and Possible Replacement

If the car remains non-responsive, further tests with a multimeter can check the battery’s condition. An output below 12.6 volts indicates either a failing battery or another electrical issue.

Enlisting Professional Assistance

Should these steps not yield results or if corrosion recurs frequently, it may signal deeper electrical problems requiring expert intervention. At this stage, seeking professional help is advisable.

Field Automotive’s Pro Tips for a Corrosion-Free Battery

“A little attention goes a long way in maintaining a healthy battery,” says Field Automotive. Here are some insider tips:

  • Regularly inspect your battery for signs of damage or corrosion.
  • Ensure the battery is properly mounted and secure to minimize vibrations.
  • Monitor your battery’s charge level, especially during extreme weather, to avoid overcharging or deep discharge.
  • Retain a schedule for battery maintenance, cleaning, and application of protective terminal coatings.

Maintaining a Regiment for Battery Care

Regular battery maintenance is less about severe measures and more about consistent observation and action:

Check Frequency Action
Monthly Visual inspection for corrosion and terminal tightness
Bi-annually Battery voltage check and cleaning
Annually Professional battery and electrical system inspection

Implementing these practices can significantly extend the life of your battery and enhance the reliability of your vehicle.
