Understanding Battery Corrosion
Battery corrosion is a chemical reaction that occurs when the battery’s electrolyte (a mixture of sulfuric acid and water) comes into contact with metals like lead and lead dioxide, which are found in car batteries. This reaction produces a white, powdery substance (lead sulfate) that can build up on the battery terminals and posts.
Several factors can contribute to battery corrosion, including:
- Extreme temperatures: Both heat and cold can accelerate the corrosion process.
- Loose battery terminals: Loose connections can allow moisture to seep in and promote corrosion.
- Overcharging or undercharging: These conditions can lead to excessive electrolyte buildup and increased corrosion.
- Old age: Batteries naturally deteriorate over time, making them more susceptible to corrosion.
