Why Do Battery Terminals Get Corroded?
Corrosion on battery terminals is a common issue that can lead to significant problems if not addressed. But why does it happen in the first place? Let’s dive into the causes of battery terminal corrosion.
the causes of battery terminal corrosion
Battery terminal corrosion primarily occurs due to a chemical reaction involving the battery acid and the metal of the terminals. When your battery operates, it releases hydrogen gas. This gas, when it comes into contact with the air, moisture, and salt around it, triggers a chemical reaction that results in corrosion.
Another contributing factor is the leakage of battery acid. Batteries are sealed with a bushing to prevent hydrogen gas from escaping. However, if this bushing fails, hydrogen gas can escape directly at the terminal, causing corrosion.
Moreover, the volatile chemicals or gases inside a battery can escape and come into contact with the terminals, leading to corrosion. This is particularly common in lead-acid batteries.
It’s also worth noting that corrosion can occur faster in certain conditions, a phenomenon I like to call “hyper corrosion”. This happens when hydrogen gas escapes directly at the terminal due to a failed bushing, leading to rapid corrosion.
In summary, battery terminal corrosion is a result of chemical reactions involving battery acid, hydrogen gas, and metal terminals. Regular maintenance and cleaning can help keep this issue at bay and ensure the longevity of your battery.
What Happens If You Don’t Clean Battery Terminals?
As someone who’s been around batteries for a long time, I can tell you that neglecting your battery terminals can lead to some serious issues. Let’s dive into the effects of corrosion on battery performance.

B. Difficulty Starting Your Vehicle
One of the most common symptoms of corroded battery terminals is difficulty starting your vehicle. The corrosion can create resistance, making it harder for the electricity to pass from the battery to the starter. This can result in slow cranking or no start condition. I’ve had my fair share of early morning surprises thanks to this issue.
C. Electrical Issues
Corrosion can also lead to various electrical issues in your vehicle. This can range from flickering lights to electrical components not working properly. It’s like a domino effect – once one thing goes wrong, it’s only a matter of time before other issues start popping up.
D. Battery Swelling
In severe cases, corrosion can lead to battery swelling. This happens when the battery gets overcharged due to the resistance caused by the corrosion. The excess heat causes the battery to swell, which can lead to battery leakage or even explosion in extreme cases. And let me tell you, a battery explosion is not a pretty sight.
E. Damage to Battery and Surrounding Components
Lastly, if left unchecked, corrosion can cause damage not only to the battery but also to the surrounding components. The corrosive material can eat away at the metal, causing irreversible damage. This can lead to costly repairs and replacements.
So, as you can see, it’s crucial to keep those battery terminals clean. Not only will it ensure the optimal performance of your battery, but it will also save you from potential headaches down the line. Remember, a little maintenance goes a long way!
