1. Leakage of electrolytes

A fluid leakage of the car is always a possibility. There is corrosion when you notice electrolytes leaking out and accumulates on the battery terminals. This may be caused by lack of maintenance and also damages to the battery. This happens to acid batteries that are of sealed lead type. When you notice flooding in the battery, there is higher percentage that the electrolytes will start spilling out if you don’t fill the battery water meticulously. And so when electrolytes accumulate, it causes corrosion. This can also happen to batteries like the lithium ion batteries that hybrid cars make use of.

2. Battery overfull

This is one of the reason you are facing battery terminal corrosion. When the battery water is too much, it causes trouble. You just have to fill it up to the highest marker and make a stop there. The terminals are made of metals so any more that gets to the vents will corrode the metal.

3. Copper clamps reaction

This is one of the reason you are facing battery terminal corrosion. If you have any idea about chemistry, you will know that metal does not corrode on its own. The clamp that connects the wires to the battery is made up of copper. But do you know that the current that passes through metal produces copper sulfate that causes battery terminal corrosion. You will notice a precipitate that is bluish in color that is forming around the terminals of the battery. So when this happens, it was make the battery weak, have a shorter lifespan, and also harm the health of the battery.

4. Overcharging

This is also one of the reason you are facing battery terminal corrosion. There a saying that too much everything is bad and that also applies to your battery also because when you charge your battery too much or over charge your battery, it is dangerous for the lifespan of your battery. Overcharging makes the battery overheat after this it leads to corrosion. After this happens, kinetic energy stores which will make the volume expand. Another thing is that be it a flooded kind or a sealed type, electrolyte will be pushed out of the cracks or vents and then this leads to the terminals feeling the full force of this which later makes it corrode.

5. Age of the battery

If you have been using the same car for a number of years without changing it then you should be expecting to face battery terminal corrosion. I bet the reason why you haven’t changed it is that you do not know that car batteries come with expiry dates. The amount of time your car battery can serve is 5 years tops, and that’s even when you maintain the car like you should. So guys just know that you should be expecting corrosion even with this. The engine of your car will need to tell you if you do not want to change it by not working well, so please do not hesitate to change your battery when the time is up.
