What Causes Battery Corrosion

Batteries are a common item that can be found in most households. They are used to power a variety of devices, such as cars, phones, and laptops. While batteries are incredibly useful, they can also be quite dangerous. One of the dangers of batteries is battery corrosion. In this blog post, we will discuss what causes battery corrosion and how to prevent it from happening.

What is the common cause of battery corrosion?

The common cause of battery corrosion is leaving a battery in a discharged state. When a battery is discharged, the sulphuric acid that is used to create electrical current inside the battery starts to eat away at the lead plates inside the battery. This causes tiny holes to form in the plates and leads to a rapid corrosion of the battery.

Another common cause of battery corrosion is acid leakage from the cells. This can be caused by a number of factors, including age and extreme temperatures. In addition, if the battery is not properly sealed, moisture can enter the casing and also contribute to corrosion.

And also, one possible cause is overcharging. Overcharging can cause the electrolyte to break down, which leads to gas formation and eventual boiling of the electrolyte. This gas loot escapes from the battery, and it can corrode metal parts in close proximity.

Knowing these causes of battery corrosion can help you to take steps to prevent it from happening.

How do I keep my battery terminals from corroding?

The best way to prevent your battery terminals from corroding is to clean them. A corrosion build-up can reduce the electrical contact between the battery terminal and the wire, leading to reduced battery performance.

-You can clean your battery terminals with a mixture of baking soda and water. Baking soda is a natural cleanser, and it will help remove any built-up corrosion from the terminals. Be sure to rinse the baking soda off thoroughly afterward, and then dry the terminals with a clean cloth.

Before using the battery again, make sure to charge it fully so that it does not have any other areas where there may be corrosion occurring due to a lack of power supply for long periods at a time. It is also important to store your batteries in a cool place away from extreme temperatures such as direct sunlight or heaters, as they speed up corrosion.

-Ensure that you always charge your batteries properly and keep them in a dry place when not in use. In addition, if your battery starts to exhibit signs of corrosion, replace it immediately. 

-Another option is to use a commercially available terminal cleaner or protector. These products are designed specifically for cleaning and protecting battery terminals from corrosion. Just be sure to follow the manufacturer's instructions carefully when using these products.

These are some simple steps that you can take to help prevent battery corrosion and keep your batteries performing at their best.

Does battery corrosion mean bad battery?

Not necessarily. Corrosion on a battery's terminals can be caused by a number of things, including the accumulation of dirt and debris, contact with acids or other liquids, or even weather conditions. But corrosion is not always an indication that a battery is bad.

Most corrosion on batteries is actually fairly harmless and can be easily cleaned up with a little bit of baking soda and water. However, if you do see significant corrosion on your battery's terminals, it's always best to check with a professional to make sure the battery is still in good condition and hasn't begun to wear down.

Can battery corrosion be fixed?

Yes, it can be fixed. However, the corrosion may have caused some damage that is beyond repair, and in such cases, a new battery will need to be installed.

If the corrosion is minor, it can often be cleaned up and removed using a simple solution of baking soda and water. If the corrosion has caused significant damage to the battery's cells, or if the corrosion has penetrated the battery cells, then it may not be possible to fix it, and a new battery will need to be installed. In either case, it's important to take the battery to a qualified technician for inspection and repair/replacement if necessary.

Conclusion

Corrosion can happen to any battery and if not attended properly can lead to some serious inconveniences. Being aware of the causes and symptoms of battery corrosion, you can take steps to prevent it from happening in the first place or address it quickly if it does occur. We hope that this article has given you some useful information about what causes battery corrosion and how to prevent it.
