Car and vehicle batteries are susceptible. A slight change or corrosion may cause your car to stall and stop working. Proper battery maintenance is needed to make it work efficiently. But is corrosion a severe thing that car owner should worry about their batteries? Let mwe find out!
Can corroded battery terminals cause a car not to start? Yes, corrosion on the battery terminals may cause a vehicle to stop working. The reason for this is because corrosion may cause a bad connection to the battery.
When the battery is not well-connected, it may not work well, and the car will not start. To get the best of the battery’s performance, it should have good metal to metal connection. There should be no rust nor oxidation.
Loose contacts on the battery terminals are more likely the cause of poor starting or no start at all. Make sure that you keep the battery terminals and poles clean and free from rust and corrosion brought about by the oxidation.
What Causes Battery Corrosion?
● Hydrogen Gas. Battery corrosion is a product of the hydrogen gas coming from the battery acid. This gas is mixed with other agents in the atmosphere, which comes from the hood and creates the corrosion that you find on the battery terminals.
When the corrosion happens on the negative terminal of the battery, it might be undercharging. If the corrosion occurs on the positive side, there is overcharging. Many times you will find the corrosion happening on the battery’s negative side since most cells are undercharged.
● Electrolyte Leaks. An electrolyte is similar to lead-acid batteries. Due to old age and damage, the battery’s electrolyte may leak and build-up on the terminals of the cell. The probability of leaking the electrolyte may rise if you overfill the battery with water.
● Copper Clamps Corrosion. Copper is considered to be a good conductor and will not corrode quickly. But when electrical currents are passing through these copper terminals, copper sulfate will produce, and that leads to the corrosion of the battery terminals.
● Over Charging and Filling. Once you overfill the battery with water, it will be the cause of electrolyte leaks going through the vents and will eventually corrode the battery terminals. Make sure that you only put the exact amount of water in the battery.
Overcharging the battery will produce the same thing. Electrolytes will leak once it is charged over the kinetic energy and may overflow to the battery terminals which will then cause the corrosion.
You have to clean the corrosion right away to prevent it from further building-up. Prevention from corrosion can only lessen or slow down. Corrosion will happen if you fail to maintain your battery at a regular time. Slowing down the corrosion can be done by applying grease on the battery terminals.
You need not overdo the application, but you have to make sure that you cover the entire metal part of the pole. In time, corrosion will build up again and break down the grease. Therefore, regular cleaning is required to prevent it from building up.

Can Corrosion be the Cause of a Dead Battery?
Yes, corrosion is one of the major causes of a dead battery. A corroded battery will prevent it from topping off the charging system of the cell while driving. It will also cause loose connections on the battery poles or terminals, which can also be a significant problem.
I will mention here some of the reasons why car batteries die. You will find out that one of the things discussed here is corrosion.
Major Causes Why a Car Battery Keeps Dying
There are plenty of reasons why a car or vehicle battery keeps on dying. It could be a lack of proper maintenance and care for your battery. However, these reasons are some of the factors that contribute to a dead battery.
1. Leaving the headlights on overnight
Headlights or dome lights that were left on overnight can drain your battery and leave it dead the next day. You have to check your interior lights after parking thoroughly. Most headlights can withstand being on for a short time, but an inadequate electrical system may turn them on permanently.
2. Weak Battery
A weak battery may not be able to hold its charge longer. When the battery is already weak and unsatisfactory, even the slightest drains like the memory of your car stereo may leave your car battery dead.
3. Battery Corrosions
Corrosions on your battery may leave a poor or bad connection. A loose connection may cause your battery to stop working.
4. Parasitic Drains
Parasitic drain is enough to kill your battery. This parasitic drain may come from your trunk light that turns on and left permanently on when it should not be.
5. Extreme Weather Temperatures
A good battery may never be affected by the changes in weather temperature. However, an already weak battery may show failure in extreme weather conditions.
6. Charging Problems
When the battery dies while you drive, it is a big possibility that your battery has charging problems. A loose belt or a worn-out tensioner will prevent your alternator from working correctly.
How to Prevent Battery Terminal Corrosion
Here are some preventive measures to help you in maintaining your battery against corrosion.
1. Compression of Copper Terminals
Copper terminals are one of the best materials you can use against corrosion. If you have a copper terminal, it will ensure that your entire clamp will get connected to the electric current.
2. Charging the Battery
One of the significant causes of corrosion is that the battery is either over or undercharged. Battery manufacturers often provide a manual that highlights the recommended voltage for the battery. You should strictly follow the recommendation if you do not want your batteries to corrode.
3. Anti-Corrosion Sprays
Some sprays are readily available in the market that works against battery corrosion. Spraying the battery terminals with this anti-corrosive sprays will help prevent the build-up. You may also opt to use grease if you find the showers high on your budget. There are also some coated pads which can also be used against corrosion of batteries’ terminals.
Symptoms of battery terminal vorrosion below:
● Hard-Starting
● Visible Battery Corrosion
● Loss of Power
How Much Does a Battery Terminal Cost?
Battery terminal will only cost you around $20 or less. It can be easily replaced in about an hour.
Based on the facts that I have presented to you, you can now positively say that negligence on your part to maintain your battery will cause corrosion. It is positive that a corroded battery terminal may cause a car not to start.
