Bad Cell in Car Battery Symptoms- Causes, Cycle Life and Fixing

Bad Cell in Car Battery Symptoms- Causes, Cycle Life and Fixing

Page view

The role of batteries in cars is very important as the cars cannot start without the battery. Although it has significant importance, this is one of the most ignored parts of the car. As a result of ignoring the batteries, one thing that happens is that the battery fails to provide power to the car and one of its biggest reasons is the bad cell in the car battery.

So, here we will discuss what causes bad cells in car batteries and we will also discuss some other useful facts about the bad cells of car batteries.

What are some causes of a bad cell in the car battery?

This is something that people are looking to know about so that they can get rid of the facts that cause dead cells in the car battery. There are a lot of reasons why the battery cell goes bad, but the most common ones are mentioned here.

Bad Electrolyte

Whether you are using the bad electrolyte that can be a mixture of raw acid with distilled water, using tap water in the batteries, or the level of electrolyte in your batteries is very low. Any of these can be the cause of the battery cell to go bad.

It is because the batteries are designed in such a way that the plates are electrically connected with the help of an electrolyte and this electrolyte must be free of any types of contaminants.

Additionally, the electrolyte must be made from the best quality materials and its level inside the battery must also be maintained. So, when any of these things is ignored while regularly using the battery, one or more cells inside the battery can go bad.

Intensive Vibration or Collision

Apart from the issues related to the electrolyte of the battery, the collisions or vibrations that are unbearable for the battery can also cause a cell to go bad or even dead. It is because the battery cells are made with plates that are not meant to come in contact with one another.

However, these collisions or vibrations may cause the battery plates to come in contact and this causes short battery plates. When this happens, the battery cell is not good anymore.

How much life can you expect from a car battery with a bad cell?

When people get batteries with bad cells, one of the most asked questions is how long will it last in this condition. As an answer to this question, one thing that we can say is that things will depend on the condition of your battery.

However, one thing that can be said is that if you discover the problem in the early stages and get it recovered, then the battery can last for some years or so. So, here we will discuss different conditions of the battery and the time for which the battery can last.

The battery cell is bad because of electrolyte.

If the battery cell is bad because of the electrolyte present in the battery, then this is something good because the battery is not in very bad condition. In this condition, the battery will not be able to perform well because of one cell or more and it will even be impossible to start the car with this battery. It is because the battery voltage will not be getting above 10.5 volts.

So, in this case, if the battery is repaired at the right time, it can easily last for about 10 years if the battery is new. Otherwise, you can calculate the expected life of the good battery and the repaired battery can last as long as the expected life.

The battery cell is bad because of other issues.

If the battery cell is bad because of other reasons like collision or vibration, then the chances of the battery getting repaired is very low. This battery cell condition is because of the following reasons.

  • The process is not feasible for everyone.
  • The process is not cost-efficient.
  • The whole process required a lot of time, tools, skill, and dangerous level expertise.

So, in this case, the battery can last no longer.

Can you fix a bad cell in a car battery?

Yes, when you get a battery with a bad cell, this is a condition where it can be easily fixed. However, this is not the case with all the batteries. This is only possible for the batteries where the issue is with the electrolyte. So, here we will discuss how you can fix the bad cell in a battery.

Things required for the procedure.

The following are the things that you need for this process.

  • Protection equipment for hands, face, and eyes
  • Tools
  • Cleaning agents
  • baking soda and Epsom salt
  • Distilled water
  • Cleaning cloth

The Steps You Need to Follow

The following are the steps that are required for b followed for fixing the bad cell in a car battery.

1.Taking the battery out and cleaning it.

Carefully take the battery out of the car and make sure that it is clean everywhere. You can use the cleaning detergents with water to clean the grease from the battery. The corrosion and the acid of the battery can be removed with the help of paste of water and baking soda. This will also help to keep the battery free from contaminants during the process.

2.Preparing the electrolyte.

Now you will need to prepare the battery electrolyte. For this, you can add 120 grams of Epsom salt in 1 liter of water and stir it well. If you are unable to do this, you can also buy ready to use battery acid from any nearby store.

3.Filling the battery.

Now carefully fill the battery to the maximum level and make sure that every cell is well filed. Also, make sure to not overfill any of the cells.

4.Charging the battery.

Now you will need to slow charge the battery for about 24 to 36 hours, and it will be good to go.

Conclusion

Batteries play an important role for the car because without the battery most of the cards are useless. Most of the time car users don’t even know if the battery is dead or there is an issue with only one cell. So, here we discussed all about the bad cells in car batteries and how you can fix them.
