Can A Car Battery Freeze

Otherwise, they would be in a lot of troubles during winter months. As you all know that a lot of things get frozen during winter, there is one question arise, Can a car battery freeze? The answer is, Yes, it can. Extreme cold temperature can freeze the battery of your car making it difficult for you to start the engine. Now let’s find out in what condition your car battery freezes.

Extremely Cold Temperature

If the temperature of your surrounding is extremely cold which happens sometimes in your areas during winter months can affect your car battery too. The water portion of the electrolyte or electro-chemical which is found in your battery freezes could not produce enough voltage to start your car.

The Charging Capacity of The Battery

It has tested that if your battery is fully charged it will never freeze until the temperature drops minus 76°F but if your car has a fully discharged battery then it could start freezing at minus 32°F. But don’t think that there is a big difference between a fully charged and discharged the battery as for the battery is 12-volts only it is a matter of 8/10 of a volt difference.

The Quality of The Battery and The Connection

If the battery installed in your car has crossed it valid time, then you’ll find the battery cannot sustain a charge for too long. Besides, if the charging system is below par then also charge starts falling quickly which may freeze the battery in freezing temperature.

Damaged Cells of The Battery

A battery of your car has six cells. If one of them is damaged the voltage of the whole battery will reduce below 12-volts and the battery is fully discharged. In this way, your battery will be not capable enough to bear the sub-zero temperature and started freezing.

The Ways for Keeping Your Battery from Freezing

1. Precaution should be taken with your car battery before winter months. You need to clean the battery cables and terminals by detaching the battery from the terminals. You need the terminal cleaner and a brush for this job. After the cleaning job is done rub them with a dry rag.

Find the Actual Condition of The Battery

At first, check the battery. If you find the electrolyte chemical into the battery is still diluted state then be relaxed, for your battery is still working without freezing. If it is frozen then you need to melt before use. Unless it could explode as it has a crack on the case outside.

Connect the Car with a Block Heater

In most of the cars in extremely cold regions are equipped with a block heater. This helps the battery melting quickly. All you need to plug into the car for at least 2-3 hours. This would certainly make your frozen battery fit for working again.

Unload the Frozen Battery from the Car

If still, you find your battery is frozen then remove it from the car. Open the battery cover; detach the cables and keep the battery in a warm place allow the battery to melt. In this way, you’re might be ready to run again.

Keep Your Car to the Heated Area

Sometimes you’re not confident enough to remove the battery for melting the harden fluid inside. In that case, try to push your car inside the garage where it gets at least some warmth so that the battery will get a chance to melt easily.

Test the Battery and Charge it

After following all the directions that are told so far, finally, it is time for you to test the frozen battery if it is melted or not. Even you have also to see if any crack is there before connecting the charger.

Few Important Tips

  1. If your car is still in the garage, then to provide power and to avoid freezing plug it to the charger if your car has a block heater.
  2. The next important thing what you need to do is to keep the battery post frequently to prevent them from corrosions.
