Occasionally, you may be out of voltage while driving the car either on a highway or over a long route. It’s a rainy night or day, and you have to be on time. So in such situations, you have to change a car battery in the rain by yourself.

This can be risky somehow, but not to such an extent as to let your life be at risk.

Experts must adopt precautions to do in such a situation, and you must have to do.

In such a situation, when you are going to expose your battery to the rain for a short time, It will not affect your car battery. It will not even die or be corroded. The only problem is that of short circuits that occur when you turn on the engine.

The removal of car battery terminals from the car when the current is flowing can cause shock. Otherwise, changing the car battery in the rain is a safe procedure.

Symptoms of car battery draining:

When your car battery is draining or dead, the functions that are based on the car battery will not behave normally. Your car won’t start by turning the ignition. The led lights won’t turn or will start blinking.

The horn switchboard lights and all other lights are turned off. By physical appearance, the car battery may look normal, or maybe it is swollen. In all such cases, the replacement battery is the only solution left.

Precautions while changing car batteries in the rain:

As water is not good for the battery, so if you are changing the car battery in the rain, you must have to follow some precautions to prevent sparks and other dangers.

  • First of all, if you want to safely change the car battery, you have to park the car to a side where there is no heavy rain. Start your car by using jumper cables. Either if it works or helps you to start your car, you will be able to get yourself out of the strong wind and storm situation.
  • When the jump start does not work, cover all the battery electrical equipment and all other systems from the direct rain.
  • Cover your hand with plastic gloves to prevent any kind of electricity shock.
  • Turn off the ignition key and engine.
  • Proper handling of the dead battery in wet conditions.

The procedure of changing a dead battery with an average car battery:

After taking the basic precautions, you have to follow the following steps to change the dead car battery or spare battery.

1. Park your car on the side of the road:

The first step when your old battery is dead on a stormy and rainy night when you don’t even have a portable charger is to park the car on the side of the road. The parking in the center would be dangerous as if other drivers couldn’t see your car because of the rain.

Besides, parking the car to the side and in a safe place allows you to work and install the new battery in a comfortable way.

Parking to the side allows you or provides you with a spare room to put all the instruments to put over during the work or if you are going to wait for a mechanic.

2. Turn off the engine:

When you park your car to the side, then the next thing is that you have to turn off the engine of the vehicle.

This is the basic and initial step for the replacement. As the battery terminals provide the necessary power to the engine so, when the engine is running, the current flows through the vented car battery or maybe through the damaged cables.

The current holding cables, when exposed to the rain water, get wet. This can cause not a strong but an electric shock. This can be even more dangerous to the person who is working with the battery due to moisture-damaging posts.

3. Opening of Bumper:

When you turn off the car engine that is receiving enough power from the battery and put the battery at resting potential, then you have to open the car bumper or car hood. Pull the hood up inside, where all the heavy downpours, engine, and sealed car battery with rubber membrane waterproof casing are present.

To prevent the engine and all other systems except the car batteries, you have to cover the system from being wet. If all these systems become wet, this would have adverse effects on the car system. So after pulling the hood, it is compulsory to cover the electrical system.

4. Removal of old battery:

Now the next step is the removal of the old car batteries. The low-voltage car batteries are removed in a proper way. Car batteries have negative and positive terminals. Both these terminals, positive and negative terminals, are connected with wires that are used for the current transfer.

First of all, the negative terminal is removed from the positive terminal. This is done as suggested by the mechanics that prevent the shock by cutting the connection. When the terminals are removed, pull the battery out of the car.

5. Installation of new battery:

After the removal of the old battery that was creating difficulty in jumping start your car in heavy rain and in driving by turning off the lights and missing, the new battery is inserted in that place. A new battery would be available at any shop nearby.

If, in any case, the new battery is not available, you can use the old battery by charging properly with any kind of portable charger.

Jumper cables can also be helpful if you have another car or vehicle nearby. Otherwise, you must have to buy a new one.

To fix the new battery in place of the old one, first, connect the positive terminals to the battery and then follow the negative terminals. This is because the electricity of the battery light is the flow of electrons from the negative terminal, so the spark and sounds sluggish will not cause any serious harm.

However, a car battery that is 12 volts is not of soo high to create power short circuits to the extent that it will create adverse effects.

6. Checking of new car batteries:

After the installation of the new batteries, close the hood of the car and then start your car to test whether the new battery is properly fitted or installed and functions properly.

In all these scenarios, the wet condition, power, and rainwater must be kept in view so that these must not expose so much to the battery.

No external water, but the acid levels of the batteries can also cause the wet condition that should be a double check. If the car is dry for a long time, it will cause the batteries to drain, but if the acid level in the batteries exceeds the limit from the normal, it can also cause the batteries to drain suddenly.

Jump starting your car in the rain:

You can also jump-start your car battery in the rain despite changing the car battery. Jump starting the car battery is a technique to safely charge the car batteries. If there is another vehicle, jumper cables, or a portable charger available, you can do jump-starting.

For jump starting, the jumper cables are connected tightly to the batteries of the car that is going to die, with the other end attached to the batteries that are doing to provide the jump start power.

This provides enough power that can start the car and can be used as a reciprocal to change a car battery. But it is not the proper and permanent solution.


A dead battery can be changed or replaced with new batteries even in the rain, and the rainwater does not have any kind of adverse effect on the car batteries. But the constant exposure of the water to the battery can cause an electric shock.

Not only the rainwater but the acid inside the batteries, when exceeded, can cause danger. Although, in any case, jump starting can be a solution to the replacement, changing car batteries in the rain is a safe procedure to some extent.

Does rain damage your car battery

Technically rain does not damage your car battery. The only effect of rain on your battery is that it makes your car battery wet. This condition won’t decrease the car battery’s performance, but it sometimes causes an electric shock.

Is it safe to change the car battery while running

No, it is not safe to remove your car battery while your car is running. When the car engine is working, the current flows through the car battery and engine that causes the electric shock.

So it is compulsory to turn off the car engine before removal of the car battery power to prevent any kind of hazards and dangers.

How long does it take a car battery to dry out

If you let your car battery and car off for a while, the car battery will dry out, and the battery will not function properly. To recharge your car battery and to keep your battery active, you have to turn it on and drive the car for at least 30 minutes a week. By doing this, your car battery will recharge and function properly.

Can water damage the drained battery

Water usually does not drain the battery in rainy weather. But sometimes, the water on the car battery that is not dried properly can degrade your car battery as this may cause corrosion over the sensitive points or over the terminals.

Can You Supercharge in the Rain

In electric cars, there is a proper system developed in the cars that allow you to supercharge the car battery in the rain. But you must keep the charging spot dry and prevent rainwater from entering as that may damage the electrical system of the car. So it is better not to supercharge your car in the rain.

What happens if the car battery sits in the water

If a car battery is kept in the water fully or partially for a while, this can cause the car battery chargers and terminals to corrode and eventually die. The rainy season can drain the battery, but the rainwater for a while can not affect it.

Can I Drive My Car in the Rain With a Weak Battery

Yes, you can drive your car in the rain with a low-voltage battery, but only when you have an emergency situation. If you are planning to go outside just for fun and you have a low battery. It is recommended not to go out.

Only because there is a chance that your car won’t start at any time or it may even cause driving complications., To overcome such problems, It is recommended not to drive a car with a weak battery in the rain.

Is It a Problem If the Car Battery Is Wet on Top

Yes, it is a problem if your car battery is wet on the top. If the car battery is wet from the top, it can cause the battery to corrosion, and eventually, you have to change the car battery, which also happens when the car dries. The other result of corrosion is the jump start. The wetting of car batteries may be the rain effect.
