Can You Change A Car Battery In The Rain? (Is It Safe?)

I have seen lots of car owners sharing their experience of dealing with dead car batteries in the middle of heavy rain. And, they wonder, can you change a car battery in the rain?

The answer is yes, you can replace your car battery with a good one in the rain. But you have to do it properly can carefully. Otherwise, you may get shocks.

You have got the answer but don’t go away yet. Later in this article, I have explained how you can stay safe while changing the battery in wet conditions. There is some additional info too. So, let’s get started.

Can You Change A Car Battery in The Rain?

A straight yes doesn’t show the full picture here. You have to keep some facts in mind. While changing your car battery in wet conditions, be very careful.

Though the battery’s DC is way less powerful than AC, it still has some damaging abilities.  

Voltage is not what kills us; it is the amount of electricity or current.

According to the ScienceABC, 100mA current forced through the body for 2 seconds can be fatal.

And, you are well aware that your car battery holds enough power to be fatal. An average car battery holds almost 550 Amps.

The danger is when you touch both terminals with wet hands or somehow complete the circuit.

You don’t have to worry about the dead battery but the good one you are replacing with.

Also, the water between the terminals may carry a small amount of electricity but it won’t give you a shock.

How Can You Safely Change Car Battery in Rain?

Let me tell you the steps in the simplest way possible.

  1. First of all, pull your car to one side of the road. It will be best if you can find a parking spot.
  2. Then, open the hood, and keep it secure so that strong wind can’t damage it. Also, don’t open the hood without turning off the engine.
  3. The best practice is to cover the hood area with a tarp. Now, disconnect the dead battery starting from the negative terminal.
  4. After taking out the dead battery and putting down that good one, connect the cables. Here, you have to start with the positive terminal.
  5. Finally, turn on the engine and you are good to go.

Lastly, dry the top of the battery as soon as you go to your home or under a roof. Otherwise, keeping the terminals wet for a long time can introduce rust.

Is It Safe to Jump Start A Car While It Is Raining?

Yes, it is as safe to jump-start a car as changing the battery in rain. Rainwater doesn’t short the jumper cables.

Just be careful about not touching both ends of the jumper cables while they are connected to the battery, and you will be fine.

You can also charge a battery under extreme rain or snowfall. The car battery manufacturers design their products keeping all situations in mind.

No matter what, having a dead battery in the middle of nowhere is very painful. So, keep the health of the car battery in check regularly.

Frequently Asked Questions(FAQs):

Will, It Be A Problem If The Car Battery Is Wet On Top?

You can safely charge your car battery in the rain without facing any difficulties. It is because the engineers design the system to withstand wet conditions or rain.

What Happens If A Car Battery Gets Submerged In Water?

Because of the sealed top of the car batteries, there won’t be any problem if it gets submerged in water. But keeping it that for too long can introduce rust and leakage.

Can you supercharge in the rain?

Supercharging Tesla or any electric car battery in rain and snow is possible. However, the charging time may slightly vary depending on the weather condition.


Can you change a car battery in the rain? Yes, of course, you can but don’t do it unless it is absolutely necessary.
