If you’ve ever had a car battery go dead, you know it usually happens at the worst possible time. You can prevent a dead battery by taking a few simple actions to tell if your Mitsubishi needs a new one. One of the easiest ways to determine your vehicle’s battery level is to test it. Take your vehicle to a Mitsubishi dealership or an auto repair shop, where a technician can test the battery to determine its power level. By testing your battery at least once a year, you’ll be prepared to replace it before it goes dead.

Along with diagnostic testing, there are other ways to recognize if it may be time to change the battery. If your Mitsubishi has trouble starting or ever fails to start, it could be a sign of a low battery. Of course, if the battery ever goes completely dead, it’s important to replace it, even if the vehicle runs again after jump-starting the engine. After changing the battery, you can expect a new one to last for four to six years.

Tools You Need To Change a Battery in a Mitsubishi

If you decide to change the battery in your Mitsubishi yourself, you’ll need a few tools to get started. These include:

  • A screwdriver to remove the air inlet.
  • A 10mm socket wrench to loosen the bracket holding the battery.
  • A terminal brush to clean the battery area and remove any corrosive buildup.
  • A battery terminal protector to prevent corrosion and extend the battery life.
  • A new battery to replace the old one.

Process of Changing a Battery in a Mitsubishi

When you need a new battery in your Mitsubishi, it’s fairly simple to change it yourself. While the steps can vary slightly based on the vehicle you have, they’re typically very similar, whether you’re driving an Outlander, Mirage, or another model. Here’s how you can change a battery in a Mitsubishi:

Locate the Battery

If you’re replacing the battery before it’s already dead, make sure you turn off the vehicle before you begin. Open the hood by using the hood release, which you can find underneath the dashboard. Keep the hood propped open while you work. Locate the battery, which will be on the driver’s side of the engine bay.

Check the Air Intake

Some Mitsubishis have an engine air intake hose on top of the battery. If your model has this hose, locate the two plastic clips on the air inlet and remove them with a screwdriver. Pull forward on the air intake hose to remove it, using a screwdriver if necessary.

Remove the Battery Bracket

To remove the battery bracket, use your 10mm socket wrench to loosen the nuts on the top of the bracket. Place the nuts somewhere safe so you can put them back on later. Remove the bracket holding the battery.

Take Out the Old Battery

Find the battery’s positive and negative cables. Use the 10mm socket wrench to loosen the clamp on the negative cable. Move the negative cable aside and follow the same process for the positive cable. After you’ve disconnected both the negative and positive terminals, you can take out the old battery. Go slowly to check for battery leaks, which can be highly dangerous.

Clean the Battery Terminal

After removing the battery, use a terminal brush to clean the battery terminal thoroughly. This step can help remove any corrosive buildup from the old battery.

Replace the Battery

Set the new battery in place and connect the positive cable first. Tighten the clamp back into place. After you’ve connected the positive terminal, replace the battery bracket and tighten the nuts on top of the bracket. Then, connect the negative battery cable following the same process as the positive cable. Once you’ve replaced the battery, use a terminal protector on the positive and negative terminals. If you removed an air intake hose, replace and tighten it to make sure it’s secure.

Battery Warning Light in a Mitsubishi

Most Mitsubishi models will warn drivers if there’s a problem with the battery by flashing a warning light. This light will appear on your dashboard as a picture of a battery or the word “battery.” If you see this light appear, it typically means there’s an issue with the vehicle’s battery or alternator, which charges the battery. If you struggle to start the vehicle and the battery light stays on while you drive, it often means it’s time for a new battery.

Tips for Changing a Battery in a Mitsubishi

When replacing a vehicle’s battery, you can use a few tips to help you stay safe and follow the process correctly. Here are some tips for changing the battery in a Mitsubishi:

  • Tighten the terminals: When you reconnect the positive and negative cables, make sure you tighten the terminals. If they’re loose, the battery may not charge and won’t be able to start the engine.
  • Purchase the right battery: It’s important to purchase the right size battery for your Mitsubishi. Check the owner’s manual or look at the current battery to determine the one you should buy.
  • Dress appropriately: Make sure you wear gloves and safety glasses when you change the battery. If you have long hair, tie it back so it doesn’t get caught.
