How to Change a Car Battery: A Beginner’s Guide

“A car is a matter of fate, a battery is a matter of life” – this folk saying is true, because the battery is the soul of every vehicle, playing an important role in starting the engine and providing power to the electronic devices on the car. When the battery “runs out of steam”, your car will be “powerless” and unable to move, putting you in a frustrating situation. So how do you change a car battery effectively, quickly, and safely? Let’s find out with Hanoi Truck!

Why Change Your Car Battery?

Car batteries, like people, have a certain “lifespan”. After a period of use, the battery will wear out and reduce its operating efficiency, leading to phenomena such as:

• Difficulty starting the car, having to crank the engine several times before it starts.
• Dim or flickering headlights, taillights, and turn signals.
• Crackling or low volume from the radio, speakers, and car horn.
• Error displays or malfunctions on the dashboard.
• The car suddenly “runs out of power” while driving.

Signs Your Car Battery Needs Replacing

Your car battery needs replacing when:

• The battery’s lifespan has exceeded 3-5 years (depending on the manufacturer and usage conditions).
• The battery is swollen, leaking, or shows signs of corrosion.
• The battery voltage is lower than the permissible level (usually below 12V).
• The battery has a foul odor or makes unusual noises.

Simple Guide to Changing a Car Battery

Preparation:

1. New battery: Choose a battery that is suitable for your car model, with specifications that are equivalent to or higher than the old battery.
2. Tools: Pliers, wrench, dry cloth, protective gloves.
3. Safety precautions: Wear eye protection, protective gloves, and avoid direct contact with battery acid.

Steps to Change the Battery:

1. Disconnect the negative (-) terminal of the battery first: The negative terminal is usually marked with a “-” sign or black color.
2. Disconnect the positive (+) terminal of the battery: The positive terminal is usually marked with a “+” sign or red color.
3. Remove the old battery: Use a wrench to remove the screws that secure the battery, then gently lift the battery out of the car.
4. Install the new battery: Place the new battery in the old position, making sure that the (+) and (-) terminals are correctly positioned.
5. Connect the positive (+) terminal of the new battery: Tighten the screws securing the positive terminal.
6. Connect the negative (-) terminal of the new battery: Tighten the screws securing the negative terminal.

Important Notes When Changing a Car Battery

• Always disconnect the negative (-) terminal first before removing or installing the battery.
• Avoid touching battery acid, as it can cause skin burns.
• Store the battery in a dry, ventilated place, away from high temperatures.
• Regularly check the battery’s electrolyte level and add distilled water when necessary.
