How Long Does It Takes To Replace A Car Battery

The car battery is a silent member of the automotive team that keeps your vehicle running. Battery power that allows a vehicle to start upon first turn is indeed a joy, but they don’t last a lifetime. An automobile’s electrical system is powered by the battery. In order for the car to start and run, it is the primary source of electricity. Here we have provided information about how long it takes to replace a battery.

Replacement time for a car battery

Typically, the process takes between fifteen to thirty minutes. There are several factors that affect how long the process takes depending on the car model, battery access, and removal from the vehicle. Furthermore, it is usually based on the experience of the person carrying out the task. It may take longer, for instance, if it is the first time the battery has been changed, than if the mechanic had done it before.

Procedure for replacing a battery

The lifespan of an automobile battery is limited. Changing the battery is considered an easy task if carried out with care and safety. Following are instructions that will help you to understand how to easily change your car battery:

  • First turn off the car and engage the brake to put it in packing mode.
  • Ensure that no electricity has been drawn from the battery by removing the keys from the ignition.
  • Make sure you wear a safety suit in order to prevent hand burns caused by battery acids. To protect your hands and eyes, put on gloves and safety goggles, then put on the hood.
  • Locate where the battery is located under the hood. It can usually be found near the windshield on the left side. The device is connected to two cables.
  • There is one cable that is colored (black) (-). Ground (negative) is at this terminal. Before disconnecting this cable, make sure it is unplugged. To avoid short circuits, always disconnect this cable first.
  • You can disconnect the other cable, which is the positive (red) (+) terminal, by loosening the clamp on the positive cable, and then reconnect it.
  • There is a bolted bracket securing the battery in place at the bottom of the battery. It can be loosened with a wrench.
  • Set aside the battery on a concrete surface once you have removed it from the car.
  • Sand the battery cables with sandpaper before removing the old battery and replacing it with a new one. This will help you to remove any residues and build-up that may have accumulated from the old battery.
  • When buying a new battery, be sure it has the same dimensions and specifications as your old one.
  • With the 13-mm socket wrench, tighten the bolt after installing the new battery and locking it in place with the bracket. A dielectric grease can be applied to the terminals to prevent corrosion and acidic build-up.
  • Before you reconnect the negative cable, reconnect the positive. The cable must be placed over the terminal before the 10-mm bolt can be tightened with a socket wrench.
  • If the terminal is equipped with a cover, you can put it over the terminal.
  • Reconnect the negative cable next by placing the wire on the negative terminal. The bolt should now be tightened with the socket wrench.
  • Ensure that the battery is securely plugged in, and that neither the cable nor the battery is moving.
  • To start your car, close the hood and push the starter button. Inspect everything to ensure that it works properly.

Symptoms of a bad Car Battery

Listed below are the symptoms of a faulty car battery:

Crank speed

Car batteries provide the power necessary to start your vehicle. Power cannot be derived from any other source. The CCA (cold cranking amp) of your battery decides how much power you need to crank your engine.

It is highly likely that you are quickly applying more power to the engine by turning the ignition several times at the beginning of the day, which can be related to either battery terminal issues or parasitic draw. It is possible to notice that the engine cranks more slowly than usual when you first start it.

If it takes a long time for the engine to start, the battery is not producing enough power. A low battery voltage may indicate that a new battery is needed.

Electrical component’s power supply

The modern automobile has an interesting feature: the batteries supply the power to the electronic components, including power windows, doors, wipers, headlights, speakers, and other smaller components. When these components become less functional, the power of the battery is reduced.

Swelling of the battery case

One of the best ways to detect a problem with the battery is to observe how it swells. In most cases, the swelling occurs when a chemical reaction is unanticipated. As a result of the chemical reactions in the battery, it produces a lot of heat and, therefore, reduces its operating life. Having this problem on a regular basis indicates your car battery is dying.

Boosting or starting the engine

If you jump-start your battery frequently, it could be seriously damaged. If the battery is being charged three times a week, it should already be replaced. A battery can be damaged not only by frequent jump-starting, but by damaging its alternator as well.


Battery work must be taken into consideration by the mechanic. The battery can be overloaded with functions, which reduces its life span. A car battery needs to be replaced very quickly if you’re doing the replacement work yourself.

It will take less time if you hire an experienced mechanic, but you will feel a greater sense of achievement and satisfaction if you do it yourself. Car batteries can be replaced in 15 to 30 minutes, depending on the car. Along with the replacement time of the battery, we have discussed the steps to take when replacing the battery in a car and what signs to look for when determining if the battery is bad.
