When does your car battery need to be replaced?

The battery in a car is a rechargeable battery that provides the motor vehicle with the energy it needs to run electrical systems. The primary function of this battery, which is also known as a starting-lighting-ignition (SLI) battery, is to kickstart the vehicle’s engine.

10 Easy Steps For Changing Your Car Battery

The most essential task that a battery must complete is being able to kick-start a vehicle. If the battery in your car is completely empty or has a low charge, your vehicle will not start. In order to maintain the functionality of your vehicle, it is imperative that you are aware of when it is time to replace the battery in your vehicle. I have outlined in this article some warning signs that should be looked out for to determine whether or not your battery is close to dying, as well as some methods to determine when it is time to replace it. In addition to that, I will also provide you with some helpful information regarding the battery in your vehicle.

1. Warning signs that may indicate your battery is falling

In this section, as I just mentioned in the previous one, I will provide you with some warning indications that can assist you in determining whether or not it is necessary to replace the battery in your vehicle. There are many signs and indicators that you need to look out for, including the following:

Slow engine crank:

When you try to start the vehicle, the engine cranking is lethargic, and starting the vehicle takes a little bit more time than usual. This is a warning that the battery in your device needs to be examined or replaced.

Check engine light:

When your vehicle’s battery capacity is low, the check engine light may occasionally illuminate. In this scenario, the majority of drivers are likely to think it is a misunderstanding or that the issue will resolve itself. It is not something you should disregard; instead, you should consider having one of your certified technicians take a look at it.

Low battery fluid level:

Because most car batteries have a portion of the casing that is translucent, you will always be able to keep a close watch on the fluid level in your battery. If the fluid level in the battery is lower than the lead plates, it is time to have the battery and charging mechanism checked out.

The swelling, bloating battery case:

The casing for your battery appears to have just finished a very hearty dinner. Excessive heat is the culprit behind the swelling of your battery container, which in turn shortens the life of your battery.

There is a stinky, rotten egg smell:

The area around the battery has a strong stench of sulfur, similar to that of rotten eggs. This is due to the fact that the battery is seeping. Leaking is also the source of corrosion around the posts (which are the locations of the positive and negative cable connections). It’s possible that the grime needs to be cleaned off before your vehicle will turn over.

Old age:

The lifespan of your battery may extend well beyond three years. When it approaches the three-year mark, you should start conducting annual inspections to determine the current condition of it.
