The signs of a weak or dying car battery include: dim headlights, slow engine cranking, or difficulty starting the vehicle.
Ignoring these warning signs can lead to frustrating breakdowns and costly repairs.
A bad battery the issues that affects your ability to start the car but also impacts other vital systems. For example, the alternator and starter motor.
Therefore, it’s essential for every responsible car owner to understand how to check your car battery’s life.
The information contained here about your car’s battery health, ensures you of a smooth driving experience.
Additionally, you’ll be able to avoid unnecessary inconveniences.
How to check car battery life.
Firstly, what is the reason for performing a car battery life check? Proceeding before answering this question means you won’t quite get it.
You need to perform a car battery life check to ascertain it health condition and performance. Therefore, at the end of this session you will understand everything involved in this process.
Practicing some of these points will help the car battery last long even without driving for extended periods.
Tools required for checking the battery’s health.
These are the necessary tools you need before proceeding with the car battery health check. Remember to also implement some safety precautions to prevent injuries.
- Wire brush.
- A digital multi-meter.
- Battery terminal cleaner.
- Protective gloves.
1). Check battery age.
Manufacturers include a date code on all car batteries to indicate when the battery was manufactured. Check out the sticker on the battery for this information.
The date code is a combination of letters denoting the month and numbers representing the year.
Additionally, the car battery age affects its health after you have used it for a given mileage. During this time, there are many symptoms that will indicate that it’s car battery replacement time.
