2. The battery is an electromechanical component of your car which is generally supply the electrical power needed by your car.

3. Your car can generate power through its several components, but the engine is completely dependent on the battery.

4. If the battery of your car has any types of problem then it will affect many devices in your car because those devices depend on the battery.

5. It's your duty is to test the battery of your car regularly and maintaining it for enhancing its life and improve the performance.

6. Here the below points helps you to test the battery of your car adequately:-

8. Handling the battery of your car can be a hazardous process because it contains sulfuric acid for operating the chemical inside them.

9. So for testing the battery of your car, it's very important to wear the protective gloves, clothing and a safety goggle.

10. In this way, you can protect your body from the electrical hazards because it may possibly create injuries in your body while testing the battery.

12. To test the battery of your car, arm yourself with a voltmeter and set the dials on the 0-50 volt range.

13. Then disconnect the battery from the car by following the instructions given in your cars owner's manual.

14. For doing it you need to attach a 9V alkaline battery to the car PCM. Otherwise, it will lose its programmed settings.

16. First, set the voltmeter to DC and connect the positive red lead of the voltmeter to the positive battery terminal of the car.

17. Then connect the black lead of the voltmeter to the negative battery terminal of the car. After that check the voltage level.

18. If the range is 12.6 to 12.8, then the battery is adequately charged. Below that range means the battery is not charging. Then you needs to check the alternator.

20. After following the above- mentioned procedures, reconnect the battery and start the car. Make sure that you will put it in idle mode.

21. Then check the voltage reading of the battery terminal between the same points again.

22. If it is placed around 10V, then the battery is in good condition. Below 10V means either the battery needs charging or other issues cause voltage decline.

24. The next phase is to check the fluid level in the battery. For doing it, you need to disconnect the battery again.

25. First open up the battery cover and peep them into the compartments of the cells inside to measure the fluid level.

26. Generally, the electrode plates are submerged in the electrolytic fluid. If they are not, then add distilled water to the cell compartment up to the fluid level.
