One of the most detesting feelings a person could ever experience is the one where they turn the key on their ignition only to be greeted by no sound. This is why knowing about the car battery is important since a weak car battery can leave you with your car dead at any one time.
If you do not have any tools to test your battery but you feel that it may be failing, do not panic. What about trying this from your fingertips? In this blog, we will help you run a test with your fingertips only.
In this case, we will show you how you can check your car battery at home, and you don’t need any instruments for this purpose.
6 Step By Step Guide – How to Test Your Car Battery?
One critical aspect of a car’s overall performance is making sure that the car battery is healthy. This provides an opportunity to identify problems timely, avoid emergencies, and maintain a battery’s health levels. Follow these easy steps, whether you are at home or driving your car, to check your car battery efficiently.
Step 1: Visual Inspection
First, the batteries are examined closely outside without dismantling them. Usually, visible signs, like a white or ashy substance around the terminal or around the surfaces of both terminals, must be checked. Failed cycling will affect the amount of power the battery can deliver due to corrosion.
If there is rust, one is warned to put on gloves and goggles. Then, it is advisable to rub the rust gently using a paste of baking soda and water. Clean it with a small brush or rag, and wash the surface with warm water to remove any residual chemicals.
Step 2: Check Battery Age
The durability of most auto-computer batteries lasts for an average of three to five years, and one must recognize how old the car battery is for reliability. Inspect the manufacturing date, as this information is normally written on a surface on the body of the battery, usually on the label on the cover.
If the data suggests that your battery is at the expected lifetime or slightly beyond it, it’s high time to replace it. This can help avoid failure scenarios, particularly during such weather conditions that are beyond the normal range.
Step 3: Perform a Headlight Test
A simple and reliable way to assess the health of your battery is to check the brightness of your headlights. Start your car and observe how bright the LED bulbs are. If they are dim or flickering, this may indicate that the battery is faulty and does not supply enough power.
To assess the environment even more, check the brightness of the flames after revving the engine a little. If the headlights brighten significantly with a change in RPM, then it could be possible to tackle the battery as soon as it gives its final signals.
Step 4: Try the Tapping Test
With your car engine off, gently strike the terminal with a screwdriver or some other metallic object that does not conduct electricity. Focus on the sound that the object makes. A simple thud means that the battery cells remain undamaged, and hence, they function efficiently.
On the other hand, if there is an eerie sound, then maybe there is internal damage, or the battery is about to fail. In a situation of this kind, it would be advisable to take the battery to an expert or have it changed to prevent future failures.
Step 5: Use a Multimeter (If Available)
Although only some people own testing gear specifically for cars, they have a multimeter within their reach most of the time. To check the battery voltage, ensure that the vehicle is off and then set the multimeter to the DC voltage position. Copper screws should be fitted to the battery’s positive terminals and the red lead attached to it, and the black lead connected to the negative terminal.
A good battery should read at 12.6 volts or higher if it’s fully charged to capacity. If the reading is below 12.4 volts, the battery may be only partially charged; any reading below 12.0 volts indicates that the battery is in very poor condition and may not be able to start the vehicle without charging or replacing it.
Step 6: Listen for Clicks
If you try to turn your car on, ensure you listen to the sounds it makes. One should pay particular attention to sounds like clicking. Emissions of several rapid clicks are associated with low battery power since the battery cannot generate enough power to crank the engine.
However, a single click means that there could be a problem with the starter motor or the ignition system, not the battery. In case of any of the mentioned scenarios, it is advisable to take the battery for a test and check by an experienced technician to recommend the most appropriate remedy.
Benefits of Testing Your Car Battery Regularly
- Avoid Unexpected Breakdowns: These working conditions can also be warning signs of battery problems before they spiral into failure in exigent circumstances.
- Extend Battery Life: It means that the frequency of maintenance is also tested and proportionate to the battery, which will help to increase the battery’s lifespan.
- Ensure Optimal Performance: A fine-tested battery gives good energy to the vehicle’s electrical systems and improves performance.
- Save on Repair Costs: This is because some defects that may lead to costly repairs or replacements may be detected early enough.
- Improved Safety: A dependable battery reduces the likelihood of being stuck, thus ensuring safer transport.
- Enhanced Fuel Efficiency: When in good health, batteries allow optimal functionality of the engine and thus better fuel consumption rates.
