To determine if your car battery is dead or just discharged, here are a few signs and checks you can perform: To determine if your car battery is dead or just discharged, here are a few signs and checks you can perform:
- Dim Lights: The battery may be drained if the instruments are not sufficiently illuminated or the headlights are faint in the evening. If they are way off, then it might be dead altogether.
- No Crank or Slow Crank: If you hear a slow cranking sound, then the battery is probably low on charge, whereas if the engine does not crank at all, then it would be safe to conclude that the battery is dead.
- Clicking Sound: If there is a fast clicking sound, as soon as the key is turned, besides the key, then the battery can still voltage, but it is not enough to start the engine.
- Check the Voltage: Use a multimeter to check the voltage of a battery. A good battery should be at about 12 volts full charge; below 12 volts will be a low charge. 6 volts. If it’s much lower (for instance, below 12 volts), then it might just be that the battery is flat. If it is a lot lower, it could be dead or a damaged power source.
- Jump Start: First, attempt to turn the car engine. The battery could have only drained if it had started and kept running. If it does not hold the charge after being run, it will be good to replace it.
- Corrosion or Lose Connections: Look for signs of corrosion around the battery terminal and loose connections that may interfere with the battery’s charging. Cleaning and securing these may solve this problem.

Quick and Easy Battery Diagnosis Tips

- Listen for Clicking Sounds: A weak battery might cause clicking noises when starting the car.
- Dim Headlights: If the headlights are dim when the engine is off, it could mean a weak battery.
- Slow Engine Crank: If the engine takes longer than usual to start, your battery might be low.
- Battery Warning Light: If the battery icon on your dashboard lights up, it’s time to get the battery checked.
How to Easily Perform a Car Battery Test at Home
To test your car battery at home, begin by turning off your car and determining the bonnet’s openness. Switch the multimeter to the DC voltage (20V) and place the red probe on the positive terminal while the black is on the negative terminal. The battery should sit at around 12 V for a healthy battery or 6 volts. Start the car and check the voltage one more time. It must be 13 V or a bit more, 7 and 14. 7 volts.
If the above readings are low, it might indicate that the battery or the alternator is failing due to oxidation, cracks, or any other signs of damage. If in doubt, seek professional help to have a proper examination done.
