Identifying A Dead Battery
Signs Of A Dead Battery
If your car is struggling to start, and you notice dimming headlights or erratic electrical behavior, these are signs of a dead or dying battery. Pay attention to these indicators as they are crucial in identifying a dead battery.
Testing The Battery Voltage
To test the battery voltage, use a multimeter to measure the voltage across the battery terminals. A fully charged battery should read around 12.6 volts. Remember to conduct this test when the vehicle is turned off and has had time to rest for at least a few hours.
Common Causes Of A Dead Battery
- Leaving lights or accessories on for an extended period without the engine running
- Extreme weather conditions, which can affect battery performance
- Old age and general wear and tear on the battery
Jump-starting A Dead Battery

Items Needed For Jump-starting
- Booster cables or a jump starter pack with a charged battery
- Another vehicle with a charged battery
- Safety goggles and gloves
Step-by-step Instructions For Jump-starting
- Position the vehicles: Park the working vehicle close to the car with the dead battery, ensuring they do not touch.
- Turn off both vehicles: Make sure both cars are turned off and in park with the handbrakes engaged.
- Identify the positive and negative terminals: Locate the positive (+) and negative (-) terminals on both batteries.
- Connect the jumper cables: Attach one red clamp to the positive terminal of the dead battery and the other red clamp to the positive terminal of the working battery.
- Attach the black clamp: Connect one black clamp to the negative terminal of the working battery and the other end to an unpainted metal surface on the car with the dead battery.
- Start the working vehicle: Let it run for a few minutes to charge the dead battery.
