What Causes a Dud Battery?
Several factors can contribute to a dead battery. Leaving your headlights on overnight is a classic culprit.

Diagnosing a Dud Battery
How can you tell if your battery is truly dead? Several signs point to a dud battery. The most obvious is the engine not cranking or turning over at all. Dim headlights, especially at idle, can also indicate a weak battery. A clicking sound when you turn the key often means the battery has enough power to engage the starter solenoid but not enough to crank the engine.
Testing Your Battery
You can test your battery’s voltage using a multimeter. A fully charged battery should read around 12.6 volts. A reading below 12.4 volts usually indicates a low charge. You might also consider a battery load tester for a more accurate diagnosis.
Jump-Starting Your Car
Jump-starting can be a temporary solution to get your car running if you have a dead battery. However, it’s essential to do it correctly to avoid damaging your car’s electrical system. First, connect the positive (red) cable to the positive terminal of your dead battery. Then, connect the other end of the positive cable to the positive terminal of the good battery. Next, connect the negative (black) cable to the negative terminal of the good battery and the other end to a metal ground on your car, away from the battery. Start the car with the good battery and let it run for a few minutes. Then, try starting your car.
