Common Causes of Dead Battery Problems
A dead battery isn’t always a sign of a faulty battery. Several factors can contribute to this issue:
- Leaving lights on: This is a classic culprit. Even interior lights can drain your battery overnight.
- Extreme temperatures: Both extreme heat and cold can significantly impact battery performance and lifespan.
- Old age: Batteries have a limited lifespan, typically 3-5 years. As they age, their ability to hold a charge diminishes.
- Corroded terminals: Corrosion on the battery terminals can disrupt the flow of electricity.
- Parasitic drain: This occurs when an electrical component continues to draw power even when the car is off. If you think your car suffers from this, check our guide on battery is good but car keeps dying.
- Faulty alternator: A malfunctioning alternator won’t recharge the battery while the engine is running, eventually leading to a dead battery. Read more on how to diagnose if it’s your dead alternator or battery.

- Position the vehicles: Park the vehicles close enough for the jumper cables to reach, but ensure they don’t touch.
- Connect the red (positive) cable: Attach one end to the positive terminal of the dead battery and the other to the positive terminal of the working battery.
- Connect the black (negative) cable: Attach one end to the negative terminal of the working battery and the other to a clean, 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.
- Start the vehicle with the dead battery: If it starts, disconnect the cables in the reverse order of connection.
- Keep the engine running: Drive for at least 30 minutes to allow the alternator to recharge the battery. If you have a new battery and it’s already dead, find out why at new battery already dead.
Preventing Dead Battery Problems
