What should you do if your car battery dies?

If your car battery dies, here is the safest and most effective way to handle it:

1. Assess the situation Ensure your car is in a safe location, away from moving traffic. Turn on your hazard lights. If you are in a dangerous spot, stay inside the vehicle and call for roadside assistance.

2. Determine the cause Check if you accidentally left your headlights or an interior light on. If you did, your battery likely just needs a jump-start. If the battery is old (typically 3–5 years) or the terminals are corroded, it may need to be replaced.

3. Jump-start the car If you have jumper cables and another vehicle, you can jump-start your battery:

• Connect the red (+) cable to the positive terminal of the dead battery.
• Connect the other red (+) end to the positive terminal of the working battery.
• Connect the black (–) cable to the negative terminal of the working battery.
• Connect the other black (–) end to an unpainted metal surface on the engine block of the dead car (not the negative terminal of the dead battery to avoid sparks).
• Start the working car, let it run for a minute, then try to start your car.
• Once started, remove the cables in the exact reverse order.

4. Keep the engine running Drive your car for at least 20–30 minutes, preferably at highway speeds, to allow your alternator to recharge the battery.

5. Get it checked Even if the car starts again, a dead battery can be a sign that it is reaching the end of its life or that your alternator is not charging it properly. Visit an auto parts store or a mechanic to have the battery and charging system tested.

If you are unsure or uncomfortable performing a jump-start, call a professional. Many insurance policies include roadside assistance, and services like AAA or local towing companies can help you safely.
