Understanding the color codes on your car battery is crucial for jump-starting it safely and effectively. The question “Which color is positive on a car battery?” is a common one, and for good reason! Knowing the answer can prevent damage to your vehicle and even keep you safe.
Let’s clear up any confusion:
The positive terminal on a car battery is always red, while the negative terminal is black.
This color coding is a universal standard in the automotive industry, ensuring consistency and safety.
Why is Knowing the Positive Terminal Important?
Connecting jumper cables incorrectly can have serious consequences. Reversing the polarity (connecting positive to negative and vice versa) can lead to:
- Damage to your car’s electrical system: This can range from blown fuses to damage to sensitive electronic components, leading to expensive repairs.
- Battery explosion: While rare, an incorrect jump-start can cause a battery to explode, posing a significant risk of injury from battery acid and debris.
- Fire hazard: Incorrect connections can generate sparks and heat, potentially igniting flammable materials near the battery.

How to Identify the Positive and Negative Terminals
Here’s how to correctly identify the positive and negative terminals on your car battery:
- Look for the color: As mentioned, the positive terminal is red, and the negative is black.
- Check for symbols: The terminals are also marked with “+” for positive and “-” for negative.
- Consult your owner’s manual: If you’re unsure, your car’s owner’s manual will have a diagram showing the battery and its terminals.
Jump-Starting a Car Safely
Knowing the positive and negative terminals is only the first step in safe jump-starting. Always follow these safety precautions:
- Wear safety glasses and gloves to protect yourself from battery acid and potential sparks.
- Ensure both cars are turned off before making any connections.
- Connect the positive (red) cable first, then the negative (black) cable.
- Attach the negative (black) cable to a metal grounding point on the dead car’s frame, not directly to the negative battery terminal.
- Disconnect the cables in reverse order after jump-starting.

In Conclusion
Remembering that the red terminal is positive on a car battery is essential for safe jump-starting and avoiding potential hazards. Always prioritize safety and follow the correct procedures when dealing with your car’s electrical system.
If you have any doubts or are uncomfortable performing a jump-start yourself, it’s always best to contact a qualified mechanic or roadside assistance service.
FAQ
1. Can I use any jumper cables?
It’s crucial to use jumper cables with a gauge (thickness) appropriate for your vehicle’s battery. Using cables that are too thin can be ineffective or even dangerous.
2. What if my battery terminals are corroded?
Clean corroded terminals with a baking soda and water solution and a wire brush before connecting jumper cables.
3. How long should I charge a dead battery with jumper cables?
Allow the dead battery to charge for a few minutes after connecting the jumper cables before attempting to start the vehicle.
4. My car battery keeps dying. What could be the problem?
A recurring dead battery can indicate a problem with your car’s charging system, such as a faulty alternator or a parasitic drain on the battery. Consult a mechanic for diagnosis and repair.
