Car batteries have an average life of 3 to 5 years, and when it’s time for a replacement, it’s important to dispose of the old one safely. If you have a new battery installed at a shop, they’ll typically take care of the disposal for you. But if you handle it yourself, you can use our tips and resources to help ensure your safety.[1]
How to remove a car battery
Before you start the battery removal process, ensure that the ignition is off, and wear gloves and safety goggles to protect yourself while performing the work.[2]
Remove the terminal connectors: The negative terminal is black and typically will be marked with a “-” symbol; it may also have a black plastic cap. Remove the cap if needed, then use a wrench to turn the nut counterclockwise until you can remove the cable from the battery. Ensure that the cable is fully disconnected and moved away from the battery. Repeat these steps for the positive terminal. The positive terminal and cap (if applicable) will be red and have a “+” symbol.[2]
Remove the battery: Most batteries are secured with a clamp. Detach the nuts with a socket wrench, remove the clamp and lift the battery.[2]
How to store car batteries
After the battery is removed, safe storage is essential if you can’t dispose of it immediately.
- Store the car battery indoors, if possible, away from weather and extreme temperatures
- Store the car battery away from other kinds of batteries
- Keep the battery upright on a nonreactive, impermeable surface
- Don’t place anything metal on the battery
- Avoid flames, sparks and smoking near the battery[3]

Responsibly disposing of a car battery is important for health, safety and environmental reasons. When you hit the road with your new battery, be sure you’re covered with auto insurance.
