Can you jump a motorcycle battery with a car battery？

Step-by-Step Guide:

1. Turn off both vehicles.
   Ensure both the motorcycle and car are completely off before connecting the cables.

2. Connect jumper cables in this order:

   • Red clamp to motorcycle battery positive (+)

   • Red clamp to car battery positive (+)

   • Black clamp to car battery negative (–)

   • Black clamp to a metal part on the motorcycle frame (ground), not the battery

3. Start the motorcycle.
   Try starting the motorcycle without starting the car. Most of the time, the car battery’s charge is enough.

4. If needed, start the car.
   Only if the motorcycle doesn't start after a few tries, briefly start the car to give more power — but limit this to a few seconds.

5. Remove the cables in reverse order once the motorcycle starts:

   • Black from motorcycle frame

   • Black from car battery

   • Red from car battery

   • Red from motorcycle battery

6. Keep the motorcycle running for at least 15–30 minutes or go for a ride to recharge the battery.

 Important Tips:

• Do NOT leave the car running too long. Car batteries can overpower motorcycle systems because they typically provide more amperage.

• Make sure both systems are 12V. Never jump a 6V motorcycle with a 12V car battery.

• If you're unsure, use a portable jump starter designed for motorcycles — it's safer.
