How to jump start a motorcycle battery？

What You Need:

• Jumper cables

• A 12V power source, such as:

  • Another motorcycle with a good battery

  • A car (engine off!)

  • A portable jump starter

 Safety Tips:

• Make sure both vehicles are off before connecting the cables.

• Never start a car engine while jump starting a motorcycle—it could overload the motorcycle’s system.

• Ensure the jumper cables don’t touch each other once connected.

 How to Jump Start a Motorcycle:

Step 1: Locate the Batteries

• Find the battery on your motorcycle (often under the seat).

• Do the same on the donor vehicle or jump starter.

Step 2: Connect the Jumper Cables

1. Red to Dead: Connect red (+) clamp to the positive terminal of the dead battery.

2. Red to Donor: Connect the other red (+) clamp to the positive terminal of the good battery.

3. Black to Donor: Connect black (–) clamp to the negative terminal of the good battery.

4. Black to Frame: Connect the other black (–) clamp to a metal part of your motorcycle’s frame, away from the battery and fuel system (acts as a ground).

Step 3: Start the Motorcycle

• Wait a few seconds, then try to start the motorcycle.

• If it doesn't start after a few tries, wait a minute or two before trying again.

Step 4: Disconnect the Cables (in reverse order)

1. Black clamp from motorcycle frame

2. Black clamp from donor battery

3. Red clamp from donor battery

4. Red clamp from motorcycle battery

Step 5: Keep It Running

• Let the motorcycle idle for at least 15–20 minutes or take a short ride to help recharge the battery.

 Alternative: Push Start (for manual bikes)

If you don’t have jumper cables:

1. Turn on ignition and put the bike in 2nd gear.

2. Hold in the clutch and push or roll downhill until you reach 5–10 mph (8–16 km/h).

3. Quickly release the clutch while giving the throttle a twist.

4. The engine should crank and start.
