Step-by-Step Guide How to Jump a Motorcycle Battery Using Another Motorcycle
Jumpstarting a motorcycle battery using another motorcycle is the most effective way. The most efficient way to jumpstart a motorcycle battery is to use another motorcycle. However, using another motorcycle still involves risks that could harm the battery and the motorcycle’s electrical system. Therefore, here is a guide on how to jump a motorcycle battery using another motorcycle safely and effectively.
Step 1: Position the Motorcycles
Ensure that both motorcycles are positioned in a stable and standing close to one another, this will make accessing the batteries easier. Use a motorcycle stand to ensure that neither of the motorcycles will fall over during the jump start process.
Step 2: Turn OFF Both Motorcycles
Ensure that neither of the motors are running and that electrical accessories are turned off on both motorcycles in order to prevent a current surge.
Step 3: Identify the Battery Terminals
Take off the battery cover and look for the positive and negative battery terminals. There’s a chance that you could connect the wires to the wrong battery terminals. The battery terminals do have markings that indicate if they’re positive or negative. Red or (+) is positive, and black or (-) is negative.
Step 4: Attach the Jumper Cables to Each Terminal
When putting on the jumper cables, ensure to do it in the correct order, starting with the discharged battery, then to the healthy battery. Then, for the order of plugs, ensure to do the red one first to positive terminal, then the black one (negative) to the motorcycle’s frame then the healthy battery. Ensure the connection is firm and secure.
Step 5: Start the Donor Motorcycle
When everything is checked and stable, start the donor motorcycle to begin the transfer of charge to the discharged battery and wait for 1 to 2 minutes.
Step 6: Turn ON the Motorcycle with Low Battery
Try starting the motorcycle with a low battery to see if the jumpstart process is successful in restoring battery power. If it doesn’t start, then wait for about 30-60 minutes and then try to restart it–avoid pressing the starter for too long to prevent system damage.
Step 7: Disconnect Jumper Cables Sequentially
Once the motorcycle has successfully started, ensure that you disconnect the jumper cables in the reverse order–i.e. negative first from the weak battery and then the healthy battery, then disconnect the positive cable from the healthy battery terminal and then disconnect it from the motorcycle ground. Leave the motorcycle running for 5-10 minutes to allow the motorcycle’s charging system to work on recharging the previously depleted motorcycle.
Step-by-Step Guide How to Jump a Motorcycle Battery Using a Portable Jump Starter
Jumpstarting a motorcycle using a portable jump starter is a practical solution to starting a discharged motorcycle battery without requiring other vehicles’ assistance. Although this tool is very practical to use, the usage procedure must still be done correctly to prevent the electrical system or battery from being permanently damaged. Here’s a guide on how to jump a motorcycle battery using a jump starter.
Step 1: Ensure the Portable Jump Starter is in Ready-to-Use Condition
Check the portable jump starter condition first–whether there’s enough charge left in the battery and the wiring is in good condition. Some jump starters also have indicator lights to confirm power readiness.
Step 2: Turn OFF the Motorcycle's Engine and Contacts
Before connecting the tool to the weak motorcycle battery, ensure that the motorcycle’s engine is completely shut off to prevent potential power surges.
Step 3: Access and Identify the Motorcycle Battery Terminals
Open the battery cover and identify which one is the positive (+) terminal and which one is the negative (-) terminal.
Step 4: Connect the Jump Starter Cables
Once the terminals have been identified, start connecting the positive (red) jump starter cable to the battery’s positive terminal first. Then, continue connecting the negative (black) cable to the battery negative terminal or the motorcycle frame. This sequence helps you avoid sparks due to polarity errors.
Step 5: Activate Portable Jump Starter
Turn ON the tool and activate the jumpstart mode according to the manufacturer’s instructions. Sometimes, some jump starters activate immediately when both cables are plugged in.
Step 6: Start the Motorcycle
Try to start the motorcycle to see if the battery power has returned. If it doesn’t turn on, try to do it again after waiting for about 30-60 seconds.
Step 7: Turn OFF and Disconnect Jump Starter
When the motorcycle has successfully started, turn off the portable jump starter by disconnecting the negative cable first then the positive. Afterward, leave the motorcycle running for a few minutes to recharge the battery.
Common Mistakes to Avoid
Although the jumpstarting process may seem simple, a small mistake won’t only cause the jumpstarting process to fail, but also potentially damage the battery, electrical system, and endanger the rider. Therefore, before jumpstarting, you should familiarize yourself with the following common mistakes to avoid.
- Connecting the Wrong Battery Polarity: Incorrectly connecting the battery–such as the positive cable to the negative terminal–will cause potential short circuits, sparks, and damage to the motorcycle’s electrical components.
- Starting the Engine Before the Cables are Properly Installed: This mistake will lead to sparking or unstable electricity flow.
