One of the easiest repairs on the Roadrunner is replacing the battery. The system is a slide-in/slide-out design secured by a key lock.

  1. Turn off your scooter.

  2. Unlock the battery with your key.

2. General Battery-Related Issues

Since the Roadrunner does not have a built-in voltmeter, it can be tricky to know if the battery is the problem. Here are some symptoms you might notice:

  • The LCD shows the battery draining quickly, even though the scooter still rides normally.

  • The LCD shows a full charge, but the scooter powers down suddenly.

These issues can involve not just the battery, but also the charger, battery mount, or controller. Here’s how to check them:

Step 1: Check the Charger

  • Make sure the charger light changes from red (charging) to green (fully charged).

  • Inspect the battery’s charging port for visible damage.

Step 2: Inspect the Battery Mount

The mount is what locks the battery in and connects it to the scooter.

  • Look at the red male connector at the top of the mount for any damage.

  • Check the wiring that runs into the seat (connecting to the controller) for pinches, cuts, or wear.

Step 3: Check the Controllers

It’s less common for the controllers to cause battery issues, but it can happen.

  • Look for damaged wires or water exposure.

  • If there are no obvious symptoms, the controllers are usually fine.

Step 4: Consider the Battery

If the charger, mount, and controllers all check out, the battery may need inspection.

  • Unless it’s visibly damaged (dented, swollen, or punctured), we’ll need you to send it back to our technicians for testing.

  • Once inspected, we can confirm if the battery is faulty and proceed with a replacement if necessary.
