You're not alone if you're using a MUKUTA battery and facing performance problems. Many riders have experienced issues such as charging but not turning on, charging failure, short battery life, and even sudden power outages.
In this blog post, we'll walk you through common MUKUTA battery problems and practical solutions to help you resolve them.
Why is My E-Scooter Battery Not Charging?
An e-scooter battery doesn’t charge due to two reasons.
First, the battery has a defective charger, wire, or charger port, preventing it from charging fully.
Second, the battery is over-discharged and has reached a low level that prevents it from recharging. It happens if a battery drains or doesn't recharge for a long time after storing it with a full charge.
Why Can't My E-Scooter Start Even Though the Battery is Fully Charged?
If your electric scooter doesn't turn on, you should make a few preliminary checks before moving on to more complicated troubleshooting. Here are some basic steps you can take to diagnose the problem:
# Inspect the Charger and Connections
Sometimes, a loose wire or damaged connection stops the scooter from turning on. Confirm that the charging port is intact and that the charger is fitting snugly without any signs of damage. It's crucial to check the battery charger thoroughly, ensuring it's properly connected to both the scooter and the power outlet.
If you observe any wear or defects, this might be why your scooter won't turn on. To test your electric scooter's charger functionality, consider using a multimeter to verify its output voltage.
Additionally, while checking connections, it's also a good idea to examine the motor and its connections, as issues there could also prevent the scooter from powering up.
# Examine the Fuse or Circuit Breaker
If the battery is all charged up and the charger and wires are looking good, you might need to take a peek at the fuse and circuit breaker. When your electric scooter won't turn on, it's smart to check the fuse or circuit. If the fuse looks burned out or the circuit breaker has popped out, that could be the trouble.
To be sure, you can use a voltmeter to see if there's an open circuit. Make it safe by turning off your electric scooter before you start. Scooters equipped with a circuit breaker might have it trip sometimes, and the best way to fix that is to press reset to get things back to normal. This could get your scooter ready to go once more.
If either of these is the case, you will need to replace the fuse or reset the circuit breaker before attempting to turn on the scooter again.
Troubleshooting Common Issues
# Battery and Power Issues
You need to check if the scooter charger or battery is broken. Here are the steps to check:
Troubleshooting Charger Failure
1. The scooter is dead, but the charger keeps the green light, at this time we think that the charger or the battery may be faulty.
2. First we troubleshoot the charger and measure the charger voltage (1+ and 3-). Adjust the voltmeter to DC200 level for measurement.
3. For example, the normal voltage value of the charger for a 60V scooter is 67.2V, and the normal voltage value of the charging for a 48V scooter is 54.6V. ±0.3 deviation is normal, and if it is lower or higher than this value, it means that there is a problem with the charger, and you need to replace it with a new one.
Troubleshooting Battery Failure
If the charger is normal, but the scooter still does not work properly, you need to troubleshoot the battery:
1. Measure the battery voltage, and measure the battery discharge port and charging port (the voltmeter is adjusted to DC200 level for measurement).
2. If the voltage is the same, then it is normal, otherwise it means the battery has problems. The voltage of the charging port and discharging port should be the same, take 60V 10plus as an example, the value should be 49-67.2V, 48V 9plus value should be 39-54.6V.

# Controller or Motor Malfunctions
If your battery and power supply are in good shape but your scooter has trouble starting or doesn't run well, the problem might be with the motor or controller.
Sometimes, if the motor still doesn't work after you check it, the power voltage could be a common reason for this trouble. It's a good idea to look at the motor or controller for any clear damage or signs that they are old or used too much.
If you see something wrong, you might have to get a new motor or controller. But before you do that, you can try to fix the issue by turning off the scooter and waiting for a few seconds before turning it back on.
This can sometimes reset the system. If your electric scooter keeps having problems, it might be time to look closer at the motor issue.
If you notice more issues, you may need to replace the motor or controller.
# Throttle and Display Issues
The throttle is an essential component of your electric scooter. If the throttle is not working correctly, the scooter won't turn on. Check the throttle connection and make sure it is securely connected to the controller. Ensure there are no loose or damaged wires.
If your display is not working correctly, it can also prevent your scooter from turning on. Check the display connection and make sure it is securely connected to the controller. If the display is damaged, it may need replacing.
# Resetting Your Electric Scooter
Sometimes, a simple reset can fix the problem. Turn off the scooter, disconnect the battery, wait for a few minutes, and then reconnect the battery. This process can help reset the system and fix any minor issues that may be preventing your scooter from turning on.
Troubleshooting Your Electric Scooter Charger: A Step-by-Step Guide
When you suspect that your scooter's charger may be malfunctioning, a quick and thorough test can save you time and frustration. In this guide, we'll walk you through the necessary steps to test your electric scooter charger. In this guide, we'll walk you through the necessary steps to test your electric scooter charger effectively, so you can get back on the road in no time.
# Step 1: Inspect the Charger for Physical Damage
Begin by visually inspecting the charger for any obvious signs of damage, such as frayed cables, bent plugs, or burn marks. These physical clues often indicate that the charger may be defective or damaged and could require replacement.
# Step 2: Check the Power Outlet
Before testing the charger itself, confirm that the power outlet you're using functions correctly by plugging it into another device. This can help rule out the possibility that the issue lies with your power supply rather than the charger.
# Step 3: Verify the Connection
Connect your charger to both the scooter and the power outlet. Ensure all connections are secure and the charger is fully plugged in. A loose connection can sometimes be the culprit behind charging issues.
# Step 4: Read the Indicator Lights
Most electric scooter chargers Most electric scooter chargers come with an LED indicator light that shows the charging status. A solid or blinking green light typically indicates a good connection and that the battery is either charging or fully charged. A red light could indicate that the battery is actively charging. If the light doesn't come on at all, this may suggest a fault in the charger.
# Step 5: Use a Multimeter
If the charger's indicator lights do not reflect the normal charging behavior, use a multimeter to test the output voltage. Set the multimeter to DC voltage, and carefully place the probes on the charger's output plug. You should see a reading that matches the charger's rated output voltage. If the voltage is significantly lower or no voltage is detected, the charger may need to be replaced.
# Step 6: Try a Different Charger
If available, use a charger that you know is functioning to see if the scooter charges appropriately. This can help confirm whether the issue is indeed with the charger or possibly with the scooter's battery or internal electronics.
