If you own a Razor electric scooter, you may have encountered a situation where the charger light stays green even when the battery is not fully charged.
This can be frustrating and confusing, especially if you want to ride your scooter and don’t know how much battery power you have left. In this article, we will explain what causes this problem and how to fix it.
What Does the Charger Light Mean?
Most Razor electric scooters and bikes have a charger that has two lights: a red light and a green light.
The red light indicates that the battery is charging, and the green light indicates that the charger is plugged into the wall.
When the battery is fully charged, the red light turns off and only the green light remains on.
This means that the battery is ready to use and you can unplug the charger from the scooter and the wall.
Why Does the Razor Scooter Charger Light Stay Green?
There are several possible reasons why the charger light stays green when the battery is not fully charged. Here are some of them:
#1. The battery is new and has never been used
Some new batteries come with a full charge and do not need to be charged before using them for the first time. In this case, the charger light will stay green because the battery does not need any more power.
#2. The battery is worn out and needs to be replaced
Over time, batteries lose their ability to hold a charge and may become over-discharged. This means that their voltage drops below a certain level and they cannot be recharged anymore.
In this case, the charger light will stay green because the charger cannot detect any voltage from the battery pack.
#3. The charger port or the charger plug is defective
Sometimes, there may be a loose wire or a faulty connector between the battery pack and the charger port, or between the charger port and the charger plug.
This can prevent the charger from delivering power to the battery or receiving feedback from it. In this case, the charger light will stay green because there is no communication between the charger and the battery.
#4. The fuse in the charger is burned out
Some chargers have a fuse that protects them from power surges or short circuits.
If this fuse blows, the charger will stop working and will not charge the battery. In this case, the charger light will stay green because there is no power output from the charger.
How to Fix Razor Scooter Charger Green Light Problem?
Depending on what causes the problem, there are different ways to fix it. Here are some steps you can take to troubleshoot and solve it:
#1. Test the voltage output of the charger
You can use a multimeter to measure the voltage output of the charger when it is plugged into the wall. The voltage should be slightly higher than the voltage of your scooter (for example, a 24V scooter should have a 29V charger).
If the voltage is correct, then your charger and charger plug are probably good. If there is no voltage output or it is too low, then your charger or fuse may be bad and need to be repaired or replaced.
#2. Test the voltage of the battery pack at the charger port
You can also use a multimeter to measure the voltage of your battery pack when it is connected to your scooter and not charging. The voltage should be slightly higher than the voltage of your scooter (for example, a 24V scooter should have a 27V battery pack).
If the voltage is correct, then your battery pack, charger port, and wiring are probably good. If there is no voltage or it is too low, then your battery pack may be bad and need to be replaced.
#3. Test the voltage of the battery pack under load
You can also test your battery pack by turning on your scooter and engaging the throttle while measuring its voltage at the charger port.
The voltage should drop slightly but not too much (for example, a 24V scooter should have around 23V under load). If the voltage drops significantly or goes to zero, then your battery pack may be bad and need to be replaced.
#4. Check for loose wires or faulty connectors
You can also inspect your wiring and connectors for any signs of damage or corrosion.
Make sure they are securely attached and not loose or broken. If you find any problems, you can try to fix them by soldering or replacing them.
Conclusion
If your Razor scooter charger light stays green when charging, it could mean that your battery is fully charged, over-discharged, or not connected properly to the charger.
You can use a multimeter to test the voltage of your charger, battery pack, and wiring to find out the cause and fix it. If you need to replace your battery pack or charger, you can find them online or at your local scooter store.
