If your battery seems unable to charge, here are some simple checks and steps that can often quickly resolve the issue.
Rule out External Factors
Before starting to inspect the battery and charger, it's necessary to rule out some external factors that might be causing this issue.
- The outlet is faulty - you can check if the socket is functioning properly by inserting another device (such as a phone charger).
- The environmental temperature is too high or too low - like all lithium-ion batteries, electric bike batteries cannot perform optimally in extremely hot or cold conditions. The preferred temperature range for battery charging is 41°F–77°F (5°C–25°C). If your environment exceeds or falls below this range, find a location within this range and try charging again. Before inserting the charger, be sure to allow the battery some time to warm up or cool down to the new temperature.
- Charging the battery immediately after use - Some batteries that have just been used on the bike may not commence charging immediately. You can plug in the charger right away, but it might wait until the battery has cooled down slightly before initiating the charging process.
- Loose connection - Check all charger cable connections to ensure they are fully in place.
- Insufficient charging time - The battery may require up to 7-8 hours to fully charge.
- Misinterpreting the charger indicator lights' meaning - Always use the Velowave charger to charge the battery. The table below will help you correctly understand the meaning of different states of the indicator lights on the charger.
| Diagram | Indicator Light Status | Meaning |
|
Off/Blinking |
1. No power(Charger not plugged into outlet) 2. Battery failure |
|
| Green |
1. The charger is plugged into the outlet but not connected to the battery. 2. The battery is fully charged. |
|
| Red | The battery is charging. |
Assesse the battery
Verify the charge levels of the battery
Press and hold the battery button, as the figure below. Pressing the battery button will show you the charge level (Green indicates sufficient battery power, yellow indicates moderate battery power, and red indicates low battery power).
- If there is no response from the battery at all (no charge level indicators illuminate), record the process in a video, including the lights on the battery, and reach out to Customer Support for assistance.
- If the indicator light is on (green, yellow, or red), proceed with the troubleshooting process.
Check the charger
1. Plug the charger into the outlet, observe if the indicator light turns on.
- If the indicator light is not on, take a photo showing the charger plugged into the outlet and the charger indicator light. Contact our customer service for assistance.
- If the indicator light is on (green), proceed with the troubleshooting process.
2. Connect the charger to the battery (charger plugged into the outlet, indicator light is green, battery is not fully charged), and observe if the indicator light changes.
- If the indicator light remains unchanged, record the charging process in a video, including the lights on the charger and battery, and reach out to Customer Support for assistance.
- If the indicator light turns red, proceed with the troubleshooting process.
3. Measure the output voltage of the charger using a multimeter.
- If the measured voltage differs significantly from the output voltage stated on the charger's nameplate, record the charging process in a video, including the number displayed on the multimeter screen, and reach out to Customer Support for assistance.
- If the measured voltage matches the output voltage stated on the charger's nameplate (with a small allowable margin of error), your charger is good and is functioning properly.
If you have completed all the troubleshooting steps above and your battery still cannot charge or if you haven't found the issuess why it's not charging, please contact our Customer Service for further assistance.
