Check the Charger
- Ensure the charger is plugged into a working outlet. Test the outlet with another device to confirm.
- Inspect the charger for any visible damage, such as frayed wires or a broken plug.
- Try using a different charger if possible, as the charger itself may be faulty.
Inspect the Battery Connection
- Turn off the Tern bike and remove the battery carefully following the manufacturer's instructions.
- Clean the contacts on the battery and the bike with a dry cloth to remove dirt or corrosion.
- Reattach the battery, ensuring it's properly seated and locked into place.
Check for Software Updates
- Visit the Tern website or contact their customer support to see if there are any software updates available for your bike model.
- Follow the instructions provided by Tern to update the software, if necessary.
Test the Battery
- If possible, test your battery in another compatible Tern bike to see if it charges.
- Alternatively, test another battery in your Tern bike to determine if the issue is with the bike or the battery.
Temperature Considerations
- Make sure the charging environment is not too hot or cold. Optimal charging temperatures are typically between 10°C to 35°C (50°F to 95°F).
- If the battery feels very hot, let it cool down before attempting to charge again.
Consult a Professional
- If none of the above steps resolve the issue, contact Tern customer support or a certified repair professional for further assistance.
- Provide details about the issue and any troubleshooting steps you have already taken.
