5. Operating: Charging and Usage
5.1. Charging the Battery
Before first use, fully charge the battery. Regular charging helps maintain battery health.
- Connect Charger: Plug the charger into a standard wall outlet. Then, connect the charger's output plug to the charging port on the K5 battery. The charging port is typically located near the lock mechanism (refer to Figure 4.1).
- Monitor Charging Indicator: The charger will have an indicator light (usually red for charging, green for fully charged). Refer to your charger's manual for specific indicator meanings.
- Full Charge: Allow the battery to charge until the indicator light shows a full charge. This typically takes several hours. Do not overcharge the battery by leaving it connected for extended periods after it's full.
- Disconnect: Once fully charged, disconnect the charger from the battery first, then from the wall outlet.
5.2. Battery Usage
- Ensure the battery is securely locked into the scooter before riding.
- Monitor the battery level indicator on your scooter's display during operation.
- Avoid completely draining the battery. It is recommended to recharge before the battery level drops below 20%.
- If the scooter will not be used for an extended period, charge the battery to approximately 50-60% before storage.
6. Maintenance
- Cleaning: Wipe the battery exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Ensure charging ports and contacts are clean and free of debris.
- Storage: When storing the scooter or battery for extended periods, keep the battery charged to approximately 50-60%. Store in a cool, dry place, away from direct sunlight and extreme temperatures. Recharge every 1-2 months to prevent deep discharge.
- Inspection: Periodically inspect the battery casing for any signs of damage, swelling, or leaks. If any damage is observed, discontinue use immediately and contact support.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging. | Charger not connected properly; faulty charger; damaged battery; power outlet issue. | Ensure charger is securely plugged into both the wall and battery. Test the outlet with another device. Try a different compatible charger if available. If problem persists, contact support. |
| Scooter not powering on with battery installed. | Battery not fully charged; battery not securely installed; loose connections; faulty battery. | Ensure battery is fully charged and securely locked in place. Check all connections. If the issue continues, the battery or scooter may require service. |
| Reduced range or short battery life. | Battery degradation over time; improper charging habits; extreme operating temperatures. | Ensure proper charging practices (avoid deep discharge, don't overcharge).
