5. Troubleshooting
5.1 Power Leakage / Self-Discharge
If the battery experiences significant power loss when not in use, ensure that Low-Current Mode is properly exited. If the issue persists, try resetting the battery by repeatedly pressing the power button (more than 10 times quickly) or holding it for approximately 20 seconds. If the problem continues, contact customer support.
5.2 Slow Charging
For optimal charging speed, use a PD protocol charger and connect it to the USB-C1 port. Ensure the charger provides sufficient wattage (e.g., 140W) to achieve the advertised 2-hour full charge time. When charging via D-TAP, ensure voltage does not exceed 16.8V and current stays below 8A to protect the battery.
