- Always follow your vehicle manufacturer's specific directions for battery installation.
- Ensure the positive (+) and negative (-) leads are connected correctly to the corresponding terminals on the battery and vehicle.
- The battery should be fitted into a vehicle that uses an adapter capable of limiting the charging voltage to less than 15 Volts.
5. Charging and Operating
5.1 Charging Procedure
It is crucial to follow these steps for safe and effective charging:
- Always remove the battery from the vehicle before charging.
- Connect the provided Advanblack charger to the battery terminals. Ensure correct polarity (red to positive, black to negative).
- Charge the battery with a lower current than the maximum charging current specified in the technical data.
- Monitor the battery during charging. If the battery becomes hot to the touch, immediately stop charging and allow it to cool completely before resuming.
- After charging is complete, leave the battery for 1 to 2 hours before checking its voltage or Cold Cranking Amps (CCA). If the voltage is still less than 12.4 Volts, additional charging may be necessary.

7. Troubleshooting
If you encounter issues with your Advanblack Powerbox LIB45 battery, consider the following:
- Battery Not Starting in Cold Weather: Lithium batteries can experience reduced performance in very cold temperatures (below 35°F / 2°C). If your motorcycle struggles to start, try warming the battery slightly before attempting to start, or ensure it is fully charged.
- Battery Voltage Below 12.4V: If a voltmeter indicates the battery voltage is below 12.4V, perform a refresh charge using the provided charger.
- Battery Becomes Hot During Charging: Immediately disconnect the charger and allow the battery to cool down completely before attempting to charge again. If the issue persists, discontinue use and contact customer support.
- No Power Output: Check all connections to ensure they are secure and correctly polarized. Verify the battery voltage. If voltage is extremely low (below 9.5V), the battery may be over-discharged and require professional assessment.
