Charging Methods
1. Internal Battery Charging: Some metal detectors have built-in rechargeable batteries that can be charged using a dedicated charger. Connect the charger to the battery to begin charging. Charging time is generally 3-5 hours; refer to the battery manual for specific instructions.
2. External Charging: If the metal detector uses ordinary dry-cell batteries, it can be charged using a charger or rechargeable batteries. Before charging, remove the dry-cell batteries, connect the charger to the rechargeable batteries, and then plug the charger into a power source. After charging is complete, insert the batteries back into the metal detector.
Precautions
1. It is recommended to use the original manufacturer's charger or a charger from a reliable brand to ensure charging quality and safety.
2. Follow the charging time and method in the battery manual; do not deviate from these instructions.
3. When charging, confirm the battery polarity to ensure correct connection between the charger and battery. Failure to do so may damage the battery or malfunction the charger.
4. When charging, turn off the metal detector and charge in a well-ventilated environment to avoid accidents.
5. Do not overcharge or leave the charger and battery unattended for extended periods, as this may affect battery life and performance.
