Battery charging method: Turn on the charger first, the green light will be on; turn the battery box switch to "ON", the battery indicator light will be on; when the charger output end is connected to the battery box "DC IN/OUT", the red light will be on, and the charging starts (If the battery is fully charged and connected to the charger, the output green light will remain unchanged); because the charging circuit uses slow charging design (fast charging has an impact on battery life), the charging time is generally more than 8 hours. When the red light turns green, the battery is full-charged. Battery power supply method: Package List: 1 * Battery
