• Regular charging: When the battery is not used for a long time (more than 15 days), it is recommended to charge it to 50%-70% of its capacity before storage. Charge it once every 1-2 months to prevent the battery from being over-discharged and damaged.
• Charging operation: Install the battery correctly into the charger, then connect to the power socket. When the charging indicator light turns red, it indicates that the battery is charging. When it turns green, it means the charging is complete. Disconnect the power supply in time.
• Storage environment: Store it in a dry, ventilated, and cool place, away from fire sources, heat sources, water sources, corrosive substances, and direct sunlight or heavy pressure.
• Longer battery life: Avoid frequent deep discharging (recharging after the battery runs out of power). Charge it promptly when there is about 20% of remaining power during daily use, which can extend the battery's cycle life.
