5. Operating Instructions

1. Charging Indication: Once connected to a power source and batteries are correctly inserted, indicator lights on the charger will illuminate to show the charging status. Refer to the charger's specific light behavior for full/charging status (e.g., red for charging, green for fully charged, or off when not charging).
2. Charging Time: Charging time varies depending on the battery capacity (mAh) and the power output of your USB source. Higher capacity batteries will take longer to charge.
3. Completion: When batteries are fully charged, the indicator lights will change (if applicable) or you can remove them after the estimated charging time. It is generally recommended to remove batteries once fully charged to prevent overcharging, although many modern chargers have built-in protection.
