Charging your Milwaukee L4HL2301 Redlithium USB Hard Hat Headlamp is straightforward. Here's how to do it: First, connect your USB cable to a power source. This could be an AC wall adapter, a computer, or even your car's USB port. Next, locate the USB Type C port on your headlamp. It's usually hidden behind a rubber cover; lift the cover to access it. Now, plug the USB Type C connector into the port on the headlamp. Keep in mind that charging times may vary depending on your power source. For example, charging via a laptop might take longer. The headlamp's indicator light will show the charging status: A pulsing red light indicates charging and that the is between 0-49% charged. A pulsing yellow light means the headlamp is charging, and the battery is between 50-99% charged. A solid green light shows that the headlamp is fully charged (100%). If the indicator flashes red and green, it could mean there's an issue. Ensure the battery is properly seated. If the problem continues, and the battery is extremely hot, cold, or wet, allow it to adjust to room temperature and dry out before attempting to charge again. If the issue persists, contact a MILWAUKEE service facility for support.
