Make sure the plastic films on the batteries were removed before using. 2. Charge all the batteries fully before using, otherwise, it can only last a pretty short time, and then shut off, under which condition, the batteries could be over-discharged as this is a high power headlamp, which needs more power to drive than normal headlamp. 3. Re-charge the batteries in time when it's of low power to prevent over-discharge, which can lead batteries dead. 4. Use adapter to charge the batteries that is with an output of 5V-1A, which can get them fully charged more quickly. 5. Take out all the batteries if you don't use the headlamp for a long time. 6. Since the light got circuit protection function, it won't work if battery's negative and positive side is placed incorrectly, so do pay attention to the pole of each battery when placing.
