The data may vary in real-world use due to different battery use or environmental conditions. IPX-8, 2m (Waterproof AND Submersible) Under normal charging conditions, the blue power indicator light will illuminate steadily to notify users. When charging is complete, the MH10 will terminate the charging process automatically and the blue power indicator goes out. Power Tips 1. When the light is on, the power indicator will blink once every two seconds when power level drops to 50%; the power indicator will blink quickly when power level is low. 2. After battery installation, the blue power indicator will blink to indicate battery voltage (accurate to 0.1V). For example, when battery voltage is at 4.2V, the blue power indicator will blink 4 times, followed by a one second pause and another 2 blinks. Different voltages represent the corresponding remaining battery power levels: 1 x 18650 battery 2 x CR123 batteries Low power Full power 3.5V Low power 3.7V 3.9V 4.2V Full power 4.8V 5.6V 6.0V 6.4V Changing /Charging Battery Batteries should be recharged or replaced when any of the followings occurs: The power indicator blinks rapidly, output appears to be dim or the flashlight becomes unresponsive. Maintenance Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.
