1. It is recommended to fully charge the product before its first use to ensure strong performance. Installation method of strong light flashlight battery: Twist open the back cover, place the battery (positive pole) towards the flashlight head, insert it into the cylinder, and twist on the back cover. The indicator light is red when charging, and when the red light turns green, it indicates that it is fully charged. Charging takes about 10 hours. To ensure the service life of the product, it is equipped with a built-in temperature control system. If the temperature is too high, it will quickly switch gears and dissipate heat, which is a normal phenomenon. Adjusting the strong and weak gears again can restore the brightness.
2. When the lighting of the product becomes significantly dim, please stop using it and charge it in a timely manner. Otherwise, when the voltage of the battery is below 2.8V, the built-in low-voltage protection function of the battery will cause the product to enter a protective state, and the light will not light up when the switch is pressed. At this time, it must be charged before use: please use the original charger when charging, otherwise it may affect the effect and even cause safety accidents due to mismatched charging parameters of the charger.
