The battery indicator helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. The MK37 Luminus cannot charge batteries directly. You may need an external charger to keep your battery going. When the flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output.

The MK37 Luminus has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. The "8" in the IPx8 rating indicates the highest level of protection against water ingress. The impact resistance of a flashlight can vary depending on its design, construction, and intended use.
