The power source of the PT40 LH351D flashlight is 1 x 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. The PT40 LH351D 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 thermal protection feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The IPx6 rating indicates that the flashlight has a protection against water jets. The impact resistance of a flashlight refers to its ability to withstand physical shocks or impacts without being damaged. The PT40 LH351D is magnetic so that the flashlight can be attached to some metallic surfaces.
