In order to shield the signal of remote detonating, the carrier type Signal Jammer can play its role in different places. At the same time, in order to solve the power supply problem of outdoor task equipment, it will be equipped with built-in battery or external battery box. Whether the built-in battery or the external battery box is idle, it is necessary to maintain the internal battery。

No matter whether the signal jammer is a built-in battery or an external battery box, the current mainstream batteries and battery boxes will choose 18650 lithium battery as the basic cell of the battery. 18650 cell has the characteristics of large capacity, sufficient power and long service life. Only by properly maintaining the battery can the built-in battery of box shielded mobile phone signal play the greatest role

Charge with the correct charger. The batteries used by the signal jammer are basically customized batteries, so the battery charger is also specially customized and matched according to the customized battery, so the charging of the built-in battery should also be equipped with a special charger.

If the equipment is not used for a long time, the battery of the Signal Jammer shall be charged and discharged at intervals. If the built-in battery of the equipment is not charged in time, the internal 18650 lithium battery cell may be damaged. If it occurs, after the battery is fully charged, the Signal Jammer will be used for a period of time, but this time does not reach the normal use time. Then, after shutting down and waiting for a period of time, turn on the equipment again, and the equipment can operate for a period of time. At this time, it can be basically determined that the 18650 lithium battery cell shielding the mobile phone signal is faulty, It needs to be returned to the factory for repair.
