Maintenance of Internal Battery and External Battery Box for Police Jammer

In order to ensure that the police jammer can effectively interfere with remote detonation signals in different locations, and to address the issue of outdoor mission equipment lacking 220V AC power supply, bomb disposal jammers are equipped with built-in batteries or external battery boxes. Whether using a built-in battery or an external battery box, there are many considerations for maintaining the internal battery of the police jammer when it is idle.

In this article, we will discuss how to maintain the internal battery and external battery box of a police jammer.

Choosing the Right Charger:

Regardless of whether the police jammer uses a built-in battery or an external battery box, the mainstream batteries and battery boxes currently available in the market typically utilize 18650 lithium batteries as the basic cells. These batteries are known for their large capacity, sufficient power, and long lifespan. However, in order to maximize the performance of the internal battery of the police jammer, it is crucial to use the correct charger for charging. Since bomb disposal jammers usually use customized batteries, the charger should also be specifically designed for these batteries.

Regular Charging and Discharging:

If the bomb disposal jammer is not used for a long period of time, it is recommended to perform a charging and discharging cycle on the internal battery of the police jammer at regular intervals. This helps to maintain the battery’s performance and prolong its lifespan. Charging and discharging the battery once every few months can prevent the battery from becoming overcharged or completely discharged, which can lead to capacity degradation.

Proper Storage:

When the police jammer is not in use, it is important to store it in a cool and dry place. Extreme temperatures, both hot and cold, can negatively impact the performance and lifespan of the internal battery. Additionally, it is advisable to remove the battery from the jammer if it will not be used for an extended period of time. This prevents any potential damage caused by leakage or corrosion.


The maintenance of the internal battery and external battery box of a police jammer is crucial for ensuring its optimal performance and longevity. By using the correct charger, regularly charging and discharging the battery, and storing it properly, the internal battery of the police jammer can be effectively maintained. This allows the jammer to function at its maximum capacity when needed, providing reliable interference against remote detonation signals.
