Tips to Extend the Lifespan of 18650 Lithium Batteries

In complex environments, frequency jammers play a crucial role in interfering with remote-controlled detonation signals. To ensure their effectiveness, frequency jammers are equipped with either built-in batteries or external battery boxes. Proper maintenance of these batteries is essential to maximize their lifespan and performance.

The Importance of Correct Charging

The most common type of battery used in frequency jammers is the 18650 lithium battery. These batteries are known for their large capacity, sufficient power, and long lifespan. To maintain the built-in battery’s effectiveness, it is crucial to use the correct charger provided with the frequency jammer. Since the batteries used in frequency jammers are custom-made, the chargers are specifically designed for these batteries.

Regular Charging and Discharging

If a frequency jammer is not used for an extended period, it is recommended to periodically charge and discharge the built-in battery. Failure to do so may result in damage to the internal 18650 lithium battery cells. If the battery is fully charged, but the frequency jammer’s usage time is significantly reduced compared to previous usage, it indicates a fault in the battery cells. In such cases, it is advisable to send the frequency jammer for repair.

Ensuring Sufficient Battery Power

After using a frequency jammer, it is crucial to promptly recharge the battery to ensure sufficient power. This will enable the frequency jammer to operate for an extended period. Regular charging and discharging are also recommended during long periods of non-use to prolong the battery’s lifespan.


In conclusion, maintaining the built-in battery or external battery box of a frequency jammer is essential for optimal performance. The use of 18650 lithium batteries, with their large capacity and long lifespan, requires proper care and maintenance. By following the correct charging procedures and regularly charging and discharging the battery, users can ensure the longevity and effectiveness of their frequency jammers.
