Battery box with charger and status display
 JetLock can be filled with traditional disposable batteries. In this case, the battery box of the unlocked JetLock has to be opened and pulled out. Alternatively, JetLock can be equipped with rechargeable batteries. The battery box can be connected to suitable battery charger. Normally, JetLock only needs very little energy thanks to its LED-technology. Nevertheless, the status display should be checked from time to time and if necessary the battery should be changed or recharged so that there is always enough power for the alarm.
