In this video, we will talk about the indicator lights on the battery pack and what it means if it is flashing for different times. The test model is our K7 electric broom vacuum. ZEK is one of the best electric broom vacuum manufacturers.
If the battery runs out below 25 percent, the blue lights will flash one by one when you charge it. The first blue light will stop flashing if it is charged at 25 percent. And then 50 percent, and 100 percent. All of the blue lights will stop flashing when it is fully charged.
If the battery fails to contact the main unit, all of the blue lights will flash 7 times for three turns.
When the machine starts to work, if the blue lights flash two times, the motor might be short-circuited.
If the blue lights flash three times, the motor of the main unit or the electric brush might be stuck.
If the blue lights flash four times, the battery pack's temperature might be high.
If the blue lights flash five times, the battery voltage is low. We may attribute this to the battery itself or the wrong use of the charger.
If the blue lights flash six times, we may use the wrong charger and the voltage is too high.
If the blue lights flash seven times, it indicates no load.
If the blue lights flash eight times, it indicates a battery MOS issue.
