Sometimes the explosion-proof working lamp needs to be charged after it runs out of power, but sometimes it will fail and cannot be charged. Why?

  1. Test whether the lamp battery is damaged

    Detection method: this method is very simple. We only need to take out a good charger and confirm it to charge the lamp. If it can be charged, it means normal; if it cannot be charged, it means the battery is damaged.

 2. Check whether the charger is damaged

    Detection method: turn on the green light after charging, and the red light after charging. If the indicator light of the charger is not bright, we can judge that the charger is damaged. The charger under the same model can also be called for detection.

 3. Test whether the lamp power supply is damaged

    Detection method: determine this kind of problem we just need to pay attention to, in the light of a sleepy, whether the light bulb filament is red, if there is no reaction, if not then determine the power supply damage.
