Question:

Led charging searchlight, when charging, did not switch off, how bad repair?

Led charging searchlight, when charging, did not switch off, how bad repair?

Answer:

But if LED work in the high voltage state, the longer the more dangerous, because the charging voltage will be gradually increased with increasing voltage, the charging time of the battery (start because the battery voltage is low, will pull the charging voltage), when the voltage is higher than a certain value, it will burn bad LED.
In this case, the battery will not be a problem, mostly LED is burned out, because the charger output voltage is higher than the battery voltage, so as to ensure that the rechargeable battery can charge properly
