A. The battery voltage is not within the charging range (ie: battery voltage> DC35V), which will make the charger work unstable and burn out

Preventive measures： Before charging the battery, first confirm the voltage range of the product and the voltage range of the battery. If the battery has no relevant parameter identification, use a multimeter (adjusting DC file) to measure its voltage. If the voltage is higher than the charging voltage of the product, do not charge it.

B. The input voltage of the product is AC100-240V, if the input voltage exceeds AC265V, it will cause the charger circuit to burn out.

Preventive measures： Before charging the battery, confirm the voltage range of the AC power source. If not sure about the AC voltage, use a multimeter to adjust to the AC position and measure the AC power source.
