In the event of a fault, the steps to eliminate the cause of the fault step by step 1. Test the open circuit voltage of the battery 30 minutes after removing the battery from the electrical appliance. If the open circuit voltage of the battery is ≥3.65V, it means that the battery still has more than 10% of the rated capacity. If the open circuit voltage is less than 3.65V, it indicates that the rated capacity of the battery is close to exhaustion, and if the open circuit voltage is less than 3.0V, it indicates that the remaining capacity of the battery is less than 2%. 2. Use the maximum current required by the customer to test the battery, test the load voltage of the battery within 30S, and observe which range the load voltage of the battery is in. If it is in the first range, there are many reasons for the analysis and elimination of the lag, and I will not explain it here; If it is in the second interval, it means that the battery is not the cause of the fault. First of all, the customer’s electrical appliance itself must be found for the problem; if it is in the third interval, it may be the battery itself or the electrical appliance. The following will Give a detailed explanation for this situation. 1.0V
