In the process of the use and maintenance of lithium ion power batteries, the battery or battery system may appear in the following or more abnormal state. Please organize the professional engineering and technical personnel according to the prompts of this manual. If you have any questions about the cognitive or processing method of the state, please contact the company's related technical departments or after -sales service departments in time to obtain professional technical support.

　　1. If the battery is found to have abnormal mechanical features such as bulging, shell rupture, shell melting, and distorted shells before installation and during installation, immediately stop using the battery and stored separately;

　　2. If the battery is found to be loose, cracked, insulating layer rupture, marks, burns, etc. if you find the battery's chip tight bolts, conductive bands, main circuit wires and connecting plug -ins in the process of installation. Reason and repair;

　　3. If the polarity of the positive and negative electrodes of the battery before installation is not consistent with the polar identity, please immediately stop using the battery and contact the after -sales service department to replace the battery or obtain other processing methods;

　　4. If the actual voltage of the battery is found to be lower than 2.00V before installation and during use, the battery should be stopped immediately, and then the battery is charged with a 3.65V0.02C balanced charger. Pay attention to the voltage of the battery in the entire process. Changes, temperature changes, etc., when the battery charges the voltage between 3.60 and 3.65V, the charging current is less than 0.01C, and the charging can be stopped. Above 3.33V, the temperature is basically the same as the environmental temperature. If the battery opening voltage and temperature are not met with the condition after being held, the battery is considered abnormal. Please contact the after -sales service department to obtain support information;
