No. According to the query on iPurchasing.com, it is known that old batteries have a small capacity, which means that the electricity discharges very quickly when discharging and the charging time is also very short, i.e. -say that the maximum voltage has been reached. Put the new and old batteries together in parallel. When discharging, the old battery will discharge quickly and the voltage will drop accordingly, and the new battery will charge the old battery, and the overall discharge time will be shortened, which will also affect the battery life. the new battery. Therefore, new and old lithium batteries cannot be used in parallel.
1. The parallel connection is positive pole to positive pole and negative pole to negative pole. It's the same as general polar components don't change the voltage, but the output current increases exponentially.and the internal resistance also decreases, the carrying power has also been increased significantly, because the current has also increased.
2. Directly connect the positive pole to the positive pole and the negative pole to the negative pole of two lithium batteries of the same model.
