What are the reasons for a new battery not lasting long?
1 Answers
New battery not lasting long reasons are as follows: Insufficient capacity of the newly replaced battery: Insufficient battery capacity can be judged by the charging time. For example, after the battery is completely drained, charge the battery pack with the previous charger and observe the charging time. If the charging time is close to or slightly shorter than that of a new car, it can be determined that the battery is not faulty. If the charging time is much shorter, battery failure should be suspected. If repeated tests still show the same result, it can be concluded that the battery is faulty. Further inspection can be done using an internal resistance meter to check the internal resistance or a discharge meter to check the discharge voltage. Increased power consumption of the electric vehicle: Check the power consumption of the vehicle. For example, check if the brakes are locked, if the wheel resistance is high, or if the motor bearings are damaged. If no issues are found, suspect if the motor is demagnetized. A demagnetized motor has insufficient power, increased operating current, and naturally consumes more electricity.
