Why is the new battery still showing a red light after 9 hours of charging?
1 Answers
The reasons why the new battery still shows a red light after 9 hours of charging are as follows: Battery and charger mismatch: If the electric vehicle battery does not match the charger, the charging speed will be slow, or even fail to charge. Simply put, the charger power may be lower than the battery power. Check the parameters of the battery and charger. If they do not match, re-match the battery and charger to ensure they have the same power. Battery dehydration fault: Many users usually do not pay attention to battery maintenance. Overcharging or charging with high current can easily cause the electric vehicle battery to develop a dehydration fault, resulting in the charger always showing a red light.
