Why Can't the Car Start After Replacing the New Battery?

[JocelynLee]

If a car with a newly replaced battery still cannot start, the reason is usually due to faults in the starter or engine. After turning the ignition key, listen for a "clicking" sound from the engine compartment. If you hear this sound, it indicates that the starter is functioning properly, and the issue lies within the engine system. If the engine compartment remains quiet without any noticeable "clicking" sound, the problem is likely with the starter, and you should take the car to a repair shop for maintenance. Batteries require regular maintenance. If left unused for extended periods, they can gradually discharge on their own, leading to complete depletion and eventual failure. It's advisable to drive the car at least a few times each month—not only to ensure the engine and transmission operate adequately but also to recharge and maintain the battery. If the car remains parked for long periods without regular starts, special attention should be paid to battery maintenance. Disconnect the battery from the vehicle's electrical system if the car won't be started for an extended time to prevent continuous discharge and eventual failure. When disconnecting the battery, always remove the negative terminal first, followed by the positive terminal.
