Here's why:
* Connection: Even with a new battery, there's a chance the connections weren't made correctly. Make sure the positive (+) and negative (-) terminals are firmly secured to the battery posts.
* Battery Charge: New batteries often arrive partially charged. A full charge might be needed before the car will start.
* Other Issues: The issue might not be the battery. Your car could have other problems like a faulty starter, alternator, or fuel system.
To ensure your car starts after a new battery:
1. Double-check the connections: Make sure the battery terminals are tight and properly connected.
2. Charge the battery: If the battery is new, give it a full charge with a battery charger.
3. Attempt to start the car: If it doesn't start after charging, you may need to investigate other potential issues.
Always refer to your car's owner's manual for specific instructions.
