This article from the Automotivean website discusses The battery Charger says Fully Charged but Car Won’t Start.

Have you ever faced a problem where your car’s battery charger says fully charged, but your car just won’t start?

It can be quite frustrating and can leave you stranded in the center of nowhere. Understanding the potential reasons behind this problem can help you analyze and fix the problem quickly.

Possible Causes- The battery Charger says Fully Charged but Car Won’t Start

1. Corroded Battery Terminals

Pollution on the battery terminals can contain a proper electrical connection, even if the battery itself is fully charged. Check the battery terminals for any signs of rust or buildup. Clean them using a battery terminal cleaner and confirm a tight connection.

2. Weak Battery

Although the battery charger indicates that the battery fully charged, it may still be weak. Over time, batteries can lose their capability to hold a charge effectively. If your battery is several years old, it may be time to consider replacing it. Consult with a specialist to determine if a weak battery is the culprit.

3. Faulty Starter Motor- The battery Charger says Fully Charged but Car Won’t Start

A faulty starter motor can prevent your car from starting, even with a fully charged battery. The starter motor is responsible for turning the engine over. If you hear a clicking noise when you turn your key or experience intermittent starting issues, it could indicate a problem with the starter motor. Have it checked by a qualified mechanic.

4. Alternator Issues

The alternator plays a crucial role in charging the battery while the engine is running. If the alternator is faulty, it may not be supplying sufficient power to the battery, even if it appears fully charged. This can result in a no-start situation. A professional diagnosis is necessary to identify and fix any alternator issues.

5. Faulty Ignition Switch

The ignition switch is liable for sending power to the starter motor when you turn the key. If the ignition switch is defective, it may not engage the starter motor, leading to a no-start condition. A professional inspection is suggested to determine if the ignition switch must be repaired or replaced.
