In general, changing the battery in your Ford Fusion should be a simple task without many issues. Using the right group battery with sufficient cold cranking amps is crucial for proper vehicle performance. If your new battery dies soon after replacement, the likely culprit is a faulty alternator, which charges the battery and powers electrical components while the engine is in operation. It's recommended to have an alternator test to ensure it is charging correctly, as a failing voltage regulator is a common issue that can lead to damage.
When the battery doesn't have sufficient charge to start the engine or operate electrical parts, it is classified as dead. Typically, you'll notice dim interior lighting in the vehicle and the engine may crank slowly or not at all during starting attempts. If there is still some charge remaining in the battery, you might hear a rapid clicking noise, but the vehicle may be completely unresponsive in most instances.
