Your car’s battery is like its heart – it provides the initial surge of power needed to start the engine. Without a healthy battery, you’re dead in the water.

The Role of the Alternator

While the battery starts the engine, the alternator is responsible for keeping it running and charging the battery. If the alternator fails, even a good battery won’t help.

Electrical System Issues

A complex web of wires and components powers your vehicle. If there’s a fault in this system, your car may not start, even with a good battery.

FAQs

2: How can I tell if it’s the battery or another issue causing the starting problem?

If the engine cranks but doesn’t start, it could be due to fuel or spark issues. Consult a mechanic for a thorough diagnosis.
