The battery warning light often indicates that the alternator is not charging the battery properly. Possible causes include a worn-out voltage regulator, broken belt, or poor electrical connections.

Yes. If the alternator is undercharging or overcharging, it can either fail to recharge the battery or damage it, leading to frequent battery failure—even after replacement.

Common signs include dim headlights, engine stalling, unusual noises, burning smells, and difficulty starting the engine.

An alternator can typically last between 80,000 to 150,000 kilometers (about 50,000 to 100,000 miles), depending on driving conditions and electrical load.

Common causes include worn brushes or bearings, a damaged stator or rotor, faulty voltage regulator, and overheating due to poor ventilation.

Each option has its pros and cons:

• Used Alternator:
  Affordable, but condition and lifespan are uncertain. Internal wear may not be visible, and there’s no guarantee how long it will last. Best suited for short-term use or temporary fixes.
• Rebuilt Alternator:
  A cost-effective and reliable option when rebuilt by professionals using genuine components. It’s fully inspected, worn parts are replaced, and performance is restored. Ideal for those seeking quality and savings.
• Brand-New Alternator:
  Offers maximum reliability and warranty coverage, but typically comes at a higher price. Best for those prioritizing long-term peace of mind and minimal downtime.
