Top 5 Best Aftermarket Car Alternator Brands

Every car requires an alternator to generate power for its electrical system and battery. All of the electrical systems and electronic devices in your vehicle get their energy from the alternator as the engine runs.

Some of these systems and devices include your air conditioning, heating, radio, GPS system, ignition system, stereo system, and the list goes on. Also, the alternator is responsible for recharging the car battery after the engine is started.

Once your alternator goes bad, the battery will attempt to supply power to all the electrical systems and devices but it won’t last very long. The battery will likely go dead within a matter of minutes after the alternator goes dead.
