The serpentine belt does affect the battery. The belt keeps the alternator spinning, and those rotations in turn power your:
  • Steering system
  • Electrical system
  • Air conditioning
  • Other mechanical components in your engine
One of the most important things your alternator does is recharge your battery while you’re driving. If you’ve got a worn-out serpentine belt, your alternator won’t spin as frequently and won’t have the power to do all of its jobs.
A faulty serpentine belt could cause a domino effect of issues for your engine, so if you think something is wrong with it, you should get it checked out right away.
