Does the serpentine belt affect the battery?
I know the serpentine belt is connected to many different parts of my car. But, does the serpentine belt affect the battery?

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.
