Depending on the vehicle and electrical system, this can happen, even if the battery is not dead, but only to "low."
Alternator is defective or battery has a dead cell.
Eventually, yes, it will.
battery light indication means a dead battery or a dead alternater/regulater or a fault in the charging/ignition system
your alternator is bad even if you charge your battery it could still die because the battery is being wasted while you drive
A completely dead battery or a bad connection to the battery.
You may need a new alternator and or battery.
It has to be a dead charging system.... usually a short internal in the alternator
If its totally dead (no radio, no starter) I would first look at your alternator/battery. This happened to my 2003 Trailblazer, and we had to replace the serpentine belt and the alternator. Battery light came on while driving and within ten minutes, the car was dead.
Car battery polarity can only reverse if the battery is completely dead and then charged with the neg. and pos. leads of the charger are reversed. This is very dangerous as hydrogen gas which is given of buy a dead battery may explode and cause personal inguiry.Likewise if the car's battery cables are accidently reversed while the battery is dead.

Use a battery charger.
