The the alternator is defective.
its the alternator if the car is running with a battery light on. but check fuses first
That light doesn't mean that your battery needs to be replaced. It means that your battery is not being charged while the car is running. Have your alternator tested.
Reasonable chance of an alternater and/or battery.
You can put in a new battery in the car. Then press down on the maintenance button so that the battery light comes on. You will then have it reset and ready to go.
something is draining the battery. a new battery will last a couple days if just starting the car. even if your alternator is bad.
because the battery needs charged or need a whole new battery
Keep the car light on
The car light? YES! Leaving your car light on WILL make your battery run out. Things like leaving your car door open if the light is on because it is open will cause the lgiht to Mae your car battery run out. There is a big difference between shorted out a car battery and running the battery down. Lighting in itself won't short a battery out but will run it down.
the battery light means that your battery is being charged properly. so let it light.
The car may need a new alternator.
Was it running before the old battery went south? Did you have a check engine light before you replace the battery?
Possibly the alternator is defective and not recharging the battery. Or something is on, pulling power from the battery when the car is not running. Can be any light or any relay that is stuck.
