It just happened to me a couple days ago..I found that my alternator belt broke and had to be replaced.
The battery light coming on in your Town and Country minivan means that the alternator needs to be replaced. The alternator charges the battery and if it goes bad it will not charge the battery.
Usually it means your alternator is bad or going bad.
it means the light on a battery of a computer or cell phone
the battery light means that your battery is being charged properly. so let it light.
What does it mean when the airbag light and battery light on 1999 Ford Escort flashes?
The battery light means your battery is low. You should go to a mechanics.
The light next to the battery warning light is the fuel injection system warning light. If it comes on and goes off after a short while it should be ok but if it stays on for longer than 5-10 minutes then get it checked out.
Get the alternator checked before your battery goes dead.
If you mean the battery goes dead, maybe you need a new battery. Either that or something's drawing it dead. ie: a light staying on someplace (glovebox, trunk light...), bad charging system, etc. Probably the alternator.
Take off the negative battery cable and hook a test light in between the cable and the battery post. If you have a drain, the light will be on. Start pulling fuses until the light goes off and when it does go off, that is the thing that is draining the battery. If no fuses affect it, take the altermator wires off. If the light goes off then, the alt is bad,.
Your battery is not being charged
alternator is going out Or the belt is slipping
