The battery light doesn't mean you need a new battery it means that the battery charging system is faulty, that is the alternator and the voltage regulator, the lights are on because the system voltage is low, they will not turn off until the charging system problem is diagnosed and repaired.
FYI - The battery light doesn't necessarily mean that there is a problem with the battery. It means that the battery is being discharged faster than the charging system can supply it with a charge. This usually means there is a problem in the charging system, often with the alternator. Have the charging system checked and replace the bad component(s).
your car has an alternator that is supposed to charge the battery. The light comes on when it doesn't. Most likely your alternator needs to be fixed, though it could simply be a loose fan belt.
"Battery charge system" means "Alternator" and the associated wiring.
have the alternator bench tested as it may have a faulty rectifier pack in it
charge lights basically work by when not running the current flows from the battery to the alternator through the light
when the alternator starts to charge it puts a reverse current back through the light in opposition to the battery and so the light goes out
if the light stays on then that means that the current from the alternator is alternating and the battery is keeping it on.
Battery light normally means the charging system is not working.
Take it to an auto store and have them check the charging system.Usually free of charge.
Could be an alternator or something as simple as a fuse.
The battery warning light means the alternator is not charging the battery. And the check engine light is probably for the same issue. Have you had the charging system checked ?
This light means that most likely your alternator has stopped functioning, and your battery is no longer being charged. Typically this means that your alternator needs to be replaced.
How long has the light been on? Although the battery is ok, it most likely means it is not charging. Take the suburban to a parts store for a free check of the system. They should be able to determine if the alternator not charging.
