Battery Charge Warning Light on a Saab 900
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Battery Charge Warning Light Means on a Saab 900
The battery/charging light on a Saab 900 does not mean 'battery low' — it means the charging system is not keeping the battery topped up while you drive. Usually that points to the alternator or its belt rather than the battery itself.
How Urgent Is the Battery Charge Warning Light?

A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Saab 900 still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.
