Pontiac Sunbird Battery Problem

My battery light came on, but all electronics are working. Could it be the starter?

Does the starter motor crank? Cranking rpms ok? If so, I think your starter is ok. Id use a digital multimeter across battery posts, everything off, the generic spec for a full charge is around 12.6 volts. Leave leads hooked up to battery posts, have a helper turn key to crank, how far does the voltage reading drop? Shouldn't drop below 9.6 volts, generic spec.
