The battery light obviously means the control module is not seeing proper charging voltage. This is between 13.2 and 14.8 volts when the engine is running.
Let's start at the beginning and find out what your alternator is actually producing. Take a volt meter and put it on the battery posts when the engine is off and tell me what you have. Then start the engine and tell me what the reading is. Obviously red lead goes to positive and black to negative and make sure it is set to volts.
If this is not within spec then we need to address that even though they are new they are below spec and causing the light to come on.
If they are within spec, we can run down a false light. This is rare on these older vehicles which makes this one a head scratcher.
