A bad battery will not cause the battery light to come on light only comes on when there is a problem with the charging system like the alternator, alternator fuse or a wiring problem.

You need to inspect all of the power and ground wires on the battery and the alternator and look for any rust or corrosion and/or any damage. Make sure you follow them all the way to where each end connects to another point. Then, clean all of the connections and/or replace any wires with damage.
