If the battery light is still on, the chances are your battery might not have needed replacement. The battery light is simply an indicator for the whole charging system. A bad battery, bad connection, bad alternator, bad regulator, etc. are all things that can cause the light to come on. A charging system test should be able to pinpoint the cause. A mechanic, such as one from YourMechanic, can perform a load test, voltage and amperage output test, and voltage drop test to determine the cause of your Battery Light.
