Then it's probably the voltage regulator, or the battery itself.
Still have the charging system tested. It's better to have it tested and know what is wrong, than to guess.
They can test everything on the vehicle, including the battery.

NEVER ever disconnect the battery with the engine running.
You have probably damaged a diode in the alternator.
That is a carry over from thge days of GENERATOR's (DC)
Alternators are A/C (& DC) they require a place for the generated current to go. ie: The Battery
BTW> That's also called an AMP or ALT light ....not a battery light.
It measures the amperage the alternator & VR are putting out.
To measure the Battery ...a VOLTmeter would be installed.
