Brake + Battery Light

I just upgraded my alternator in my NX to a 2001 altima alty. But when each 
one of my autozone alts went bad, the battery light was always on at idle, 
it was never intermittent. This was consistant with the last 5 alts that 
have gone up on me. Hopefully this nissan one with last longer
