Default Low Voltage
I was getting a low voltage reading at low rpm after the car was running for a few minutes; it was kind of OK on start up; high 12v low 13v. After about 10 minutes voltage decreases to low 12s high 11s. Subsequently, my battery died.

Today I replaced the voltage regulator, alternator, and battery (battery was confirmed bad at AutoZone).

Better on start up, mid 13s but after 10-15 minutes high 11s low 12s again. Any ideas?
