Alert! Low system battery voltage. Reset the Bios to Defaults

When I boot up my PC (Optiplex 755) it beeps and says my system battery voltage is low. I replaced the bios battery and it's still saying the same thing.

The event log didn't have anything about the battery but I'm not getting the alert anymore.
