Most alternators need to spin at about 2,400 rpm at idle, have their maximum output above 6,000 rpm, and should never exceed 18,000 rpm.

TL;DR: The alternator charges the battery as fast as the battery will let it, or as fast as the alternator can, whichever is lower, at a constant voltage (usually 13.8v, or 14.2v). The terminal voltage going down to 13.1v suggests the battery is not charging, and may be discharging, unless the battery is very low.

The minimum RPM is highly dependent on the specification of alternator. But a basic alternator will produce charging current anything above 2000 rpm. We can safely …
