Bad cell in battery will have these kinda voltages
Check fuse for Alt and it's wring connections
Check ground wire end to end of battery and main engine ground
If not Alt or battery you need to use a good OBD-II scanner and see that the PCM is commanding the ALT to output
Too many electronics on cars today so if car sits for days then a battery tender is a must.
