It sounds fine at that voltage to me ..
Try checking it under a load to be sure so lights on main beam on heated seats and anything else you have and then see what the voltage is at the battery .. needs to be 13v or higher .
I would normally check at the alternator and then at the battery to see what the difference is .. this will give you an idea of any resistance in the power line .. 0.6 volts and higher is a problem.
Checking at the alternator isnt easy though so just try my first check .
