Linc, something may be wrong with your converter.
At 12.1 volts, your battery was discharged 50%. At 50% you are on the borderline between Bulk Charge Stage (14.4 charging Volts) and Absorption Stage (13.6 Volts).
12.9 volts could mean something bad is going on with either your battery or converter.
Were you using a digital voltmeter or the status lights to determine the battery voltage?
You may need to do some tests including a LOAD test on the converter to make sure it is working to Spec.
