The meter will be telling you the r.m.s value of the AC waveform which is the equivalent voltage for power delivery... the peak voltage of the waveform is higher than that. A 10.1v r.m.s sine wave will have a peak voltage of 14.3v, a spikier waveform will have an even higher peak. The top bit of the waveform (i.e. above whatever the battery voltage is) is where the diode goes into conduction and starts delivering useful current to the battery.
