VDB0-B195D is a massive, blue star cluster in M31. It was observed as part ofthe Beijing-Arizona-Taiwan-Connecticut (BATC) Multicolor Sky Survey using 15intermediate-band filters covering a wavelength range of 3000--10,000 \AA.Based on aperture photometry, we obtain its spectral-energy distribution (SED)as defined by the 15 BATC filters. We apply previously established relationsbetween the BATC intermediate-band and the Johnson-Cousins $UBVRI$ broad-bandsystems to convert our BATC photometry to the standard system. A detailedcomparison shows that our newly derived $VRI$ magnitudes are fully consistentwith previous results, while our new $B$ magnitude agrees to within $2\sigma$.In addition, we determine the cluster's age and mass by comparing its SED (from3000 to 20,000{\AA}, comprising photometric data in the 15 BATC intermediatebands, optical broad-band $BVRI$, and 2MASS near-infrared $JHK_{\rm s}$ data)with theoretical stellar population synthesis models, resulting in age and massdeterminations of $60.0\pm 8.0$~Myr and $(1.1-1.6) \times 10^5 M_\odot$,respectively. This age and mass confirms previous suggestions that VDB0-B195Dis a young massive cluster in M31.
