VDB0-B195D is a massive, blue star cluster in M31. It was observed as part of the Beijing-Arizona-Taiwan-Connecticut (BATC) Multicolor Sky Survey using 15 intermediate-band filters covering a wavelength range of 3000-10000 Å. Based on aperture photometry, we obtain its spectral energy distribution (SED) as defined by the 15 BATC filters. We apply previously established relations between the BATC intermediate-band and the Johnson-Cousins UBVRI broadband systems to convert our BATC photometry to the standard system. A detailed comparison shows that our newly derived VRI magnitudes are fully consistent with previous results, while our new B magnitude agrees to within 2σ. In addition, we determine the cluster's age and mass by comparing its SED (from 3000 to 20000 Å, comprising photometric data in the 15 BATC intermediate bands, optical broadband BVRI, and Two Micron All Sky Survey near-infrared JHK_sdata) with theoretical stellar population synthesis models, resulting in age and mass determinations of 60.0±8.0 Myr and (1.1-1.6) x10⁵ M_☉, respectively. This age and mass confirms previous suggestions that VDB0-B195D is a young massive cluster in M31.
