The results by A.S. Barabash [Phys. Rev. { \bf C 81}, 035501 (2010)] are shown to be incomplete. Tellurium data sets were reanalyzed using the best practices of ENSDF evaluations. Present analysis indicates much higher value for the 2$\nu$-mode half-life time in $^{ 128}$Te and the corresponding ratio of $^{ 128,130}$Te half-lives. These values imply the $T^{ 2 \nu}_{ 1/2}$ $\sim$ $\frac{ 1}{ E^{ 8}}$ $\beta\beta$-decay transition energy trend that is consistent with the two-nucleon mechanism of $\beta\beta$(2$\nu$)-decay.
