A pasting carrier for a lead-acid battery comprising: (i) a nonwoven fiber mat having a thickness between 0.13mm and 1.27mm (5 and 50 mils) measured in accordance with ASTM D5729, (ii) the nonwoven fiber mat being composed of a plurality of entangled glass microfibers comprising: (a) between 30 and 60 weight percentage of smaller sized glass microfibers having an average fiber diameter between 150 and 550 nanometers, said average fiber diameter measured by SEM microscopy taking three images across the mat and the counts and measures the fiber diameters is performed by a software protocol which counts and measures the fiber diameters; (b) between 0 and 40 weight percentage of larger sized glass microfibers having an average fiber diameter between 0.6 and 6 microns, said average fiber diameter measured by SEM microscopy taking three images across the mat and the counts and measures the fiber diameters is performed by a software protocol which counts and measures the fiber diameters; and (c) between 15 and 60 weight percentage of a binder that binds the smaller sized glass microfibers and the larger sized glass microfibers together, the smaller sized glass microfibers and the larger sized glass microfibers being substantially homogenously or uniformly distributed and blended throughout the nonwoven fiber mat.
