The multiple-muon events, recorded nearly continuously from August 2003 until April 2012, comprise two independent data sets imaged with opposite magnetic field polarities, the comparison of which allows the systematic uncertainties of the measurement to be minimized. The multiple-muon charge ratio is determined to be $R_\\mu = 1.104 \\pm 0.006 {\\rm \\,(stat.)} ^{+0.009}_{-0.010} {\\rm \\,(syst.)} $.
