I think this guy is just charging up as needed.
Basic, cheap battery chargers generally charge at only 14.4 - 14.6 volts regardless of the acceptance rate of the battery being charged.
A "smart" charger will charge at, depending upon the battery type setting, 14+ for the bulk phase, 13.8 for the absorption phase and 13.2-13.4 for the float phase thus causing no damage to the batteries.
