A Deka golf cart sealed gel battery does not need equalization. If the Deka is a flooded cel such as GC10, GC15, or GC25 golf cart battery then the equalization voltage would be 7.5 volts for 2 hours or less, or of course 15 volts with two in series. Note that the battery will vigorously gas giving an explosive mixture of oxygen and hydrogen gas. Unplug the battery charger from the wall before removing cables from the battery as a spark can cause an explosion spraying 32% sulfuric acid. Some recommendations range from once a month to once a year. I like the Trojan battery recommendation, which is equalize if there is wide ranging specific gravity (+/- .015 measured with a hydrometer) between cells after fully charging a battery, or if the hydrometer shows the battery has not reached full charge after charging with an intelligent charger. Trojan recommends monitoring the specific gravity every hour until the required level is reached. Over charging for equalization can erode the lead oxide from the battery plates shortening the life of the battery so why do it unless it is really needed.
