*Note:  All Deltran battery chargers will charge all types of lead acid batteries: either flooded (standard STD), sealed maintenance free Absorbed Glass Mat (AGM), or sealed maintenance free gelled electrolyte (GEL) batteries.  However, for optimum battery performance in deep cycle applications (for example, running a trolling motor), it is best to chose the Deltran charger that has the charging software specifically designed for the battery type.  Fortunately, since the technical staff at Deltran has developed charging software that works equally well for both STD & AGM batteries, the only choice to be made is between 2 models: either STD & AGM or GEL software.
