Selecting a Charging Profile & Understanding Battery Types
Your battery charger is equipped with a user programmable battery type selector that is factory set for
standard Flooded (lead-acid) / AGM (Absorbed Glass Mat) batteries.
To set your charger for Gel batteries simply remove the black programming cap and replace it with the Gel
programming gray cap. If you own a ProSport 20 Dual Bank Charger you also have the option to use the
High Performance AGM profile recommended for OPTIMA BlueTop Deep Cycle and Odyssey AGM marine
batteries by installing the blue AGM HP programming cap. Any time you reprogram or change the cap, apply
marine silicone to the threads of the cap being installed.
NOTE: AGM (Absorbed Glass Mat) batteries are not Gel (Gelled Electrolyte Lead-acid) batteries. Gel
batteries require a completely different charge profile that must be selected versus the out of the box
factory setting.AGM batteries can accept the same charging profile as Flooded (lead-acid) batteries.
Understanding Battery Types & Charger Settings
There are three primary types of batteries in the marketplace today; standard Flooded (lead-acid), AGM
(Absorbed Glass Mat), high performance AGM and Gel cell (Gelled Electrolyte Lead-acid). Traditionally, the
most common type of batteries used are Flooded (lead-acid) batteries. Almost all Gel cell batteries will state
that they are Gel cell on the battery case or labels. Shown below are typical battery voltages at absorption
and float levels.

factory setting. AGM batteries can accept the same charging profile as Flooded (Lead-acid) batteries.
