So MA Battery Charge Stages and Meanings Bulk MPPT This stage of the Classic means that the Classic will be putting out as much current as it can trying to charge the batteries to the absorb voltage set point This 1s also known as constant current mode Absorb This stage means that the Classic will maintain the absorb set point voltage until the batteries are charged or it reach Float stage At this stage the classic 1s not putting out maximum current as that would increase the battery voltage over the Absorb set point This is also referred to as constant voltage mode The absorb time is proportional to the bulk time 1 e the time bulk takes to reach the absorb voltage The battery it s considered full at the end of the absorb charge cycle Float A Float cycle follows after the Absorb cycle is completed Float is displayed on the screen Battery volt age 1s held at the float voltage set point float time can be changed by the user Equalize Equalization function has to be enabled by the user refer to page 25 The intent of an equalization charge is to bring all battery cells to an equal voltage by a deliberate overcharge The goal 1s to return each bat tery cell to its optimum condition through a series of voltage controlled chemical reactions inside the bat teries Adjusting Absorb Equalize and Float Voltages Setting the Classic though the wizard will set Absorb Float and EQ to the factory default set voltage
