Battery Charge Stages and Meanings
Bulk MPPT
This stage of The Kid means; that The Kid will be putting out as much current as it can trying to charge
the batteries to the absorb voltage set point. This is also known as constant current mode.
Absorb
This stage means that The Kid will maintain the absorb set point voltage until the batteries are charged
or it reaches Float stage. At this stage The Kid is 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 battery is considered “full” at the end of the absorb charge cycle.
The absorb time is proportional to the bulk time. (i.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 is held at the float voltage set point, float time can be changed by the user.
Equalize
The intent of an equalization charge is to bring all battery cells to an equal voltage by a deliberate
overcharge. The goal is to return each battery cell to its optimum condition through a series of voltage
controlled chemical reactions inside the batteries.
