FLOAT MODE
The third mode of charging is what is called the “oat” charge. This mode is designed to
provide a “trickle charge” to the battery after the system observes no signicant variations in
current draw over a long period of time. When in “oat” mode, the voltage will reduce from
13.6V to 13.2V and supply the “trickle charge” which helps to preserve the life of the battery
while keeping it charged and ready for use. A change in DC current will cause the converter to
exit the mode and return to the Absorption mode and then to Bulk mode if required.
LITHIUM TWO-STAGE SMART CHARGING
The two-stage “smart” charger continuously measures the battery voltage output and
regulates the amount of charge using two modes of operation: Bulk and Absorption mode.
