The Fixed (D1-02=1) charge curve will have a fixed Absorption Time (D1-06).
The Adaptive (D1-02=2) and AdBattery safe (D1-02=3) curve derive the
Absorption time from the Bulk time. The maximum Absorption time of these charge curves
is determined by Absorption Time (D1-06) setting.
The Ad Battery safe (D1-02=3) curve has a special regulation in the absorption
phase. The absorption phase will start when the battery voltage reaches 14.4V( for 12V
batteries) regardless of the specified Absorption Voltage (D1-03). During the absorption
phase, the voltage will increase with a fixed ramp until the voltage reaches the absorption
voltage or the calculated absorption time is over in the latter case, the absorption phase will
end before the absorption voltage is reached.
