Figure 5-7, Bulk Charging Mode
• Bulk Charging – The battery charger is delivering maximum current
(determined by the Setup 03C Max Charge Rate setting) to the batteries. The
charger will remain in Bulk charge until the absorb voltage (determined by
the Setup 03B Battery Type setting) is achieved.

Figure 5-8, Absorb Charging Mode
• Absorb Charging - The Absorb charge state is the constant voltage
stage and begins when the absorb voltage is reached (determined by the
Setup 03B Battery Type setting) while Bulk Charging. During this stage,
the DC charging current decreases in order to maintain the absorb voltage
setting. This charge stage continues until 03E Absorb Done (Time, Amps or
SOC) or 03F Max Charge Time is reached.

Figure 5-9, Float Charging Mode
• Float Charging – At the end of the Absorb Charge time, the charger
reduces the charge voltage and tries to maintain the batteries at the Float
charge voltage setting; which is determined by the Setup 03B Battery Type
setting as shown in Table 3-3, Battery Type to Charge Voltages.
Info: If the battery voltage falls ≤12.1 VDC (12-volt models), ≤24.2
VDC (24-volt models) or ≤48.4 VDC (48-volt models); the unit will
initiate bulk charging.
