An Absorb charge cycle normally ends when a battery voltage is maintained at the Absorb set point for the user- determined time period. Use the < ->or

<+ > soft keys to adjust the Absorb End Amps to an optimal value (the default value is 00). While the battery voltage is at or above the Absorb target and the Absorb End Amps value is reached for a time delay of 15 seconds, the FLEXmax 80 will switch to the Float stage regardless of the charger time minutes as shown in the Misc menu under ChgT. The charger timer will be cleared. This is an optional set point and is used for few installations.

When finished with any adjustments, press the <NEXT> soft key to view the Rebulk Voltage screen.

In Float, if the battery voltage falls below the ReBulk Voltage set point for at least 90 seconds, the FLEXmax

80 will automatically reinitiate a Bulk charge cycle. The default is set to 6 volts, a very low value that will disable this function. The Rebulk Voltage value can be adjusted by pressing the < - > or < + > soft keys. Press the <NEXT> soft key to view the Vbatt Calibration screen.
