Rebulk Voltage (Advanced Menu)
In the Float stage, if the battery voltage falls below the ReBulk Voltage set point for at least
90 seconds, the FLEXmax will automatically initiate a new charge cycle.

Vbatt Calibration (Advanced Menu)
A quality, calibrated voltmeter will provide even more accurate FLEXmax battery readings if an
undesirable voltage drop occurs. When measuring battery voltage, ensure a good connection is made
to the four wire lugs. Check the battery temperature compensation voltages if the voltages are much
different than expected from the charger setup Absorbing and Float voltage settings.

RTS Compensation (Advanced Menu)
The RTS Compensation screen allows the user to control the Absorbing and Float voltage limits
during charging when using a Remote Temperature Sensor (RTS). The RTS adjusts charging voltage
depending on battery temperature. (See page 97 for the amount of compensation per degree.)
However, some conditions can make compensation less than optimal, such as extreme weather (hot
or cold), or charging restrictions from the battery manufacturer. Therefore, the RTS Compensation
screen allows the user to control the limits used by the compensation feature.
