During cold weather, a battery often requires a higher
recharging voltage. Lower quality inverters might not
accommodate these higher voltages and can shut down
during recharging, cutting o power to their loads. The
FLEXmax 80 allows the user to lower the compensated
voltage in the Absorb cycle so these inverters will remain
operating. Also, some batteries have an absolute voltage
limit that should not be exceeded and the WIDE/LMIT
option allows the user to control this during recharging.
WIDE allows the RTS full control over recharging; LIMIT
sets the ceiling and oor voltages for the RTS.
During hot weather, the LIMIT feature set point assures
recharging will continue at a high enough voltage rather
than dropping too low in reaction to a higher ambient
temperature. This assures the recharging voltage ad-
equately charges, but should be monitored according to
the battery manufacturer’s recommendations.
The RTS default compensated voltages apply if the WIDE/
LIMIT option is set to WIDE. To change these values, press
the <WIDE> soft key to bring up the next screen which
allows user-determined limits. Press the <SET> soft key
to adjust these values.

A quality calibrated voltmeter will provide even more
accurate FLEXmax 80 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 dierent than you expect from
the charger setup Absorb and Float voltage settings. Use
the <-> and <+> soft keys to match the readings from
the voltmeter (use of appropriate wire gauge will mini-
mize voltage drop). When nished, press the <NEXT>
soft key to view the RTS Compensation screen.
