on, the battery charge level lights correspond only to battery voltage, not
charging stages (see
Load Light Table
, Page 8).
• Bad Cell
light flashes
RED
if the charger has not completed the
Constant Current
stage in 20 hours and battery voltage is under 11.5V
( Flashing), or if the battery is under 11.5V after a
Battery Test
( Flashing).
The charger shuts off output to avoid any damage to your battery. Loads
or banks of batteries may trigger this mode if they are too large for this
charger. Remove any loads and charge batteries individually.
• Testing
light flashes
BLUE
when the unit is performing a
Battery Test
(see
Charging Stages
).
• Desulfation
light flashes
BLUE
any time the unit is desulfating. The
BatteryMINDer desulfates any time it is outputting current.
• Temperature Compensation
light is
GREEN
if the temperature is over
27°C/80°F,
BLUE
if the temperature is under 21°C/70°F. BatteryMINDer
CEC model includes an ambient temperature sensor which allows it
to vary the output voltage as necessary to properly charge your 12V
(-0.025 V/°C) or 24V (-0.050 V/°C) battery. Batteries charged at higher
temperatures without compensation will overcharge and may out-gas.
Batteries charged at lower temperatures without compensation will
undercharge allowing sulfation to build, possibly leading to the battery
freezing. By using temperature compensation, the BatteryMINDer
ensures your battery will never over or under charge, even in extreme
conditions.
Consider using accessory ABS-248 “At the Battery Sensor” for more accurate
temperature compensation. It is highly recommended if your battery is located
in a different environment or compartment than your charger.
