DESCRIPTION OF OPERATION
General
LIFEtech™ MOD1C chargers are microprocessor-controlled. The processor calculates the
battery’s capacity so that the charging profile can be automatically adapted to the battery’s actual
state over a wide range of capacities. The charging coefficient is maintained absolutely on all
types of batteries. LIFEtech™ MOD1C chargers adapt to the battery’s capacity and its discharge
level.
LIFEtech™ MOD1C chargers can easily be set to charge flooded batteries used in cold or
freezer storage applications, ionic or opportunity profiles. This battery charger is also designed
to charge flooded and sealed lead-acid storage batteries within the range of the cell and ampere-
hour rating as marked on the nameplate.
Beginning the Charge
When a battery is connected to the charger, the control board senses voltage and after a 20
second delay, the charger energizes.
Charging
Charging current is determined by the battery voltage and interaction of the charger. Charging
current declines automatically as battery voltage rises during the charge. As the battery charges,
the graphical TFT LCD display will output various charge parameters including the percentage
of battery capacity.
AC Power Fail
If the AC power fails with a battery connected to the charger during a charge cycle, the charger
will reset and start a new charge cycle when power is restored. All charger settings as well as
the time and date are preserved.
Series Charging
In series charging, the voltages of both batteries add up and must match charger’s nameplate
rating. The charger’s ampere-hour rating must be equal to each of the batteries’ ampere-hour
rating. Charge cycle will not start unless both batteries are connected.
