DESCRIPTION OF OPERATION
General
The LIFEPLUS MOD3 series of chargers are compatible with batteries at 24, 36, 48 volts or
72, 80 volts, depending on model.
The LIFEPLUS MOD3 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. LIFEPLUS MOD3 chargers adapt to the battery's capacity and its discharge
level.
LIFEPLUS MOD3 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 amp-hour rating
as marked on the nameplate.
Auto Start Charge
When a battery is connected to the charger, the control board senses the voltage and after a 20
second delay, the charger starts charging the battery automatically.
Charging Current
Charging current is determined by the charger based on battery voltage and its state of charge.
Charging current declines automatically as battery voltage rises during the charge. As the battery
charges, the graphical LCD display will output various charge parameters including the charging
current.
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 amp-hour rating must be equal to each of the batteries' amp-hour rating.
Charge cycle will not start unless both batteries are connected.
