DESCRIPTION OF OPERATION

General

The LIFESPEED MOD3 series of chargers are compatible with batteries at 24, 36, 48 volts or
72, 80 volts, depending on model.
Battery recognition (voltage, capacity, state of charge, temperature, etc.) is accomplished by
wireless communication from the Battery Boss®. Battery management is optimized through
use of the Battery Boss®. Three charging profiles are available based on the configuration
chosen by the operator. Furthermore, desulfation, equalization and compensation charges are
integrated.

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.
