2Introduction to the
Intelligent Multi Charger
The Intelligent Multi Charger (IMC) is a robust, intelligent, fast charging device
designed to charge ‘C’, ‘D’, ‘AAA’ and ‘AA’ cell rechargeable batteries. The user
initiated conditioning (discharge before charge) facility allows the cycling of
batteries if required.
The IMC has been designed for global portability, and can operate from a wide
range of power sources. Automatic detection of input power allows the IMC to run
from 100 V to 240 V AC mains and generator supplies without the need for user
intervention.

IMPORTANT
Always remove charger from carry bag before use.

This section explains various charging modes and
when to use them.
Rapid Charging Mode (Default)
Rapid Charging Mode is the default setting and offers
the shortest recharging time (approximately one to
three hours for ‘C’ cell and one to five hours for ‘D’
cell).
Soft Charging Mode
Soft Charging Mode maximizes battery life and
performance. It is suitable for most batteries and is
recommended if recharging time is not critical.
Conditioning Mode
Conditioning Mode is a special mode which
rejuvenates and cycles batteries. It applies a special
initial charge, discharge and recharge cycle which
restores battery performance (requires up to 30 hours
for ‘C/D’ cell batteries).
The conditioning cycle can be used to recondition
degraded batteries and exercise infrequently used
batteries. It is recommended for use once every
ten normal charges for NiMH batteries to ensure
performance.

Note: In all modes, the
backlight on the LCD will
remain on until the charger
is disconnected from the
mains supply.

Set-Up Procedures for
Charging Batteries
AC Mains and Generator
Using automatic supply voltage detection, the IMC can operate from most AC Mains
supplies around the world. AC power will also be accepted from most portable
generator sets.
A generator capable of supplying a nominal 100 V or 240 V is suitable as a source
of power for the IMC. It is important that only self-regulating generators are used.
A generator that has to have its speed manually adjusted as different loads are
connected and disconnected is unsuitable for use with the IMC.
To charge batteries:
1. Remove the charger and power supply module from the carry bag.
2. Connect one end of the supplied AC power lead to the AC socket located on the
end of the power supply module (refer Figure 3).
3. Connect the other end of the power lead to the AC power outlet or mains or a
generator.
Figure 3 - AC Power Supply Module
On application of power, each symbol (shown on the LCD display) from right to left
will be displayed for approximately 0.5 second. Once this test is complete and there
are no batteries in the charger, the display will go blank. The IMC is now ready for
use.

6Battery Charging
Procedure - Rapid
Note: As rechargeable
batteries can only be fast
charged between 0°C and
+45°C, direct exposure
to sunlight, snow or ice
could prevent the IMC from
entering fast charge mode.
Ensure the IMC is protected
from rain, snow or any other
liquid.
Note: Rechargeable
batteries gradually become
warmer whilst being
charged. Therefore, if warm
batteries are inserted into
the IMC, the charger may
establish, after only a short
time, that the batteries have
received a full charge. To
avoid premature charge
termination, allow the
batteries to cool to the same
temperature as the IMC
before inserting into the
battery slots.
Rapid Charging Mode (Default)
1. Insert batteries. For best performance insert
batteries from left to right. Note that each battery
slot will only support ONE battery at a time. Do
not attempt to insert more than one battery in any
given slot.
If a battery cannot be detected, make sure that the
battery is inserted all the way and try changing
the slot. If it still cannot be recognized, the battery
may not be accepting a charge and may need to be
replaced.
Figure 4 - Insert Batteries from Left to Right
2. When the battery is correctly inserted, charging
will commence for that slot. The IMC is equipped
with a four-level battery gauge which displays the
charging progress for each slot.

Soft Charging Mode
1. Remove all batteries from the IMC.
2. Insert one battery into the leftmost slot.
3. Within five seconds, press and hold the ‘SOFT’
button until the ‘Soft Charging’ symbol is displayed
on the LCD.
Figure 6 - Soft Charging Procedure
4. Insert the remaining batteries.
5. Soft Charging Mode will remain activated as long as
there are batteries in the charger (even if charging is
completed). The charger will reset to Rapid Charge
Mode (Soft Charging symbol disappears) when all
batteries are removed.
Battery Charging
Procedure - Soft
Note: Soft Charging is
activated for all battery
slots simultaneously and
cannot be activated for
each individual battery.

8Battery Conditioning
Procedure
Minelab supplied batteries do not require discharge
before recharging. However, if cycling of a set
of batteries is required, the IMC can be used to
automatically conduct a discharge-before-charge
cycle once initiated by the user. Conditioning a set of
batteries in an IMC will take up to 30 hours.
Ensure that the set-up procedure has been
completed.
1. Remove the charger from the carry bag.
2. Remove all batteries from the charger.
3. Insert ONE battery into the leftmost slot.
4. Within five seconds, press and hold the
‘CONDITION’ button until the ‘Condition’ symbol is
displayed on the LCD screen.
Figure 7 - Conditioning Mode Procedure
Note: Conditioning is
activated for all battery
slots simultaneously and
cannot be activated for
each individual battery.
Tip: If ‘Conditioning’
and ‘Soft Charging’ are
desired simultaneously,
insert the first battery and
press the ‘Soft Charging’
button first, followed
immediately by the
‘Conditioning’ button.
THIS CAN TAKE UP TO
60 HOURS FOR HIGH
CAPACITY BATTERIES.
