Novak Millennium Charger - Manual (Page 2)

After starting charge, the battery and connections are analyzed. If needed,
the Millennium will attempt to condition the battery with a low-level
trickle charge to bring up individual cell voltages so that successful charging
can occur without reversing a cell. To stop charge, push BACK button.
During the charge, the LCD cycles through three screens of charge infor-
mation, including: {charge time & pack voltage}, {# of cells & delta-peak
value}, and {charge mode, charge current, charge time, & pack voltage}.
At the end of charge, the Millennium will cycle between the charge history
screen and a Charge Complete screen accompanied by an audible alert.
THE CHARGING PROCESS
From the Start screen, push the down (B) button once, or the up (C)
button five times to go to the Charge Mode option screen.
Push the ENTER button from the Charge Mode option screen. You can
now use the down (B) and up (C) buttons to change the Millennium’s
method of charging. The choices are as follows:
T T T
T T T

Push ENTER when the desired charge method screen is visible.
After entering into this charge parameter adjustment level of the software,
the screen will indicate that you can change the value of the active
parameter by underlining the value. Use the down (B) and up (C) buttons
to adjust the parameter. Press ENTER to activate the next parameter on
the screen, and again use the down (B) and up (C) buttons to adjust.
In each charge mode (Linear, Reverse Pulse, and Ni-MH), you can adjust the
number of cells in the battery pack (4-8), and the charge current (amps).
Ni-Cd Linear Charging Mode
This method is a linear charge with adjustable current between 0.5 and
7.0 amps, and has an adjustable trickle charge (0.1-0.4 amp) option that
follows the peak of the charge and can be turned on or off.
In the Linear charge mode, pressing ENTER after adjusting the charge
current will bring up the trickle charge option. Use the down (B) or up
(C) button to change trickle charge from on to off. Press ENTER again to
activate the trickle charge current, and again use the down (B) and up
(C) buttons to adjust. Press ENTER when finished. You will automatically
jump to the Start option screen to begin charging––Press ENTER to start.
Ni-Cd Reverse Pulse Charging Mode
This method is also a linear charge with adjustable current between 0.5
and 7.0 amps, however this method uses a short pulse of discharge or
“Reverse Pulse” once per second for an adjustable duration of 5 to 20
milliseconds. There is no trickle charge option with this charge method.
In the Reverse Pulse charge mode, after you adjust the number of cells
and charge current just as in the Linear mode above, pressing ENTER will
activate the Pulse parameter. Use the down (B) or up (C) buttons to
adjust the pulse duration. Press ENTER when finished to jump to the Start
option screen to begin charging––Press ENTER to start charging.
Ni-MH Charging Mode {See ‘Recommended Settings’ for Sub-C Ni-MH cells}
This method is a linear charge for small (A & AA cells) Ni-MH batteries.
Charge current is adjustable from 0.5 and 1.5A.
In this mode, adjust the number of cells using the down (B) or up (C)
buttons, press ENTER, then adjust the charge current. Press ENTER when
finished adjusting the charge current to jump to the Start option screen
to begin charging––Press ENTER to start charging.
CHARGE MODE SELECTION

Charge Mode
From the Start screen, push the up (C) button four times to go to the
View Charge Info option screen, or once more from the Volt Threshold
screen. Remember that these screens are on a loop, and you can go either
direction to get back to a desired option screen.
The View Charge Info option gives you detailed information about the
last battery pack that was charged. This information can prove helpful in
comparing battery packs, and also tracking the performance of your packs.
To view the charge history, push the ENTER button from the View Charge
Info option screen. If the Millennium has never been used, or it has been
reset to factory defaults, all values will be zero.
The display shows the battery’s peak voltage,
the time in seconds to charge the pack, the
battery pack’s capacity in milliamp hours, and
the pack’s energy measured in joules. The calculations used are:
Capacity (mAh) = {Charge Current (milliamps)} x {Charge Time (hours)}
Energy (J) = {Charge Current} x {Charge Time} x {Average Charge Voltage}

TROUBLE-SHOOTING GUIDE
This section lists the messages that may appear on the Millennium’s display,
and the probable causes and solutions. If you are unable to solve your
problem, check our website or call our Customer Service Department.
• Battery voltage too low to begin charge process.
• One or more cells shorted.
• Number of cells set too high.
• Output leads/alligator clips are shorted.
• Battery pack connected backwards.
• Charging attempted with no battery connected.
• Charging attempted with no power source.
• Battery pack has open cell or bad connection––
Check battery pack and cells.
• Input power source disconnected while charging.
• Battery disconnected while charging.
• Battery voltage close to power source voltage––
Increase input power source voltage.
• Output leads un-shorted during conditioning.
• Output leads un-shorted during conditioning,
then re-shorted––Check output leads for short.
• Output leads shorted during charging––Check
output leads for short.
• Number of cells set too high.
• After conditioning, battery voltage still too low
to begin charge process––Try new battery.
• Internal temperature above 203
°
F––Check intake
grill for blockage. Will go to Start screen when cool.
• No Alarm or Button tone is heard––Alarm or
Button tone is set too low. Increase tone setting.
***To reset all factory defaults and settings, hold down the BACK button during the
Millennium’s start-up screen until “Factory Settings Restored” is displayed.

DISCHARGING
Ni-Cd To maintain capacity, discharge every charge cycle with 30 ohm/10
watt resistor across terminals. Remove when resistor cools to room temp.
Ni-MH Do not deep-discharge (No discharge trays, resistors, or light bulbs).
LINEAR CHARGING MODE
Ni-Cd Charge at 3.5-4.5 amps for Sub-C & D cells, and 0.5-1.0 amp for AA’s.
Battery makers specify the charge current at no more than 2.5 times the
capacity (2.5 x 2000mAh = 5.0A) & twice capacity for D cells.
Ni-MH Charge Sub-C Ni-MH cells at 4.0-5.5 amps and trickle charge OFF.
REVERSE-PULSE CHARGING MODE
Ni-Cd A rev. pulse duration of 12ms will help enhance run times & increase
average discharge voltage by lowering battery’s internal resistance. Use
5-9ms for small (A & AA) cells & 10-20ms for large (Sub-C & D) cells.
Ni-MH Not recommended.
Ni-MH CHARGING MODE
Ni-Cd Not recommended.
Ni-MH Charge cells smaller than Sub-C size at 0.5-0.8 amp.
Not recommended for Sub-C and larger cells
RE-PEAKING
Ni-Cd Wait a short time after the initial charge to allow individual cells to
equalize, then re-peak the pack to bring all cells up together.
Ni-MH Not recommended. Use Ni-MH cells immediately after inital charge.
VOLTAGE THRESHOLD
Ni-Cd Set delta-peak (Volt Threshold) to 12 mV/cell for Linear charging, and
14-18 mV/cell for Reverse Pulse. Too-high of a delta value will overheat
batteries and decrease the battery life.
Ni-MH Set delta-peak to 4 mV/cell (Millennium V.1.20/newer) to avoid overheating.
Millenniums with no version # at start-up, set delta-peak to 8 mV/cell (min).
