Introduction:

Thank you for choosing the Promax Black Widow Elite AC/DC Peak-Detection
charger. This charger is designed to charge 1 (1.2V) to 16 (19.2V)
Nickel-Cadmium or Nickel-Metal Hydride cells ranging from 50mAH and
higher. This charger features an easy to read LCD screen that displays
battery information during the charging process. The charger also features
a one-touch discharger that can be operated in either automatic mode or
"forced" mode. An internal cooling fan is featured to keep the charger cool.
Please read through this operations sheet completely before using your
charger for the first time.

Please Read and Understand the Following Warnings:

●

This charger is designed to charge 1.2V - 19.2V NiCD and NiMH battery
packs/cells ONLY. Do not attempt to charge any other type of battery, such
as gel cell, lead-acid, Lithium or Alkaline batteries.

●

Never connect the AC power and the DC power input cords at the same
time and never allow the 12V DC alligator clips to touch or short out.

●

When the charger is connected to an automotive battery (12V DC power
source) do not start the automobile’s engine. The engine can be running
during the charge process, but starting or turning off the engine during the
charge process can damage the charger and/or your battery pack.

●

Do not allow children to use the charger without adult supervision.

●

Never leave the charger connected to a power source when not in use.

●

Never leave the charger unattended when the charger is in use.

●

Never place the charger on a carpeted surface during use.

●

Always disconnect the battery pack from the charger if the battery pack
becomes unusually warm or hot.

●

Avoid using the charger in direct sunlight. Direct sunlight can cause the
charger to overheat and/or the LCD screen to be damaged.

●

Always check the battery pack's polarity and condition before connecting it
to the charger.

●

If using the charger to charge Tx battery packs, you must remove the
battery pack from the Tx first. Do not attempt to charge the battery pack
while still in the Tx.

●

Always allow the battery pack to cool before recharging it.

Black Widow Elite Safety Features:

●

If the battery pack polarity is reversed or if the battery pack has a short
circuit, the charger will shut off and the LEDs on the front of the charger will
blink rapidly. If this happens, unplug the battery pack from the charger
and double-check all wires for polarity and short circuits before reattaching
the battery pack to the charger.

●

The charger features a manually selectable maximum charge time that
can be set to prevent your battery from overcharging. If the battery pack
malfunctions or misses the “peak," the timer will automatically stop the
charging process after the elapsed time you've input into the charger.

Connecting Your Black Widow Elite Charger:

●

Plug the desired input cord into the back of the charger (either 12V DC or
110V AC), then plug the input cord into the power source. The charger will
chime and the CHARGE light will begin to blink. If you're charging more
than 8 cells, you will need to connect the charger to a 12V DC power source.

WARNING Never plug the charger into a 220V power source and never
connect the charger to a 12V DC and a 110V AC power source at the same
time. Only use one desired power source at a time. If connecting the charger
to a 12V DC power source, make sure to attach the red alligator clip to the
positive terminal and the black alligator clip to the negative terminal.

●

Plug the banana plugs on the output cord into the front of the charger,

making sure that the polarity is
correct (red to red and black to
black), then connect your battery
to the output cord.

IMPORTANT If the connector on
your battery is different from the
connector on the output cord, you

will need to change the connector
on the output cord. If you do, double-check that the polarity is correct when
you install your new connector.

●

When you connect your battery, the CHARGE light will continue to blink and
the LCD screen will show the current voltage of the battery as indicated by the
"V" on the LCD screen. If no battery is connected, the voltage will read "0.00".

Using the Black Widow Elite Charger:

To charge your battery, you must follow the steps below:

1) Choose a Cell Type -Either NiMH or NiCD

2) Choose the Number of Cells

3) Choose a Charge Rate

4) Set the Safe Timer

5) Begin the Discharge/Charge Cycle or Force Charge w/o Discharge

●

Next, choose the number of cells by briefly pressing the INC or DEC

buttons. The cell count should be
the same as the number of cells in
your battery as indicated on the
LCD screen.

WARNING The cell count you
input into the charger MUST match
the number of cells in your battery.
If not, the battery will not charge

properly and damage to your battery and/or charger could occur.

●

After selecting the cell type and cell count, briefly press the MODE button

once to enter the CHARGE
CURRENT screen, as indicated by
"Amps" on the LCD screen.

●

Select the charge rate by briefly
pressing the INC or DEC buttons
until the desired charge rate is
selected as indicated on the LCD
screen. Notice that the charge rate

can be adjusted in 50mA increments from 100mA - 6A. The maximum
charge rate for NiMH cells is 5A. See the table below for recommended
charge rates:

Recommended Charge Rates

We recommend choosing a charge rate for NiMH batteries that is close to
the batteries' rated mAH capacity (e.g., charge a 2000mAH NiMH battery at
no more than 2 amps). For NiCD batteries, we recommend choosing a charge
rate that is 1-3 times the batteries' rated mAH capacity (e.g., charge a
1400mAH NiCD battery at 2-4 amps).

NiCD Charge Rates NiMH Charge Rates

100-900mAH - 100mA-900mA 100-900mAH -- 100mA-900mA

1000mAH --- 1A -3 A 1000mAH ---1A

1200mAH --- 2A - 3A 1200mAH --- 1A

1400mAH --- 2A - 4A 1400mAH --- 1A

1600mAH --- 2A - 5A 1600mAH --- 1A - 2A

1800mAH --- 2A - 5A 1800mAH --- 1A - 2A

2000mAH --- 2A - 6A 2000mAH --- 2A

2400mAH --- 3A - 6A 2400mAH --- 2A

2800mAH --- 3A - 6A 2800mAH --- 3A

3000mAH --- 3A - 6A 3000mAH --- 3A

The maximum

charge rate for

NiMH cells

is 5A

IMPORTANT The charger will only charge 1-8 cells using a 110V
AC or 12V DC power source. To charge 9-16 cells, you must use a
12V DC power source only.

●

To choose the cell type, from the VOLTAGE screen briefly press the MODE

button 4 times to enter the CELL
TYPE/CELL COUNT screen as
indicated by "CELLS" on the LCD
screen.

●

Now, choose the cell type (either
NiMH or NiCD) by pressing and
holding the MODE button for 3
seconds. The cell type will change

as indicated by "Cd" or "H" on the LCD screen. If your battery has NiCD
cells, choose the "Cd" cell type. If your battery has NiMH cells, choose the
"H" cell type.

WARNING Never charge a NiMH battery using the NiCD cell type and never
charge a NiCD battery using the NiMH cell type. Never attempt to charge
any other type of cell, such as LiPO, gel cell, lead acid or Alkaline.

Sample average charge time for a 1600mAH battery charged at:

1Amp is 96 minutes

2Amps is 48 minutes

4Amps is 24 minutes

1600/4000=0.4x60=24 Minutes

1000mA in 1A

IMPORTANT Batteries may be charged at different rates depending on the

manufacturer’s suggestions. The table above is for general reference only
and errs on the side of caution.

●

After setting the charge rate, briefly press the MODE button once to enter

the SAFE TIMER screen as
indicated by "SAFE TIME" on the
LCD screen.

●

Set the SAFE TIMER by briefly
pressing the INC or DEC buttons
to increase or decrease the
internal timer. The SAFE TIMER
should be set slightly higher than

the estimated charge time of the battery. The charge time can be estimated
by calculating the mAH rating of the battery and the charge rate. As an
