Unlike most other chargers, the
IntelliPeak Pulse Charger is
capable of charging both nickel-

cadmium (NiCd) and nickel­metal hydride (NiMH) battery chemistries, as
identified by this symbol. Look exclusively for
battery chargers with this symbol to handle both
NiCd and NiMH charging needs.

While similar in appearance to sub-C NiCd
batteries, NiMH batteries have a different internal
chemistry and require a different charging method.

It is important not to allow NiMH batteries to
overheat while being charged. Heat can

adversely affect the performance of NiMH
batteries. When charging NiMH batteries with the
IntelliPeak Pulse Charger, do not adjust the PEAK
CHARGE AMPS adjustment knob above 3.0
amps. Charging at a higher amperage will heat up
the batteries and could cause permanent damage.
If overheating is observed, disconnect the battery
from the charger immediately, and reduce the
charge rate for future charging needs. Also, do not
deep cycle NiMH batteries. Permanent damage
could result. Store NiMH packs with some voltage
remaining on the cells. Use a NiMH battery pack
no more than three cycles per day, with a two to
three hour break in-between for cooling. More
frequent use is likely to overheat the pack.

If using a DC power supply or 12V DC battery for
input power, connect the DC adapter (included) to
the lead exiting the rear of the charger. Attach the
red alligator clip to the positive (+) terminal on the
power supply, and the black alligator clip to the
negative (-) terminal. It’s best to use a clean DC
power source whose output is filtered to remove
unwanted electrical noise. Disconnect the DC

input

adapter cord from the charger when not in use.

If using 110V AC for input power, connect the black
AC plug to a regular 110V wall outlet. Do not
connect the DC input leads to any power source
simultaneously with AC input, as permanent
damage to your charger may result.

The IntelliPeak Pulse Charger is fuse protected
from current overload. Only replace the glass fuse
with one of the same rating (250V/3A) and size
(5 x 20mm). CAUTION: Disconnect the charger

from the AC power source and the load battery
from the charger before replacing the fuse.

The output lead (included) has a standard style
connector at one end, with the opposite wire ends
stripped so a small portion of bare wire is showing.
Insert the red, positive (+) wire into the red spring
loaded terminal on the front of the charger. Install
the black, negative (-) wire into the black spring
loaded terminal. These terminals allow virtually
any other charge leads to easily be connected to
the charger if so desired. CAUTION: Make sure

wire strands never make connection between
the red and black terminals! Failure to do so

could result in a short circuit condition, causing the
fuse to blow or permanent damage to the charger
and/or battery.

The IntelliPeak Pulse Charger offers a slow
100mA trickle charge rate for charging a new
battery or topping off a previously charged battery.
Connect the battery to the charge lead on the front
of the charger. The green SLOW CHARGE LED
should automatically begin to flash, indicating
trickle charge is in progress. A 1500mAh battery
should reach full charge in approximately 15 hours
using this charge method.

This unit has a high-rate fast charge to recharge a
partially discharged battery, with circuitry designed
to monitor pack voltage and automatically
terminate fast charge when full charge is reached.
Select the desired charge rate using the PEAK
CHARGE AMPS adjustment knob. Connect the
battery to the charge lead on the front of the
charger. The green SLOW CHARGE LED should
automatically begin to flash, indicating trickle
charge is in progress. Push the MODE SELECT
button once to start peak charging. The red PEAK
CHARGE LED should light, and the charger will
beep once to confirm peak charge is in progress.
When this LED begins to flash the battery is
approaching peak charge. This should soon be
followed by occasional flashing of the STATUS
LED, where each flash represents instantaneous
moments when actual battery voltage is starting to
decline, thus indicating the battery has reached
peak and the charger will soon return to slow
charge automatically.

WARNING: Do not leave charger unattended
during fast charge. If the battery or charger
become hot at any time, disconnect the battery
from the charger immediately! Failure to do so

may cause permanent damage to the charger and
battery, and may cause bodily harm. Reduce the
charge rate for future charging needs.

SPECIAL FEATURES

Congratulations on your purchase of the IntelliPeak™Pulse Charger by DuraTrax®! A step up from traditional “sport” chargers, the IntelliPeak Pulse Charger’s
many exceptional features combined with a very easy-to-use format make it attractive to competition-level racers and sport users alike.

Do NOT charge 4 or 5 cell batteries at a rate
greater than 4.5A, as this could cause excessive
heating in the charger itself.

Discharging removes charge from a battery for
storage or conditioning purposes. Connect the
battery to the lead on the front of the charger. Push
and hold the MODE SELECT button for two
seconds. The charger will beep two times, and the
amber DISCHARGE LED will light, confirming
discharge is in progress at a fixed rate of 1 amp.
When the battery is finished discharging, the

charger

will automatically switch to slow charge mode.

The IntelliPeak Charger has a fixed, non-

adjustable
discharge cutoff voltage setting of 2.60V. If a
specific discharge cutoff value other than 2.60V is
desired, monitor the pack voltage during discharge
with a seperate voltmeter and manually terminate
discharge at such point as desired. This step must
be followed during all cycling functions as well if a
different cutoff voltage is desired.

WARNING: Do NOT discharge cells which are
smaller than sub-C size. The discharge current

rate of the IntelliPeak is too high for smaller cells
such as A, AA, and AAA size, in addition to the
wiring used to assemble such packs. Failing to
avoid this will likely cause permanent damage to
the cells and/or wiring in the battery packs, and
possibly the equipment in which the battery is
installed.

Use the single cycling feature to conduct a single
discharge/charge cycle for periodic pack
conditioning of regularly used batteries. Select the
desired charge rate using the PEAK CHARGE
AMPS adjustment knob. Then, connect the battery
to the charge lead on the front of the charger. Push
the MODE SELECT button twice. The amber
DISCHARGE LED will light and the charger will
beep three times to confirm single cycling is in
progress. When discharge is complete, it will
automatically switch to peak charging, confirmed
by the red PEAK CHARGE LED and a single
beep. This LED will flash when the battery nears
peak charge, after which the charger will
automatically return to slow charge as indicated by
the flashing green SLOW CHARGE LED.

Auto-repeat cycling lets you conduct repeated
discharge/charge cycles for deep pack
conditioning to break in new packs or revive older
or unused packs which may have developed
memory. Select the desired charge rate using the
PEAK CHARGE AMPS adjustment knob. Then,
connect the battery to the charge lead on the front
of the charger. Push the MODE SELECT button
twice and hold it down for two seconds. The amber
DISCHARGE LED will light and the charger will
beep four times to confirm auto-repeat cycling is in
progress. After the battery has finished
discharging it will automatically switch to peak
charge mode, confirmed by the red PEAK
CHARGE LED and a single beep. When this LED
begins to flash, the battery is approaching peak
charge. This should soon be followed by
occasional flashing of the STATUS LED, where

each flash represents instantaneous moments
when actual battery voltage is starting to decline,
thus indicating the battery has reached peak and
the charger will soon return to slow charge
automatically. Once peak charge has completed,
the charger will automatically repeat this entire
discharge/charge process. To end this function,
the user must push the MODE SELECT button or
disconnect battery from the charger.

To discharge the battery for storage, allow the
battery to cycle the desired amount of times and
then push the MODE SELECT button until the
orange DISCHARGE LED lights. This will start
discharge mode only. To peak charge the battery,
wait until the last desired cycle is over and then
push the MODE SELECT button until the red
PEAK CHARGE LED lights.

The IntelliPeak Pulse Charger is capable of
charging 9.6V transmitter batteries. This is best
accomplished when using 110V AC input power, or
DC input power of greater than 12V but less than
15V. Connect the appropriate adapter (not
included) into the spring terminals on the front of
the charger. CAUTION: Failure to recognize

proper polarities will cause permanent damage
to the battery and/or radio! Turn the PEAK

CHARGE AMPS adjustment knob down to 0.5
amps to allow the batteries to peak charge.
Charging at a higher amperage can cause
permanent damage to the transmitter batteries. Do
not allow standard capacity TX batteries to remain
in slow charge mode in excess of 1 hour after peak
charge has been reached, as overheating of the
battery might occur. Note: If your transmitter has

a diode in the charge circuit, it may be
necessary to remove this diode to allow your
transmitter to receive a full charge with this
IntelliPeak charger. In addition, the battery will
NOT accept a discharge with the diode in the
circuit. Removal of the diode will allow a full
charge and discharge.

WARNING: Do NOT discharge transmitter
batteries with the IntelliPeak Charger. The

discharge current rate is too high for such smaller
cells and the wiring which is used to assemble
such packs. Failing to avoid this will likely cause
permanent damage to the cells and/or wiring in the
battery packs, and possibly the equipment in
which the battery is installed.
