DTXP4130 DuraTrax IntelliPeak AC/DC Digital Pulse Charger
TECH NOTES
This is an IntelliPeak AC/DC Digital Pulse Charger for Charging/Discharging
Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) Battery Packs.
Note: Do Not Charge -OR- Discharge Battery Cells smaller than Sub-C Size
("Sub-C" is one size smaller than a "C" size).
FEATURES: Peak charges nickel-cadmium and Nickel-metal Hydride batteries using
two specialized peak charging technologies, plus discharging
and cycling features not commonly found in other chargers.
"Negative Delta V" peak detection for NiCds, plus advanced
"Zero Delta V" peak detection technology specifically for NiMHs,
providing full charges without overcharging.
Built-in Artificial Intelligence to eliminate false peaks.
Multi-function LCD, with selectable switch for viewing charge amps,
charge voltage, or battery capacity in milliamps. (see COMMENTS)
Auto-selects peak detection method by identifying cell chemistry.
Auto-identifies the quantity of cells being charged.
Computerized control, 8-bit 4MHz CPU with 8K ROM, 1K RAM,
1-channel 16-bit analog-to-digital converter.
High efficiency P-Channel MOSFET drive transistors.
11-15V DC input.
Incredibly small, detachable, 12 volt 7 amp AC power supply with
built-in cooling fan for at home use.
Output: 4-7 cells on DC, 4-8 cells on AC.
Adjustable fast charge current of 0.5-6.5 amps.
Pulsed fast charge, with 8-bit pulse width modulated current control
output.
100mA trickle charge.
Discharge voltage cutoff :2.6volts
10 and 2 amp fixed discharge rates, selectable by switch. Fixed
2.60V discharge cutoff voltage (see COMMENTS). Not designed for
discharging A or AA size (and smaller) cells (see COMMENTS).
Cycle functions: Select a single discharge/charge cycle for periodic
pack conditioning, or continuous "auto-repeat" cycles for reviving
batteries that have developed a memory, or for breaking in a new
pack.
Four multi-function, high intensity LED indicators. Status light
glows during charge and flashes when nearing peak.
Audible mode select tone signals for easy set-up.
Twin built-in miniature fans keep the charger cool, increasing
efficiency and lifespan.
Reverse polarity and overload protection.

COMMENTS:
LCD
Readout: The maximum reading the liquid crystal display (LCD) will show is
"1999". During discharge, any battery which is capable of
delivering over 1999mAh of capacity will cause the LCD reading to
reset to "0000" after showing "1999". In this case, the "0000"
reading should be treated as if it were saying "2000". The unit
will continue to measure discharge capacity until the battery is
discharged. When finished, simply add the final numerical reading
shown on the LCD to 2000 to achieve the final discharge reading.
So, if the LCD reaches "1999", resets to "0000" and continues
counting to "233", for example, add 2000+233 to get the final
discharge capacity of 2233mAh. Monitoring the LCD periodically
during discharge will be necessary. Failure to notice a "1999"
prior to observing a reading of "451", for example, will make it
impossible to know if the final discharge capacity was 451 or 2451.
These rules must be followed again for batteries having capacities
of 3000mAh or more, as this situation will occur again as the
battery reaches 3000mAh of discharge capacity.
Discharging cells smaller than sub-C size-
Do NOT Discharge Cells which are Smaller than Sub-C Size. This is
is to include A and AA size (and smaller) cells which are normally
installed inside radio transmitters and so on. The discharge
current rate of the IntelliPeak 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.
Fixed discharge cutoff voltage-
The IntelliPeak Charger has a fixed discharge cutoff voltage
setting of 2.60V. This cutoff voltage is not adjustable. If a
specific discharge cutoff value other than 2.60V is desired,
monitor the pack voltage during discharge with a separate voltmeter
(or the built-in LCD on the IntelliPeak Digital Pulse Charger) and
manually terminate discharge at such point as desired.
NiMH Battery Care and Handling: It is important not to allow NiMH
batteries to overheat while being charged. Heat can adversely
affect the performance of NiMH batteries. The Zero Delta V
technology is designed to allow for high rate, 6.5A fast charge
without adverse heating of the NiMH battery. 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.
WARNING: Do Not leave charger unattended during fast charge. If the
battery or charger becomes hot at any time, disconnect the battery
from the charger immediately.
-Do Not charge 4 or 5 cell batteries at a rate greater than 4.5 amps
as this could cause excessive heating in the charger itself.

Individual Charger Comparisons- Each one builds up to the next one:
-Pulse Charger: AC/DC input, 1 amp discharge rate, great for racers
and sport modelers alike.
-Mini Pulse Charger: Builds on the Pulse Charger's features with DC
input, detachable AC power supply...charger itself is very small,
great for portability, 2 amp discharge rate, 1 built-in cooling
fan. Note: This charger will only go down to a 1 amp charge
rate (The others chargers go down to .5 amps).
-Deluxe Pulse Charger: Adds to the Mini Pulse Charger's features
with DC input, detachable AC power supply. 2 and 10 amp discharge
rate (faster discharge ability). Negative Delta V (for NiCds)
and Zero DeltaV (for NiMHs) peak technologies, auto-selects.
