IMPORTANTWARNINGS
Disconnect the battery and remove input power from the charger immediately if the charger or battery
become hot!! Allow the charger or battery to cool down before reconnecting.
• NEVER attempt to charge incompatible types of rechargeable batteries as permanent damage to the battery and
charger could result.
• NEVER use automotive type battery chargers to power the charger.
• NEVER allow water, moisture or foreign objects into the charger.
• NEVER block the air intake holes or fan as this could cause the charger to overheat.
• NEVER attempt to use batteries with more cells or total voltage than listed in the specifications.
• NEVER leave the room where a battery is being charged or discharged.
• NEVER place the charger or battery on a flammable surface or near a flammable object while in use.Keep away from
carpets, wood, paper, plastic, cluttered workbenches, etc.
• NEVER overcharge batteries as permanent damage could result. Do not use a charge or discharge current rate
which exceeds the safe level of the battery. Do not attempt to charge or discharge a battery if it is hot.
• ALWAYS disconnect from power source when not in use.
• ALWAYS keep out of reach of children.
• ALWAYS connect the charge lead to the charger before connecting the battery to the lead. And ALWAYS disconnect the
battery from the charge lead BEFORE disconnecting the charge lead from the charger.Otherwise, if the ends of the charge
lead touch each other while the battery is still connected it will cause a severe and dangerous short-circuit condition.
GLOSSARY OFTERMS
Amps (A): The unit of measure for charge or discharge current.
Milli-amps (mA): A unit of measure for current, being amps (A) multiplied by 1000 and listed as “mA”. So 2.5A is the
same as 2500mA (2.5 x 1000). Or, to convert mA to amps, divide the mA number by 1000. So 25mA is the same as
0.025A (25 divided by 1000).
Capacity, milli-amp hours (mAh), and amp-hours (Ah): Charge energy stored by a battery is called capacity, which
is defined as how much current a battery can supply in one hour of time. Most hobby batteries are rated for capacity in
“mAh” or milli-amp hours. A 650mAh battery can deliver 650mA of current for one hour (650mA x 1hr = 650mAh).
A 3200mAh battery can deliver 3200mA (3.2A) of current for one hour (3200mA x 1hr = 3200mAh), etc. Very large
batteries, such as lead-acid field batteries, are usually rated in “Ah”or amp-hours. A “12V 7A” field battery can deliver
7 amps of current for one hour (7A x 1hr = 7Ah).
“C” rating: Capacity is also referred to as the “C” rating. Some battery suppliers recommend charge and discharge
currents based on the battery’s “C” rating. A battery’s “1C” current is the same number as the battery’s rated capacity
number, but noted in mA or amps. A 600mAh battery has a 1C current value of 600mA…a 3C current value of
(3 x 600mA) 1800mA or 1.8A.The 1C current value for a 3200mAh battery would be 3200mA (3.2A), etc.
INPUT POWER – CONNECTION, PROTECTIONS AND LIMITATIONS
AC Input: For indoor use, this charger includes a built-in switching AC power supply that delivers power by connecting
the AC power cord to a common 110V AC outlet.This built-in power supply is also compatible with 220V 50Hz sources
(220V input power cord not included).
DC Input: This charger can also be powered by a portable 12V DC power source for use at the field. It’s best to use a
clean DC power source whose output is filtered to remove unwanted electrical noise.Do NOT use an automobile battery
charger as a power source. On the left side of the charger, connect the DC power cord to a 12V DC power source.
Always match polarities (red lead to red “+” terminal, black lead to black “-” terminal). To utilize the charger’s absolute
maximum power capabilities the DC power source must be capable of delivering at least 12 amps while maintaining 12
volts DC.

4
For connection to power sources not having banana jacks, find a unique
set of alligator clip adapters included with the charger. A female banana
jack is built into the handle of each clip.Slide each clip onto the charger’s
input banana plugs (matching colors).Securely connect the charger’s red
clip to the positive (+) terminal on the power source, and the black clip to
the negative (-) terminal.
WARNING! Never accidentally short together the positive (+)
and negative (-) DC input connections when connected to 12V
DC power. Failure to do so could result in permanent damage
to the power source and the charger.
Triton2 EQ has a maximum overall power rating of 120 watts with DC
input, and 100 watts with AC input.If charging a battery with high voltage
at high current, or if the input voltage is low, the charger might limit the
output current as a result of the charger’s maximum power rating.This is normal. Refer to the “Maximum Power Chart”
included for more details about current limitations for higher voltage batteries.
The charger will be on at all times when connected to input power. Disconnect the charger from input power when not
in use.

DETERMINING BATTERYTYPE AND SPECIFICATIONS
IMPORTANT: It is always CRUCIAL to know your battery’s exact type, rated voltage and capacity!! To
avoid causing permanent damage to your battery, carefully read your battery’s label and/or instruction sheet or
consult your battery supplier and determine:
1. Type: Is the battery a nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-polymer (LiPo), lithium-ion (Li-
Ion), lithium ferrite nanophosphate (LiFe), or lead-acid (Pb)?
2. Rated capacity: This should be listed on the battery’s label in “mAh” (“milli-amp hours”). Capacity is also referred to
as the “C” rating. Charge and discharge currents are also expressed as a function of this “C” rating. For example, a
2100mAh battery would have a“1C”charge or discharge current rate of 2100mA or 2.1 amps.This battery’s 2C rating
would be (2.1 x 2) 4.2 amps, etc.
3. Rated voltage: NEVER guess the rated voltage of a lithium battery! If not printed on the battery’s outer label, consult
your battery supplier or determine pack voltage as follows:
a. NiMH and NiCd batteries: multiply the total number of cells in the pack by 1.20.
b. LiPo batteries: multiply the total number of cells in the pack by 3.70.
c. Li-Ion batteries: multiply the total number of cells in the pack by 3.60.
d. LiFe batteries (A123): multiply the total number of cells in the pack by 3.30.
e. Lead-acid (Pb): multiply the total number of cells in the battery by 2.0.
MENU STRUCTURE

5. STARTING CHARGE, DISCHARGE, OR CYCLE: Read the sections below for how to set values for the selected
battery type, and how to start charge, discharge, or a cycle.
CARE AND HANDLING INSTRUCTIONS FOR NiMH BATTERIES
• NEVER allow NiMH batteries to overheat, as this could adversely affect their performance or damage the cells.If this
happens, disconnect the battery from the charger immediately and allow to cool!
• NEVER deep cycle NiMH batteries as permanent damage could result.
• NEVER attempt to use the NiCd, Pb, or lithium functions with NiMH batteries.
• Store NiMH packs with some voltage remaining on the cells (refer to battery supplier).
CHARGING NiCd AND NiMH BATTERIES
1. In the Main Menu press BATT TYPE to find the “NiCd CHARGE” screen to charge a NiCd battery, or find the “NiMH
CHARGE” screen to charge a NiMH battery.
2. To change the charge current, press the dial to cause the value to flash. Turn the dial to find the desired charge
current. See the separate Triton2 EQ CURRENT CHART for recommended settings. A setting of “0.2A” is the same
as 200mA, “0.7A” is the same as 700mA, etc. Press the dial to confirm the selection. Note: Rotating the dial fully to
either direction will cause “auto” to show.See the “Notes” section below for details on the auto function.
3. To START PEAK CHARGE, press and hold the dial for 2 seconds.“BATTERY CHECK” will show while the charger
evaluates the condition of the battery. If the battery is ready, peak charge will start automatically at which time you’ll
see a screen like shown here.

Elapsedchargetime:Thisisthenumberof minutesthebattery has beenoncharge.
For a battery which previously has some charge, this number could be low. For a
battery which previously had little charge, this number should be larger.
WARNING! It is normal for NiCd and NiMH batteries to become warm during charge. Disconnect batteries
IMMEDIATELY if they become hot at any time! If batteries become overheated, it may be necessary to use a
lower charge current in the future. Never attempt to charge batteries at excessive rates as permanent damage
could result!
4. When peak charge is finished the screen will show “END” and tones will sound for 10 seconds. The charger will
automatically go to trickle charge at this time (see the notes section on the next page for details), but the battery
should now be ready for use. Other data measured during charge can be viewed in the DATA VIEW screens as
shown on page 16.

Notes for charging NiCd and NiMH batteries:
• Lower current means it takes longer to charge but it’s less stressful on the batteries, tends to result in more fully charged batteries, and helps
to maximize the battery’s lifespan.
• Larger “sub-C”size cells can handle peak charge currents up to 5.0 amps with little heat generation. Smaller “A” and “AA” cells overheat more
easily and should be charged at much lower currents. Even smaller “AAA” and “N” cells should be charged at lower rates. Refer to the Triton2
EQ CURRENT CHART for recommended charge currents.
• To keep NiCd batteries in good operating condition, it’s a good idea to properly discharge them before charging on a regular basis.
• NiMH batteries have a high self-discharge rate. Always recharge NiMH batteries just prior to use.
• The peak detection method is used to charge NiCd and NiMH batteries up to 95-98% full charge. A trickle charge current will automatically be
delivered after peak charge ends to help the battery safely reach 100% full charge.Trickle charge is applied only after an individual peak charge
(not after discharge or cycle), and will remain on until the pack is disconnected.Trickle current is automatically set, based on the fast charge
current setting as listed below:
Fast charge current Trickle current
0.0-0.9A 0mA
1.0-1.9A 50mA
2.0-2.9A 100mA
3.0-3.9A 150mA
4.0-4.9A 200mA
5.0-5.9A 250mA
6.0-7.0A 300mA
• Peak charge can be stopped manually by pressing the dial, or disconnecting the pack.
• In the “auto” current setting, the charger will automatically set the appropriate charge current based on the condition of the battery. It is NOT
recommended to use the “auto”function if charging smaller electric flight type NiCd / NiMH batteries (smaller than “AA” cells).
• A backup safety timer can be set to automatically stop charge if peak has not been detected in a certain period of time. See page 14.
DISCHARGING NiCd AND NiMH BATTERIES
1. To discharge a NiCd battery, press BATT TYPE to find the “NiCd CHARGE” screen. Turn the dial to find the “NiCd
DISCHARGE” screen, and skip to step 3.
2. To discharge a NiMH battery, press BATT TYPE to find the “NiMH CHARGE” screen.Turn the dial to find the “NiMH
DISCHARGE” screen.
3. Discharge current and cutoff voltage can be adjusted in the discharge screens.
a. Press the dial, then turn to adjust the discharge
current value. See the included CURRENT
CHART for recommended discharge current
settings. Note: Rotating the dial fully to either
direction will cause “auto” to show. See the
“Notes” section below for details on the auto
function.
b. Press the dial again to cause the cutoff voltage
to flash. This is the voltage of the entire pack
(not per cell) where discharge will end. See the
DISCHARGE CUTOFF VOLTAGES chart here
for recommended settings.
To measure how much TIME a battery can
realistically, safely power a transmitter or
receiver, it’s recommended to use the “1.1V per
cell” settings.
Otherwise, to measure a battery’s ability to hold
its manufacturer’s rated capacity, or to measure
how much time a battery can realistically
power an electric motor, use the “0.9V per cell”
settings.
4. To START DISCHARGE, press and hold the dial
for 2 seconds. “BATTERY CHECK” will show briefly
as the charger checks the condition of the battery.
Discharge will start automatically if the battery is in
suitable condition, at which time you’ll see a screen
like shown on the next page.

Discharge capacity: This is how much capacity (energy, in “mAh”) has been
delivered from the pack during discharge.For a battery which previously had little
charge, this number could be low. For a battery which previously had been fully
charged, this number should be high (ideally within 10% of the battery’s own
mAh rating).
Elapsed discharge time: This is the number of minutes the battery has been on
discharge. For a battery which previously had little charge, this number should be
low. For a battery which previously had been fully charged, this number should be
larger.
5. When discharge is finished, the screen will show“END”and tones will sound for 10 seconds.The battery can now be
re-charged, or disconnected. Other data measured during discharge can be viewed in the DATAVIEW screens (see
page 16).
Notes about discharging NiCd and NiMH batteries:
• Some transmitters might contain a diode which could prevent its battery from being discharged through the radio’s charge jack, causing a “No
battery” error to show. It’s best to remove the battery from the Tx and connect it directly to the charger for discharging (see page 5 for a list of
adapters).
• For more accurate discharge readings, it’s better to use a current which can discharge the pack in 1 or 2 hours.
• For packs having more than 6 volts, the actual amount of discharge current might automatically be limited due to the charger’s maximum
discharge power rating.See the included MAXIMUM POWER CHART for details.
• Compare the discharge capacity displayed to the capacity rating listed on the battery’s label. If a battery provides less than 70% of its rated
capacity it may need to be replaced. Additional cycles can be attempted to try and revive the battery, but if capacity measurements fail to
improve the battery should be replaced.
• Do not attempt to discharge cells to voltages lower than recommended.
• Discharge can be stopped manually by pressing MENU, or disconnecting the pack.
• In the “auto”current setting the charger will automatically set the appropriate discharge current based on the condition of the battery.The voltage
will automatically be set, based on the number of cells detected in the pack multiplied by 0.9V per cell. It is NOT recommended to use the “auto”
function if charging smaller electric flight type NiCd or NiMH batteries (smaller than “AA” cells).
• Discharging a battery can determine if it’s holding its rated capacity (see the CYCLING NiCd AND NIMH BATTERIES section). It can also
determine how much capacity remains in the battery after a flying session. This can help you gauge how much energy your flight system is
requiring from your battery.
CYCLING NiCd AND NiMH BATTERIES
Battery “cycling” is the process of fully charging then discharging a battery to a pre-determined cutoff point (or vise-
versa).Cycling is only recommended for NiCd and NiMH batteries (never for lithium or lead-acid batteries).This charger
can perform anywhere from one to ten cycles consecutively.
1. Decide if you want the battery to be discharged first (preferred if the battery is used often), or charged first (sometimes
preferred if the battery is new or has not been used for some time).
2. To cycle a NiCd battery, press BATT TYPE to find the “NiCd CHARGE” screen.Turn the dial to find either the “NiCd
CHG TO DSCH” or “NiCd DSCH TO CHG” screen (depending if you want to charge or discharge first) and skip to
step 4.
3. To cycle a NiMH battery, find the “NiMH CHARGE” screen.Turn the dial to find the “NiMH CHGTO DSCH” or “NiMH
DSCH TO CHG” screen (depending if you want to charge or discharge first).
4. Two current values will show – one for charge (Chg), and one for discharge (Dsch). Press the dial to cause the first
current value to flash.It’s very important to note whether this is the charge (Chg) or discharge (Dsch) current!
Turn the dial to find the desired current. Press the dial then turn to adjust the other current value.See the CURRENT
CHART for recommended charge and discharge currents.
5. To set the number of times the battery will be cycled consecutively, press the dial until “1X”starts to flash.Turn the dial
to adjust this setting as desired (1X is for one cycle, 9X is for nine cycles, etc.). Press the dial to confirm the setting.
6. To START CYCLING, press and hold the dial for 2 seconds.The “BATTERY CHECK..”message will show briefly, and
cycling will start if the battery is in suitable condition at which time you’ll see a screen like shown on the next page.

7. When all cycling is finished, “END” will show on-screen. To see measurements taken during cycling, see the DATA
VIEW screens (see page 16).
Notes for cycling NiCd and NiMH batteries:
• Periodic cycling of NiCd batteries (once every month or two) can be beneficial in keeping them in good operating condition. Excessive cycling
(more than once monthly) will unnecessarily shorten the lifespan of the battery.
• A short time delay can be set to occur between the charge/discharge functions to allow the battery to cool.This cycle time delay can be adjusted
from 1-60 minutes in the Setup Menu (see page 15).
• During cycle mode, the discharge cutoff voltage for NiCd and NiMH batteries is FIXED (not adjustable) at 0.9V per cell.
• See the notes sections for NiCd/NiMH charge and NiCd/NiMH discharge for detailed information regarding charges and discharges.
• Cell manufacturers note three main benefits of cycling NiCd and NiMH batteries:
1. Battery maintenance: NiCd batteries benefit the most from regular cycling to help keep them in good operating condition, and is
recommended once monthly. NiMH batteries do not require as much cycling.
2. Determining battery condition: NiCd and NiMH batteries are rated by how much charge energy or “capacity” they can store compared to
their rated capacity. A battery that can supply only a small fraction of its rated capacity is likely reaching the end of its useful life and may
need to be replaced.
3. Breaking-in batteries: new NiCd and NiMH batteries may need to be broken-in before they will perform to their specifications. Older
batteries which have been unused for an extended length of time may require to be broken-in again to regain their usefulness. Repeated
cycling is the best way to revive such batteries.
IMPORTANT CARE AND HANDLING INSTRUCTIONS FOR LITHIUM-POLYMER BATTERIES
WARNING!! NEVER ATTEMPT TO CARE FOR LITHIUM-POLYMER (LiPo) OR LITHIUM-ION (Li-Ion)
CELLS INTHE SAME WAY AS OTHER BATTERYTYPES! LiPo and Li-Ion cells are much more sensitive
and volatile than NiCd, NiMH or lead-acid batteries. Misuse and overcharge can quickly result in LiPo/Ion
cells getting hot and/or swelling, which could lead to VIOLENT EXPLOSION AND/OR FIRE and serious
personal injury and property damage.
• NEVER leave the room while charging or discharging lithium batteries!
• NEVER place lithium batteries on flammable surfaces during charge, such as wooden or plastic workbenches, paper,
carpet, cluttered areas, etc.
• NEVER attempt to use the NiCd, NiMH, or Pb functions with lithium batteries.
• NEVER continue to charge or use LiPo/Ion cells if they start to swell, become overly warm to the touch, or if they do
not charge within the specified charging time.Failure to follow this guideline could cause the battery to become hot,
and explode or ignite!!
• NEVER discharge Li-Ion cells lower than 2.5V per cell.
• ALWAYS have a “class D” fire extinguisher available when handling LiPo batteries.
• LiPo/Ion cells hold charge very well, and should not be trickle charged or cycled.
• LiPo/Ion cells should be charged about once per year at a minimum to prevent over-discharge.
• LiPo/Ion batteries should be stored with about 30%-50% of capacity.
• If LiPo/Ion cells leak fluid, rinse the affected area well with water and seek immediate medical care.
