• NEVER place the charger or battery on a fl ammable surface or near a fl ammable object while in use. Keep away from
carpets, 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 OF TERMS
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 defi ned 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 fi eld batteries, are usually rated in “Ah” or amp-hours. A “12V 7A” fi eld 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 value 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. 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 included 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 fi eld. It’s best to use a
clean DC power source whose output is fi ltered 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’s alligator clips directly to the
output terminals on the 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 7.2A while maintaining 11 volts DC.
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.
TritonEQ has a maximum overall power rating of 63 watts with DC input, and 50 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.
The charger will be on at all times when connected to input power. Disconnect the charger from input power when not
in use.
