Congratulations on your choice of SkyRC NC2500 Pro Charger!
NC2500 Pro is a six-channel charger for AA/AAA NiMH/NiCD Batteries
with four working modes of Charge, Discharge, Refresh and Break-
in. You can set the proper working current based on different battery
capacities, and the current is adjustable, ranging from 0.1A to 2.5A.
With the wide-viewing LCD screen, NC2500 Pro displays current,
capacity, voltage, elapsed time, and working mode at a glance.
NC2500 Pro features battery internal resistance detection, QC3.0,
motor run-in, and the firmware is upgradable.

Never charge batteries other than NiMH or NiCD. Please read the battery's
manual to ensure it can accept the programmed charge/discharge rates.
Never expose the unit to rain or moisture to avoid fire.
Never use the charger if it appears damaged.
Do place the battery with a positive terminal facing the top. Wrong polarity
may cause fire or explosion.
Do not allow the unit to expose to direct sunlight. Operate in a well-ventilated
area. Do not place the charger on the carpet.
Never allow the battery terminals to become shorted.
Please use the standard AC adaptor included in the package.
The batteries may become hot during charging/discharging(especially at a
high chosen current).
Please use caution while removing batteries after charging/discharging.
Remove all the batteries while not in use.
Four working modes of Charge, Discharge, Refresh and Break-In.
Step charge mode to set the proper current for each charging step.
Adjust current automatically based on the detected battery resistance
Six independent slots to charge six cells simultaneously.
Six LED indicators make working status intuitive.
Set up once, applied to all of the six ports.
Intuitive interface with independent display for each slot.
Information at a glance: Current, Voltage, Capacity, Elapsed time, and
Working mode.

Charge Rate
The internal resistance of the battery usually increases as it is used.
When the battery is used for a long time, its internal resistance will
increase. The internal resistance consumes part of the electric energy
during charging and causes the battery to heat up simultaneously.
We deploy an innovative FlexiPulse algorithm for internal resistance
detection. Once a high internal resistance is detected, the charge
current will automatically decrease to reduce the overall heating to
protect the battery.
Please use the Refresh mode when determining the battery capacity.

What is the "C" of a Battery?
Choose the Right Charge & Discharge Rate.
“C” stands for the battery capacity, and the number preceding it is
the fraction of the battery capacity. For example, 0.3C means 0.3
times the capacity for the battery. For a 2400mAh battery, 0.3C
would be 0.3 x 2400mAh = 720mA.
Charge at a rate lower than 0.3C and higher than 1.0C is not
recommended. Charging too slow may affect the charger
termination properly. Charging too fast may cause the battery to
overheat and shorten its lifespan.
Generally speaking, a lower charging rate can prolong the battery
lifespan while charging time will be longer. A higher charging rate
makes charging fast but with the battery heat-up, which will shorten
its lifespan.
Discharge at a rate above 1.0C is not recommended.
Charge/Discharge Rate Reference
BATTERY KNOWLEDGE
What is the Meaning of “mAh” on Rechargeable Batteries?
mAh means milliamp Hour and is a unit that measures (electric)
power over time. It is commonly used to measure the energy
capacity of a battery. In general, the more mAh and the longer the
battery capacity or battery life.
Battery Capacity mAh (milliampere/hour) = discharge (milliampere)
x discharging time (hour)
For example, if you insert a 2400mAh battery into an appliance that
consumes 50 milliampere current continuously, the operating time
will be around 48 hours.

Battery Matching
Most electronic devices usually require two or more batteries to be
used together. In this circumstance, the worst battery will limit the
device's overall performance.
Battery matching means grouping batteries by a similar capacity to
maximize efficiency. Detect the battery capacity with the Refresh
mode to group batteries easily.

Battery Formatting
New batteries and those stored for more than three months become
chemically deactivated. With BREAK-IN mode, NC2500 Pro will
charge & discharge the battery with a small charge and discharge
rate in a charge-discharge-charge sequence. This process may
need to repeat two or three times for complete formatting.
This charger comes with four working modes, each of which will be
used under the different situations as below.

Charge the battery with a programmable charge rate.
Discharge the battery with a programmable discharge rate.
Determine the battery's performance based on the actual
capacity it can hold. It's applicable for batteries stored for
more than two weeks and less than three months or for
batteries that are not performing well.
Applicable for new batteries and those stored for more
than three months. The BREAK-IN mode is to activate the
battery with a small charge and discharge rate in a charge-
discharge-charge sequence.
