Thank you for purchasing SkyRC NC1500 AA/AAA Battery Charger & Analyzer.
Charging batteries is usually a primitive, boring and mundane activity, and it still is. What matters during the charging
activity, especially for AA/AAA NiMH battery charging? No doubt, accuracy and safety. The creation of NC1500 charger
not only arises out of need, but also from the desire to have a simple but safe and accurate charger for such battery.
NC1500 has 4 independent slots and supports AA/AAA NiMH batteries, offers maximum charge rate of 1500mA.

*At the start of a program, the device always performs a quick standard
test first in order to determine the internal battery resistance. Aged or
poor condition batteries have a higher IR and therefore heat up more
during charge or discharge. The values are estimates and will vary
depending on the state of the batteries and operation environment.

OPERATION
FEATURES
1. CHARGE
Charges your battery with selected constant current. Charging terminates when the battery is full or some other
termination criteria has been met. Useful when battery needs to be recharged. Should be used on batteries
known to be in good condition and which have been in continuous use.
Once the process is initiated, no other operations, like mode change, current selection etc. will be accepted.
Users, however, can click to check the battery real-time parameters like current, voltage, charge
capacity, internal resistance and elapsed time.
Insert a battery into slot.

After setting, the interface will stop flashing and CHARGE will initiate automatically 8 seconds later.
Press CURRENT
Displays Full when the CHARGE
process has finished.
This function allows you to charge a single AA or AAA or mixed with AA and AAA battery up to four at one time.
1) Connect the USB power adapter to the charger. A good USB power adapter with at least
2.1A(or 2100mA) output is required to power up NC1500.

Individual battery charging status
LCD display for easy reading.
Four buttons for easy operation.
Three modes of operation:
CHARGE, DISCHARGE and REFRESH.
Battery internal resistance detection
Powered by any USB adapter, smartphone charger
or power bank.
Maximum 1500mA charge rate for 1 or 2 batteries.
Termination methods:
- Individual minus delta voltage (-dV)
- Individual safety timer
- Temperature sensor
Trickle charge: to always have fully charged batteries
Maximum charging current can be set at 1500mA when only ONE or TWO batteries are charged.
The maximum charging current for THREE or FOUR batteries is 1000mA.
Trickle charging: After the battery is fully charged, the charger will give a small amount of current to
maintain the fully charged level.
