NC1500

AA/AAA NiMH Battery Charger & Analyzer

INTRODUCTION

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.

OPERATION

1. CHARGE

This function allows you to charge a single AA or AAA or mixed with AA and AAA battery up to four at one time. 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.

Note: As the 4 slots are independent from each other, we only take slot 1 as an example for below operation mode descriptions.

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.

Insert a battery into slot.

*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.

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

Press to select charge current (200, 500, 700, 1000, 1500mA),

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.

CHARGE

After setting, the interface will stop flashing and CHARGE will initiate automatically 8 seconds later.

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.

Displays Full when the CHARGE process has finished.

Trickle charging: After the battery is fully charged, the charger will give a small amount of current to maintain the fully charged level.

3. REFRESH

First charges the battery, rest for one hour, discharges, rest, then recharges again. This function reduces the memory effect and re-activates rechargeable batteries that have been unused for a long period of time. Also useful when the battery capacity needs to be determined.

What is memory effect: It describes the situation in which rechargeable batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. REFRESH may bring the rechargeable battery back to optimum condition.

Insert a battery into slot.

Press to select REFRESH mode;

Press to select charge current (200, 500, 700, 1000, 1500mA). Discharge current will be half of charging current selected.
