SKY RC NC2200 AA/AAA Charger

This SkyRC NC2200 AA/AAA battery charger-analyzer charges up to 4 batteries at once, so you can quickly power your electronic devices. The visual charging status keeps you informed on when your batteries are ready for use.
It can handle 1 to 4 AA and AAA NiMH/NiCD rechargeable batteries via four independent charging slots with its respective interface.
With the wide-viewing VA screen, the charger displays Current, Capacity, Internal Resistance, Voltage, Elapsed Time, and working mode at a glance. Meanwhile, the charging graph and firmware upgrading can be accessible with the SkyCharger app if you connect the optional Bluetooth Dongle.

NC2200 on a Power Chip.
The Cortex-M3 processor is specifically developed for high-performance, cost-effective platforms for various devices, including microcontrollers, automotive body systems, industrial control systems, and wireless networking and sensors.

Thanks to Cortex-M3 by ARM, NC2200 can complete real-time acquisition of battery voltage and current, and the charging process under intelligent control. It can automatically calculate the remaining charging time of the battery and adjust the parameters. System management circuit also has a protective function, which can prevent damage to the battery from overcharge and overtime.

5 Modes to Stay Charged & Healthy
NC2200 comes with five operation modes: Turbo(fast charge), Charge, Discharge, Refresh & Analyze and Break-in. With these five modes, you can charge, optimize your battery, and even you can rescue the battery from dying.

Overheating is Prevented
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 when charging and causes the battery to heat up simultaneously.
SkyRC deploys an innovative FlexiPulse algorithm for internal resistance detection in this charger.
Once a high internal resistance is detected, the charge current will automatically decrease to reduce the overall heating and protect the battery.

Stunning Display:
Deep Blacks and Bright Whites
In high contrast black and white, current, capacity, internal resistance, voltage, elapsed time and working mode are displayed stunningly at a glance.

Rescue a Battery to Further Life! Any useless battery in your drawer?
With NC2200, users can try to rescue useless or none-performing-well batteries. Regardless that it is against the law to dispose of these batteries improperly, you have some chance to save the almost dead batteries.
After trying all the modes as in the manual, refer to the battery rescue steps as simple as 1-2-3:
1. Use the REFRESH & ANALYZE mode once to three times.
2. Change to BREAK-IN mode if the capacity is still low.
3. If the second steps can improve the battery capacity by more than 10%, please try BREAK-IN mode once to three times again. If there are no significant improvements and the actual battery capacity is less than 60% of its rated capacity. The battery would probably be at the end of its life and needs to be replaced.
