Product overview
The SkyRC NC2200 Charger, product code SK-100181, charges and analyzes cylindrical rechargeable batteries. Four independent slots each mechanically accept AA or AAA cells, accommodating one to four NiMH/NiCD batteries. Its enclosure measures 112.1*108*62 mm and weighs 370g. The VA display shows current, capacity, internal resistance, voltage, elapsed time and operating mode; individual slot LEDs show red during charging and green at completion. The supplied configuration includes the charger, instruction manual and 12V/2A power adaptor. An optional Bluetooth dongle enables charging graphs and firmware upgrades through the SkyRC app.
Five operating modes cover Turbo, Charge, Discharge, Refresh & Analyze, and Break-in. Charge current spans 0.2-2.2A and discharge current spans 0.1-1.0A, both adjustable in 0.1A increments. Supported capacity is 500-3200mAh, with 3200mAh capacity protection, 0.9V discharge termination and a 5mV negative delta voltage setting. Input is DC 12V/2.0A. Turbo delivers 2.2A for batteries in good condition; resistance above 40mΩ stops operation and triggers flashing indicators. High internal resistance also prompts automatic charge-current reduction to limit heating, while the management circuit provides overcharge and overtime protection.
Refresh & Analyze assesses actual capacity for batteries stored more than two weeks and less than three months, or performing poorly; Refresh also supports matching cells by capacity. Break-in uses a low-rate charge-discharge-charge sequence for new batteries or those stored more than three months. Following rescue attempts, no significant improvement combined with capacity below 60% of rated capacity indicates possible replacement. While programming any of the five modes, holding ENTER for two seconds copies one slot’s settings to the others. After prior operation, the charger automatically resumes its remembered setting if power remains uninterrupted.
