Product overview
The FLYPOWER 1.2V AA2000mAh low self discharge Ni-MH battery (RTU type) combines AA format with nickel-metal hydride chemistry. It has a nominal capacity of 2000 mAh under standard charge/discharge conditions and a nominal voltage of 1.2V under open-circuit conditions. Caliper-measured dimensions are 14.0+0.5 mm in diameter × 50.0±0.5 mm in height, with an approximate weight of 28.5 g. Maximum continuous discharge current is 4000 mA (2.0C) at an ambient temperature of −10–50℃.
Standard charging uses 200 mA (0.1C) at an ambient temperature of 0–45℃ and takes approximately 15 hours. Fast charging uses 1000 mA (0.5C) for approximately 2.4 hours at an ambient temperature of 10–45℃, with −ΔV=0–5 mV per cell, a timer cutoff at 105% input capacity, a temperature cutoff of 45–50℃ and dT/dt=0.8–1℃/min. Discharge cutoff voltage is 1.0 V below 1.0C discharge and 0.8 V at 1.0C–3.0C discharge.
At 40–60% charge, storage temperature ranges are −20–50℃ for less than 30 days, −20–40℃ for less than 90 days and −20–30℃ for less than 360 days. Storage relative humidity is 65±20%.
