Nitecore and Samsung
•Samsung INR18650-25R 2500mAh •Max. continuous discharge current: 20A •Safe pulse discharge ratings: 95A < 0.5 sec, 65A < 1 sec, 40A < 5 sec, 30A < 6 sec •Nominal capacity: 2500 mAh •Nominal voltage: 3.6 V •Discharge end voltage: 2.5 V •Charging voltage: 4.20 +/- 0.05 V •Standard charging current: 1.25 A •Length: 65.85 mm •Diameter: 18.33 mm •Weight: 45.0 g Nitecore D2 Capable of charging 2 batteries simultaneously and each of the two battery slots monitors and charges independently Compatible with and identifies Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340 (RCR123), 14500, 10440), Ni-MH and Ni-Cd (AA, AAA, AAAA, C) and LiFePO4 batteries The Nitecore D4 is an universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The D4 automatically detects Li-ion, Ni-MH and NiCd batteries, and through manual selection is also capable of charging LiFePO4 batteries. Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the D4's four microcomputer-controlled charging slots then monitors and charges the battery independently. Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current and time while an intelligent automatic power-off function terminates current when charging is complete.
