Nitecore D2 Universal Charger


The Nitecore D2 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The D2 automatically detects Li-ion, Ni-MH and Ni-Cd 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 D2's two 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.

The Nitecore D2: Advanced fully-automatic digital charger. It's as simple as insert, detect and charge.
