The Nitecore D4 is a 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 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 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. The Nitecore D4: The world\'s most advanced fully-automatic digital charger. It\'s as simple as insert， detect and charge.
