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

Main Features:
? Capable of charging 4 batteries simultaneously, each of the 4 battery slots monitors and charges independently
? Compatible with and identifies Li-ion, Ni-MH and Ni-Cd rechargeable batteries, LiFePO4 batteries require manual selection

? Integrated LCD panel clearly displays charging parameters and progress
? Intelligent circuitry detects the battery type and status before entering automatic charge mode (CC, CV, dV/dt)
? 2 conveniently located side buttons allow easy selection of specific battery types and charging parameters
? Automatically stops charging when the battery is full
? Features reverse polarity protection / over-charge protection / temperature monitoring 
? Thoughtful overnight charging function, turning off the LCD backlight to eliminate disturbance at night
? Made of flame resistant ABS, which is designed for optimal heat dissipation
? Operates on either AC 100 - 240V around home or office or DC 12V when used in vehicles
? Certified by RoHS, CE, FCC and CEC
