The Nitecore D2 is a universal smart charger compatible with almost all cylindrical rechargeable batteries.This eliminates the need to own several chargers.
The D2 automatically detects the battery type and an intelligent charging circuitry selects the optimal charging mode for each of the two microcomputer-controlled charging slots. This then monitors and charges the batteries 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.
