The Nitecore D2 charger is a universal smart charger that is compatible with the majority of cylindrical rechargeable batteries. The D2 automatically detects Li-ion, Ni-MH, Ni-Cd, and LiFePO4 batteries. The clear display screen provides charging progress, voltage information and the remaining time to complete charging and will automatically sense when charging is complete and go into sleep mode. 

The Nitecore D2 charger is the most advanced automatic digital charger on the market. Toss in some batteries and pull 'em out when they're fully charged!
