This is Simple! Insert...Detect...Charge!
The Nitecore D4 is a universal, intelligent charger that is compatible with most types of cylindrical rechargeable batteries.
It is able to automatically identify Li-ion, Ni-MH and Ni-Cd rechargeable batteries** and selects the appropriate voltage and charge mode. Please Note: LiFePo4 requires MANUAL selection.
An integrated digital LCD screen clearly displays charging progress, voltage, current and time. This Nitecore charger is the most advanced fully-automatic digital charger on the market.
Capable of charging 4 batteries at once, each of the four charging ports is independently controlled by its own microcomputer. And it STOPS charging when complete -- No Overcharging!
