It is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. It is compatible with not only Ni-MH, Ni-Cd, 3.7V/3.8V Li-ion batteries but also LiFePO4 batteries, in which it automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging 3.8V Li-ion batteries and LiFePO4 batteries. Intelligent charging circuitry selects the optimal charging mode 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. And it supports automatic power-off function when charging is complete.
Capable of charging 4 batteries simultaneously.
Each of the four battery slots monitors and charges independently.
Integrated LCD panel clearly displays battery type, and charging parameters and progress.
Charge Ni-MH, Ni-Cd, 3.7V/3.8V Li-ion batteries or LiFePO4 batteries in any combination.
Compatible with and identifies Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440), Ni-MH and Ni-Cd (A, AA, AAA, AAAA, C, SC) rechargeable batteries.
Compatible with LiFePO4 batteries.
Intelligently detects the battery type and status before automatically selecting charging mode, except for 3.8V Li-ion batteries and LiFePO4 batteries which require manual selection (with the help of yellow side buttons).
Two conveniently located side buttons for 3.8V Li-ion batteries and LiFePO4 batteries. SLOT: to lock the corresponding LCD panel; MODE: to choose battery type.
Supports automatic power-off function when charging is complete.
Features over-charge prevention to protect batteries.
Features diagnosis and protection for reversed battery connection or unexpected short-circuit.
Recondition Li-ion batteries with protection board, which are instantaneous short circuit.
Recondition battery if the battery voltage over 0.2V.
Auto detection of non-rechargeable battery or defective battery.
Designed for optimal heat dissipation.
