The Intellicharge i4 is a universal, automatic smart-charger compatible with almost all types of rechargeable batteries thus eliminating the need to own several chargers. The i4 is able to automatically identify Li-ion, Ni-MH and Ni-Cd rechargeable batteries and apply an appropriate charging mode (Constant Charge Current (CC), Constant Charge Voltage (CV) and Trickle Charge). Each of the i4 has four microcomputer-controlled charging slots which are capable of monitoring and charging the same type of batteries. Additionally, yellow and blue power/charging status indicator lights could visibly indicate battery status and charging process.
