Charging Li batteries at less than 4.2 V/cell is possible but also not recommended. While other battery chemistries do not charge at low voltages, Li batteries will charge but will not reach full charge. An advantage of charging at lower voltages is that cycle life goes up substantially but with much lower capacity.
The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and charger circuits for use with Nickel-Cadmium (Ni-Cd), Nickel Metal-Hydride (Ni-MH), and Lithium-Ion (Li-Ion) batteries.
The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.
