6.8 Features of Lithium-Ion (Li-Ion) batteries
Lithium-Ion batteries have several features that make them more suitable for use in portable handphones than
other materials used, such as Nickel Hydride.
Lithium-Ion batteries are better for the environment as they do not contain any regulated materials, such as
mercury, cadmium, lead etc.
You may be mistakenly lead to believe by the name that Lithium-Ion batteries contain Lithium metal. In fact they
contain no Lithium metal and are therefore safe to carry by air transport.
A great advantage of Lithium-Ion batteries is their ability to be recharged for between 300 and 500 times. Lithium-
Ion batteries exhibit no "memory effect", as is observed with repetitive shallow discharge and charging of Ni-Cad
batteries

6.8.2 Charging Li-Ion batteries
The following points should be born in mind for the charging of Li-Ion batteries:
Li-Ion batteries require a constant charge voltage of 8.4V for all G600 battery chargers (dual charger EB-CR600
and handsfree charger).
Charging will be at 1.5CmA (where C is the nominal capacity of the battery). The charging current will naturally
decrease to OA while the battery voltage remains constant.
