Charging Operation

Battery

The 1265 uses a Lithium-Ion cell battery with a capacity of 860 mAh. QSC6010
reads the resistor inside the battery pack on the BSI line to identify the battery size.
Different charging algorithm will be used for different battery sizes. The resistors are
connected to the BSI pin inside the battery connector.

Charging Circuitry

The PM charge control is dependent on the charger type and the battery size.
External components are needed for electromagnetic compatibility (EMC), and
transient protection of the input to the baseband module. The charger's DC input is
through the dc-jack connector. This mobile terminal supports AC-3/AC-4 & DC-4
chargers.
