* Note! In BL-5C battery IF the BTEMP signal doesn’t exists. Temperature measurement is done on system board
with NTC resistor.
Figure 150 BL-5C battery connection order
Battery
• Type: BL-5C
• Technology: Li-Ion, 4.2 V charging, 3.1 V cut-off
• Capacity: 900 mAh.
The BSI resistor is placed on the main PWB as the telephone supports only one battery capacity. Further a BSI
connection is added to the Flash interface. The battery temperature is measured by a NTC resistor placed on
the main PWB, opposite to the Battery. Battery pack has an impedance of 130 - 150 mΩ (0 – 45 °C).
