7.1 Specification
The C25 battery is a NiMH type with a voltage of
3.6Volts and a capacity of 700 mAh.
Suppliers are Varta and Maxell. You can easily
recognize the manufacturer by the colour of the battery
cells: Varta’s cells are of a green colour, Maxell’s ones
are bluish.
The connections BATT+ and GND are used to supply
the phone with power. The connector BATT_TEMP can
be used by the mobile to measure the temperature of
the battery cells.
Insertion of battery:
To insert the battery the right way round, on the
housing inside the battery compartment of C25 and on
the battery there are two arrows, which have to mach
each other. If the battery would be inserted any other
way round, the battery cover probably can be closed,
but the phone of course will not be operational.
