7 Battery

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.
