Battery for NEC MP5B2D2 analogue vintage classic mobile phone

The NEC MP5B2D2 was an analogue phone that was liked by many because of its relatively small size - it would be fitted into a pocket and it was not a transportable phone which required an additional large battery, etc. It was actually full portable.

Although, but today's standards this analogue phone was still quite large, it was nowhere near as large as some of the other phones of the day.

However with the launch of the second generation phones for networks including GSM, cdmaOne, TDMA, etc, it did not remain relevant for as long as might have been initially anticipated.

MP5B2D2 was designed to operate on E-TACS, the extended TACS - Total Access Communications System. The system used frequencies around 900 MHz and the extended version of TACS added additional channels giving a total of 600 channels to provide the additional capacity needed as the demand was growing.

E-TACS added additional channels but the system had a 25 kHz channel spacing, 9.5 kHz peak frequency deviation for the FM signal used.

The NEC MP5B2D2 offered the advantages of a much smaler size when compared to other mobile phones of the day. The version shown was for the E-TACS or extended TACS system but other similar versions were available for other analogue systems used in different countries.
