******** MTH800 without battery on charger
i would like to use an MTH800 without any battery while it is connected to the charger, since the radio won't turn on without any battery
even when i connect 4V to the battery connector of the radio, i get an error message, that a wrong battery is inserted
does anyone have an idea, how this is possible?

Hi,
You have to use or build a battery eliminator using old or dead battery, there is one-wire device used to identify accessory type.

The battery has an internal resistance which is detected by the radio as being "valid".

@-bup- i already thought about sniffing the datastream and programming a microcontroller to output the same data, when it is connected to the battery pins in the radio
@nokiaman2002 if it is only a resistor, it would be easy to be done
