    I have an old Panasonic mobile. The battery is damaged and I want to
    use my mobile without the battery. When I remove the battery the phone
    doesn't work anymore. The battery has four contacts a + and - and R
    and S. I think the last two are for a built-in thermistor to control
    the temperature of the battery. I measured the resistance between R
    and S: 11.5 kilo ohm. When I short with a resistor the mobile won't
    work either.
    What am I doing wrong
