At various dealers are available battery clips for contacting 9-V block batteries.
    These batteries also carry the designations 6LR61, AM-6, 6F22 or PP3.
    They have contacts that looks like snap buttons with different sizes.
    
 
    
These batteries have only a small capacity.
    Therefore, the connection wires of the clips are only designed for a small current and are quite thin.
    For electric consumers taking in a higher current, they seem unsuitable.
    The thin wires produce a relatively high voltage drop.
    However, I wanted to use a battery holder that only has contacts like on a battery clip.
    Since the intended electric consumer, here a transceiver, draws a lot of current, another solution had to come from.
    
 
    
    
    When one open one of the available clips, two contacts appear on a thin supporter.
    First remove the thin wires from the contacts.
    Then you solder new thicker wires on it.
    At the end, you isolate the supporter with the soldered wires.
    I used self-amalgamating insulation tape for this.
    It is enough to cover the soldering points and fix the wires.
