more electronics than electrics - battery and charging question

psychicwarrior
this pic --> https://drive.google.com/file/d/1gunP4gFyIucj0ITstccf2D2szu3cw17O/view


is of parts of a radio that has a compartment for a rechargeable battery. 


From the pic and the pin voltages I measured (measurements not accurate I'm sure), is it possible to 'suggest' how the battery was wired/connected to the pins ?


It is a Genus Type-R DAB radio from yesteryear and the manufacturer no longer exists and getting hold of tech diagrams or info from other sources has proved fruitless.  The base plate states 7.2V battery pack.


Some companies have suggested they can put together a battery unit for me to fit, but they need to know how the leads need to be connected from the battery to the internal charging connector (4 pins)  and I cannot get from anywhere a manual, or a picture etc.


If it is possible to work out from the above picture etc, please let me know though I doubt without the manufacturer info it is likely possible (from what I've been told so far).  Additionally, I tried contacting one person who I found selling the radio, but they too had no battery to send a pic of.

    @sparking - :-)    you were only saying what a few have already...you are not alone :-)


    my reason to raise it was to see if any one could decipher the circuit board, pins, voltages etc to  rustle up a guess on how a battery for that radio would be wired.    as i say, if that could be sorted a number of battery 'makers' out there have said no problem to putting one together !


    easier said than done...well for me at least.    i will plod on until the shoe leather is worn out and i have no more desire....but  it is interesting in some way.  I will try the @mapj and @zoom date collecting and see where it leads.
