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.

    @zoom @mapj - thank you, i will have a go at the suggestions. i may be a while coming back though so please bear with me.


    @zoom - yes +ve centre pin  (and I have already written to that seller to see if they had anything...same boat as me)


    @sparkingchip - what are you trying to say with your contributions ;-)    "dont bother"



    As I pointed out, I;ve tried many many places and I know its all a long shot.  I picked up the radio as a freebie and thought I'd venture to see what could be done.  A company has said they would package up something to fit the battery bay, but would need to know the pin config and how the battery is to be wired etc...as I said.  @mapj - I think you are on the same lines as another electronics person mentioned to me...it could be tricky due to the possible configs.


    Regards


    PS: i use linux and this editor thing to use for posting is quite frutrating...for some reason the cursor flicks about and makes edits in odd places.   dont have this problem with other 'rich text' editors i have come across.  Some of them have the ability to turn off 'rich text' functions and just use a 'normal' text editor...hint..IET  :-)
