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.

    My old Roberts radio is very Eco/green. It runs for ages on a 9 VOLT PP9 battery


    I can't find the source now, but somewhere I read that the energy taken to make a battery is 50 times more than the battery will give out.

    But my battery lasts 200 times longer than those used with DAB radios.  Also the old "analogue" radios work in synchronisation if several are used at the same time around the house, unlike digital DAB radios that all process the signals at different rates and "clash" due to being out of synch. with each other.
