Power supply is a 900amp 12v jump starter. I have a multimeter and will check it tomorrow.
All pins and connections appear fine nothing bent, dirty or corroded.
I will have to check or post another thread to see if anyone has a SS2K hand controller in Perth (a very good idea).
The new battery was correct and I was aware of overheating with soldering/desoldering and made sure the new battery came with tabs as it was available both with and without. I will open it up again and inspect it. I have retained the old battery and will compare them just in case.

Thanks again

David
