Please upload good clear pictures so we can see what we are dealing with.
What are the original battery?
When did this issue occur?
Was it working OK with battery before?

It looks like the PR-633496 has 3 leads, I suspect that could be the problem, That is the temperature sense lead and may be shutting down the circuit
