I have to say I don't have a high opinion of (at least one of) the two mechanics you've consulted already....
To clarify - if there is an immobiliser fault, the engine will spin over on the starter motor for as long as there is charge in the battery - but it won't start. In this case the yellow immobiliser (key) light will be on.
If the starter is faulty, the engine won't spin over, or at best very slowly - of course a flat battery will have this effect too. If the battery is flat you may get lots of other fault warnings too, but it is unusual for the immobiliser light to be on.
As said the positive battery lead is bolted to the battery terminal by a 10mm bolt on the clamp - there may also be two screws holding the terminal block to the battery case. When refitting a charged battery, ensure both battery terminals are firmly clamped, and also check that the earth lead connecting the bodyshell to the gearbox is a good contact.
