Yeah, you only changed one of your batteries though. Because they are connected in parallel, the maximum output of the pair is the same as the weakest battery. So on a cold day your brand new battery should have 13volts, but your other old knackered one is only putting out for instance 8volts. So total voltage flowing to your starter will be the same 8volts - so the van wont start. I did tell you to change both batteries together...
Was it tested by the same person who said both batteries were "spot on" when one of them was well and truly rogered? How was it tested?
Disconnect your old battery and remove it from the engine bay, now connect your new one in by itself, don't worry about the extra connectors - just make sure they're not shorting out on anything. Now try starting it - my suspicions are that it will start fine, in which case you need another new battery.
