Did the battery end up taking a charge after running the car for awhile?

Hi Brad, it did although I had to jump it again after I stopped 15 minutes later to have a look at a random used car. This was filmed last weekend and I've been driving around since and it's been fine. Ideally however, I'd like to take it onto the motorway for an extended drive to get the battery back to optimal, and next time I store it I'll disconnect the battery.
