I just ran into a similar issue that might bite someone else - it brought me to this SO question after turning on debug and getting that 'batch acquisition of 0 triggers' message.
I had a job that was every 2 hours like this:

"0 0 0/2 * * ?"

And I wanted to make it more often, so every 2 minutes like this:

"0 0/2 0 * ?"

I even tried https://cronexpressiondescriptor.azurewebsites.net/ which gave me a big clue I should have read more carefully: Every 2 hours, on day 0 of the month which eventually made me realize what I really meant was:

"0 0/2 * * ?"

So the lesson was, when 'shifting left' your cron, back-fill with *, not 0.

Hope that helps someone else.
