I finally got around to checking this with some of the new style Bosch solid 
state voltage regulators that I have here in stock. I found one to draw 0.54 
mA and a second one to draw 0.57 mA. That's with a battery that's sitting 
with ~12.6 V on it.

That appears to be by design, and it's not much. It's probably less than the 
self discharge rate of the battery. At that rate, it would take more than a year 
to drain 5 AHr out of the battery.

I can't explain why the current I measure is only ~10% of what William 
measures.
