Good call on dumping the Paralax for the PDI, I did that 7 years ago and never looked back.
The length of time the PDI stays in "regular mode (fast Blink is directly proportional to the voltage of your batteries. Mine has stayed in fast blink for 24-48 hours when back from a trip.
I got this from PDI a while back, hope it helps you
Shore or Generator power on:
Storage mode Blinks 6-8 seconds apart
Regular mode Blinks from 1-4 times per second
Boost mode Solid Lite
Power off: Battery Connected
Fast blink is above 12.77 many times a second
Slow blink 11.95 - 12.7 1 -2 times per second
The light will go solid around 11.9 volts

I think the guy may have been high or the blinks on battery have been reversed since I bought it as mine goes from solid to fast blink to slow blink as the batteries discharge.
