Hi,
You pretty much need a PRAM battery. You can't even leave it plugged in.
Why, you may ask?
Well...
Because of the way the power supply is designed (no soft power), flipping the switch cuts off ALL power from the logic board, and therefore the PRAM. In other words, there's no provision for a trickle "clock" voltage.
The only way to prevent the PRAM from being reset without a battery is to pretty much leave the computer on 24/7/365 (although, depending on current circumstances, that isn't very feasible).
The same is true of the Plus (I shipped it without a battery). Unless you keep it on forever, it'll never retain it's PRAM without a battery.
I hope this helps!
