In part.. they don't draw 'MUCH'. Simply continuously energizing those lines, resistance in connections, line loss in itself and resistance in fusing (heat) hour upon hour... you're still slowly chipping away with an increased parasitic draw even when in disconnect.
I know it's "kosher" to, in general, quote "typical" parasitics in the 1-2 amp range... but I HAVE seen much higher and noticed a few folks taking it for granted without doing a real world audit.
Getting to the heart of phantom draws is quite difficult. Just my own experience.. in complete and utter shut down I still can't seem to break under .2. THAT took some serious tweaking and, more than naught, was redoing clamps and shrink wraps from professional shops just to eek out almost worthless percentages.
Granted.. some of that is coming off normal offgassing. But with my AGM's averaging around 1.78% every 37 days in 'nominal' temperatures I would hazard to guess that most folks with quality wet cells still can't begin to touch that.
If I had "standby" connection in my lines, that number would at least quadruple I would think. And that's, "disconnected".
I'm not trying to bash anyone.. it's just the nature of the beast and not very practical to look through rose colored glasses and assume even a 1 amp parasitic draw is realistic.
It's nice to play with though.
