My accessory battery recently went dead after not driving the leaf for a couple weeks. It is a 2012, so it is probably time for a new battery. But it got me wondering:
WHAT DRAWS CURRENT WHILE THE CAR IS COMPLETELY OFF?
HOW MUCH CURRENT SHOULD I EXPECT TO BE DRAWN FROM THE ACCESSORY BATTERY WHILE IT IS OFF AND PARKED?
I measured it at about 0.5A which seems like WAY too much to me to run the various computer stuff, key sensors, alarm system, etc. in the background. What do you think? 500 mA is a fairly big load, about 7 Watts. No cabin lights are on, nothing on on the dash indicators. Do you think there is something wrong, or is a continual 500mA draw from the accessory (12V) battery perfectly normal? I read here how some of you routinely hook up battery top-up chargers to their 12V battery to overcome the Leaf's poor ACC charging routines, or an aging ACC battery's small capacity. But is this a bandaid for neglecting to fix something that is wrongly drawing the ACC battery down when the Leaf is completely off?

Thanks,
