    The difference in measurement may be a conflict with the meter's battery. I would dismiss that reading reversing the leads.

    My 07 had a similar situation.... I went through about 13 batteries in about a 9 month period. All stock, "new" wrecked in the lot, would die pretty much anywhere... like you stated, walked to the restroom and back and it was dead... I took it in to the stealership about 10 times... got all "new" batteries but they kept dying. It spent 3 weeks in the stealership's parking lot and they supposedly brought some engineers from Texas and Japan with some overnight parts from Japan it would decimate all, LOL joking about the parts, but not the engineers... it appeared that heat was killing the batteries, as well as the Optimas they don't like being stored in either extremes... the last 3 batteries I killed were 2 Optima Red Tops and found out that they limit 2 warranty swaps before they decline swaps and charge you for new ones. Just like the draw started it stopped.... It recently sorta returned, just killed 2 yellow tops within the last 18 months, so I would suggest like above, pull fuses, check your alternator it may be intermittent, possibly may not be charging the battery...
