A question on a 2007 Acura MDX with Acura branded battery. No idea if original.
The other night I started talking on the cell phone prior to starting it. I had the key in on position though. The vehicle is overloaded with electronics including navigation, bluetooth, two heating systems, head lights on automatically and wife left passenger seat heater on. Interior lights were all on (probably 9).
So after 15 mins I see a Air Bag warning for Low Power and everything starts flickering. So of course it does not start and requires a jump. It restarts fine and only issue was radio needed code to work again. It happened once this summer too with wife while she waited for someone for 20 mins. It started but reset all sorts of things.
I had the battery tested this past summer and was fine by competent mechanic. Is doing what I did unreasonable or battery flaking out?
