Last weekend my wife reported that the battery was dead in our 2000 Honda Accord V6.
I charged battery overnight; started fine after I put it back in. Looked for drains with a multimeter; after a few minutes, current went down to 12 mA, which AFAICT means there's no way it could empty the battery. (Car had been parked at most a couple days, and it's pretty warm here.)
After getting some reasonable replies in a different thread here, I took it to Advance Auto Parts and had it tested for free. Everything checked out fine.
Anyone have any ideas? I know that electrical issues can be notoriously hard to diagnose. Is it possible there's something about the alternator or the rest of the car's electrical system that the test at Advance would have missed? (The test is broken down into a few parts (battery, starter, charging system), all reporting normal.)
Also, if there was something seriously wrong with the alternator or battery, I assume I'd be getting dead batteries more frequently. We had a dead battery quite a while back, probably due to cab light being left on. After that, last spring the alternator went bad. Had that replaced. A couple weeks after that, left it at the airport for about
5 days; dead when we got back. Had it jumped. It's been fine until last weekend. THat's a pretty big gap (early May to mid August).TIA
