I have a 2016 Honda Accord V6 with only 22k miles. I am retired and bought this as my retirement car, so it does not get driven much as you can see. Oh yeah, it's in Florida. So I go to start it last week and it won't start, dead battery. Well known issue for batteries (it is the original battery) in Florida. Battery won't accept charge, reads only 10.5 volts. Replaced battery. BUT, there is no voltmeter in this car, but I do have a plug in the cigarette lighter voltmeter. So, even though I do not have a battery light lite on the dashboard (and never did), just to make sure the charging system is OK, I plug it in. Mind you, I have never plugged it in before so I don't know what normal is on this car. Well, it reads 14.4 at idle. But as soon as you put it in gear it drops to 12.4??? and stays there as long as you're at a stop (~800 rpm in gear). When you start driving it will eventually come back up to 14.4. At no time do I get a battery light on the dashboard. I'm concerned something else is wrong. Of course, if I hadn't plugged the voltmeter in I would not think anything was wrong and would just keep driving it. Any ideas? Could this be normal? It is not on my other cars. In or out of gear voltage runs between 13.4 and 14.4 on my other cars. PS - I have attached a real voltmeter to the battery to verify what I am seeing at the cigarette lighter. It is .2 volts higher at the battery, that's all, which means it is actually dropping to 12.6 volts at the battery. New Battery reads 12.9 with car off.
