I noticed the first oil change a month before the dead battery, they tested the battery and it shows “battery good” with voltage 12.54, measured 612 CCA, rated 410 CCA, temp 111°F. Does that mean anything, and if those results are expected from a brand new battery, how likely can a battery just go bad?
BillRussell - the charger is 2 (might be rounded) amps. There’s a port for 5 amps, but nothing is plugged into that one - that’s for ‘fast charging’ whatever, not the iPhone though.
shadowfax - I meant that nothing was manually turned on, and if it could be manually turned off, then it was. I realize a car is not a battery pack; the manual does state a couple times about the ports and accessory power socket being used to charge devices, so this car (as I’m sure with others) was designed with this in mind. I’ll have to check that radar emitter thing, good idea! As to a slow head unit, if I click the Audio button to display the currently playing station, it’ll take several seconds. If I click the settings button, it’ll take a few more seconds. Sometimes it’ll take maybe up to 15 seconds for a screen to come up, but usually it’s a few seconds - to me that feels sluggish, even slow compared to trying a Samsung Galaxy 6 on it (3 or 4 year old phone). Ha, sorry about that natural sounds thing - you know when you turn on a TV, you’ll hear a little pop or electrical crackle? Or when you flip some light switches, usually older ones, you’ll hear a little pop of electricity starting to flow? That’s what I’m referring to, those seemingly normal electrical sounds when something turns on or off, I hear that often with ACC and maybe it’s just be now noticing it, but it seems louder than it should, chalk on a chalkboard after a while.
jtsanders - I’ve heard the same about the Honda and the car putting on the brakes, but with no human explanation a couple times now, and the harsh deceleration it did, yeah i think it needs a lot of work.
thegreendrag0n - thanks for the test idea. Maybe i can do that at Auto Zone this weekend since they have the equipment and it’s free. Any other test ideas? as for questions: #1 it’s about 20 miles and about 1 hour, car sat in the parking lot for about 7 hours afterwards when it was then used to charge the phone. #2 the car was purchased with minimal miles about March of this year. The dealer kept it for several days afterwards to do the interior lighting. Do you think this is still possible, even a few months after they did that install and a month before the incident, their battery test shows “battery good”.
whitey- good point. i thought about calling places, honda or dealerships, and ask point blank some of these questions, but i’m not sure i’d fully trust whatever answers i get, they have their business interests in mind.
