My 2019 CR-V battery died at the airport after sitting there for 4 days. It was Chicago in winter but the temps weren't too dramatic. The CR-V had less than 1000 miles on it. Got a jump and drove 40 minutes to drop it off at the dealer for analysis. Couldn't find anything. Provided me with two graphs. one was 40% charge of battery upon arrival and the other showed 100% after fully charging the battery. They told me they checked the alternator and it was ok. So battery ok and alternator ok. So everything pointed to operator error. Although there's a first time for everything, I don't believe I left anything on when I exited the car. Like making sure you shut the oven or the iron off when you leave the house for a long trip.....you are extra cautious and make sure everything is off.
The dealer had no explanation other than to say the new vehicles have a lot of electronics on them...and left me with basically..."if it happens again, let us know."
I see that others had similar issues and another forum member also mentioned a software fix.
Looking for opinions on the following:
1) has anyone received confirmation that Honda has recognized this as a problem?
2) I read not to use the ECON button as the battery doesn't charge all that well when used in cold weather.
3) To prevent from getting stuck again I would like to buy a portable battery car jumper. Does anyone know which is a good one to buy for this car or will any of them work?
4) The battery looks tiny to me, doesn't quite fill the holder and is 410 CCA which seems quite low for Chicago winters. Did Honda put too small a battery in this car?
5) After a 40 minute mostiy highway drive after the jump start, the battery was only 40% charged. Does that sound normal only 40%? Once it was jump started,
pretty much all of the cabin electronics were shut down due to the dead battery so its not like there was much battery draw that I was creating.....
Anyway, if anyone has any wisdom to share...would be much appreciated!
