OK, let's push this by process of elimiantion.Allow me to share all these frustrations/issues with you as I researched this battery issue.How old is your Odyssey and I am assuming it is the 925 or 680? If the latter then this inquiry would be even more important.Per Odyssey, the 3 mile drive even with 40 minutes traffic is not sufficient to charge the battery at full capacity if it has not been maintained or is running at say 75% capacity. It will crank but the low voltage will send the cell codes and this is particularly the case with 680 and 925 in cold weathers with a sensitive ACM.That is why they recommend the 1400 for the NSX, or the 1200 with a battery tender. For NA vehicles, the 925 might work but they still recommend a battery tender. And the NSX is quite finicky with voltage issues. The alternator is not sufficient; it will do its job up to 13.5v (+/-) but Odyssey likes 14.5+Try really deep cycling your Odyssey and see if that resolves it. It is a cheap option and might work. Then, use a battery tender with higher voltage.
