When we were still going through the Covid lockdown, our Passport, which is pretty much just our road car, would often sit for 6-8 weeks at a time without getting started and never once even turned over slowly. I've never once since we bought it in Sept. of '21 had it on a Battery Tender. I do keep my Tiger Explorer on a Tender and my Cub Cadet Z Force S has a Tender hooked up to it from late November through March. Our Passport is the 4th 3.5L Honda since '06 and I've never had a charger or Battery Tender on any of them in over 300,000 miles. Zero issues.If that is normal for you vehicle after 24 hours, then you have a problem. I have let my 2020 Touring sit for over 15 days, no tender and it starts right up. SOC was down slightly but it was back to a full SOC with the drive I had to take.
