New car - dead battery?

I blogged about needing to replace the battery in the Jeep before going to Mexico (https://journeyinamazinggrace.blogspot.com/2025/11/more-battery-news.html).

I also blogged about our new car purchase (https://journeyinamazinggrace.blogspot.com/2025/12/weve-done-thing.html). 

I left Carl "unsupervised" while I was volunteering in the Activities Office on Tuesday... and he was in the new CR-V trying out different things with the car in accessory mode in our driveway. He started getting odd messages on the on-board screen in the car, and then it died. He realized that the starting battery must have run out of juice. As I was driving the golf cart back home after my volunteer activity, he met me walking toward Gracie to get the jump box and battery charger. He told me that he had killed the new car, and I thought he was kidding! Nope, he had killed the new car!

He took the golf cart back to Gracie and got the jump box and battery charger... 

He got the battery charger hooked up to the battery in the new CR-V.

Now, you may be thinking (as we were) -- it is a brand new car! How could the battery die with just 1-1.5 hours of powering electronic stuff in the car? 

We figured, however, that the car has not been driven much (it only had 31 miles on it when we bought it), and the alternator would only charge the battery if the gasoline engine was on. If he had turned the engine to "on", the electric motor would have only run a little while, but when the system determined that the start battery needed charging, it would have started the gasoline engine (or that's what we hope!). Since it was in accessory mode, the use of the electronics were enough to discharge the battery. We could have called Honda Care and they would have dealt with it, but since Carl had the equipment to re-charge the battery, we did it ourselves.

We have a plan for a longer road trip that will require the gasoline engine more so hopefully all will go as designed and we'll have no more unexpected behavior!
