I have a 2007 Odyssey and all has been working good for the most part. However, I have a question regarding its battery/electrical system.
Several times over the last few years, I have apparently been in circumstances that have accidentally drained the vehicle's main battery. In all cases, they involved either leaving the DVD player running or external XM radio running (& plugged in via 12V port) with the engine turned off. A simple jump from one of our other vehicles has then gotten it back to normal and all continued to work good. In all of these cases though, it involved the device (XM radio and/or OEM DVD player) running for only about 5-10mins before the car becomes disabled and needs a jump.
The latest occurrence happened this morning when the wife put our son in the car in the garage and was letting him briefly watch a DVD for about 10mins with the engine off while she was gathering other things inside the house. When she came out & tried to fully start the car, it would not turn over. She will be able to use another vehicle until I can get home and do the jump, but is this 10min time frame normal before the battery needs to be jumped?
I have an old '94 Nissan truck and I have left the radio on for 45-60mins before and am easily able to start the vehicle without any issues. Is this maybe some kind of Honda safety issue or something? Like I said, once we jump it, all works great and continues to do so for months at time before this accident may happen again.
Just curious about this situation and while we TRY not to let this happen too often, I'm sure it may again.
