Help with Battery Issue?

I received these messages after leaving my car in “accessory mode” this afternoon. I ended up needing to jump-start it to get it running again. Any idea what might have caused this?


Sounds like a low battery issue.

Battery might be dead. It’s less likely that the alternator has failed already.

Your battery is probably dead. Also, clean up your dashboard a bit.

How old is the battery? Hondas don’t like weak or old batteries.

Take the battery in for a free test. If it’s okay, then maybe the alternator isn’t charging it enough. If the battery needs replacing, consider getting an AGM type battery.

Exactly what I was thinking. Either the battery can’t hold a charge anymore or the alternator isn’t doing its job. Hopefully, it’s just the battery since replacing the alternator can be a pain.

Most likely the battery is weak, possibly drained from accessory mode usage.

What’s the year, model, and mileage? As a general tip, it’s good to replace the battery every 3 years.

Update: Both the battery and alternator are fine.

Are there any engine codes showing?

If you’re going to use the radio or power outlets, it’s best to keep the car running. Leaving it in accessory mode too long can drain the battery.

I’ve had electrical issues with my 2020 Odyssey since the beginning. Trickle charging overnight for several days helped extend the battery life.

Looks like your battery got drained.
