Don't double post.

Kinda obvious based on your description. Replace your 12V.

Replace 12v before restarting or it will drain your 300v hybrid battery.

I don't know if the dealer can trickle charge the 300v battery. But a diagnosis code would help.

This a part that I do not understand. If you do leave on the radio/lights etc. does it drain JUST the 12V battery under the hood or does it draw power from the Hybrid battery under the seat also?
