    My 2008 has new batteries. One night it died because a door wasn't fully closed. Charged. Running fine but then after a few days, it was completely dead. What could be draining both of my batteries? It had gasoline. I don't know what is going on. There was no warning light.

    This is your 12v battery, not your hybrid battery... Due to lack of vehicle use, quite common during covid, there's lots of 12v batteries that don't get enough drive time to recharge. Buy yourself a high quality 12v charger and charge it up. Don't waste your time with cheap trickle chargers, you need more amps to get it fully charged.
