The unit might not go into storage mode for a couple of days with no use. If you turn on a light, or anyhting electrical, the process can start over again. It sounds like you have a lot of electrical devices pulling power when you think they are off. The CO alarm, radio and TV are all pulling power. There may be other devices you are not aware of, the antenna power supply comes to mind. I would not expect you will ever see storage mode in that situation. The charger probably went into boost mode to replenish the power that those devices are using. Sounds like the converter is working properly. You might want to confirm the health of your batteries. Going into boost mode usually means the converter is unable to keep up with the current draw and that can be an indication of failing batteries. If you are going to have electrical hookups in baja, which you would need for the converter, I would not be overly concerned.
