Battery powered (not 12V) propane detector / alarm.

[JW2]

I need to replace my propane detector / alarm. The one I currently have runs on 12V. I tried to find one that has its own self contained battery, but could not find one. Does anyone know of / or if there is one that runs on its own battery power (i.e. is not connected to the camper 12 volt system)?

Thanks in advance for your help with this.

I think they take too much current to be battery operated. I just bought the new Atwood unit and it says it pulls .045A.

When mine went bad I got one at Camping World.

I've never seen one. Always powered by either 120 AC or 12 DC from main house battery.
