Review on MTI 20-441-WT: Reliable 12V White Surface Mount LP Gas Detector by Tristan Graham

Easy to install in my RV with existing 12V wiring under the bed. This device seems to be draining my batteries. I have well maintained and only a few years old 450Ah batteries powered by a 200 watt solar panel and PWM charge controller. Every morning my batteries go down to about 70% and the only thing plugged into it is an LPG detector which is hardwired and works all the time. I suppose you could hook up a switch and just turn it on when camping, but I wanted something that just always worked and was reliable. I'm not sure if any device is causing this type of leak on a battery pack or I have a leak somewhere else.
