Propane Alarm Recommendation

[Mattkcc]

I got my Plat Cat up and running and remembered I need a propane alarm. Got on Amazon and ordered a Safe T Alert Propane Alarm. I got it due to it's smaller size. I didn't see any of the 12volt units give the power consumption for there alarm, got my alarm today and when I took it out of the package the wires caught my attention 14ga.. Went through the paper work and this alarm uses 75mA, found a review online about this alarm and the guy has 450mA in batteries and the alarm pretty much drained his batteries over night. 

Anyone use a propane alarm that won't drain my battery in a couple of hours?

Assuming that 450 amp-hours was what was meant, those batteries should run a 75mA load for literally thousands and thousands of hours. Something is wrong with that guys setup, I think...

I have three alarms in my van. The smoke detector takes a 9V battery. A C0 detector and the propane detector is a Safe-T-Alert ( https://www.amazon.com/MTI-Industri...=8-3&keywords=safe+alert+propane+gas+detector " are tied to my house batteries. I have 350Ah of batteries and don't even give these alarms a second thought on battery drainage.

I'll hook it up tomorrow and see how much it drains my battery.

Understand mA must move the decimal point to the left to be amps. 450 mAmp = 0.0045 amp. What is that? One triple A battery?
