Keep in mind that a hardwired 12v detector will constantly draw on the battery. Not a lot, but enough to kill a battery in a couple weeks.
Absolutely NOT.
The typical RV propane detector pulls about 10 milliamps. That is 0.01 amps or 0.24 AH/day. So it will pull about 40 AH in 6 months. That is about a 50% draw on a single small RV battery.
My Safe-T-Alert combo CO/Propane detector is rated at 108 mA nominal current draw. So at that rate it will draw around 2.6 AH/day or 36 AH in 2 weeks.
