LP liquid propane sensor keeps going off when battery level is at 11.6 volts

When out dry camping my LP sensor goes off when the battery level is at 11.6 volts

My suggestion...never ever let your battery get down to 11.6V.

Your detector is going off because you have discharged your battery by 90%. It is a wonder that anything 12 volt is still working. That will destroy a battery in no time at all.

That alarm is telling you that the voltage is too low for the CO/Propane detector to work properly. You are also damaging your battery as well as mentioned above.

Cool chart which explains why my lights go out when my battery voltage goes down to 10.5 volts.

You may ,
1. Have a bad battery.
2. need more batteries for your boondocking style.
3. need to add solar or buy a generator to replace battery power.
How many hours/days are you trying to boondock and what are you running in the RV?
