RV Repair: lpg gas detector, gas detector, battery alarm

Question
My lpg gas detector is chirping like the start of the "low battery" alarm.  My battery is fully charged and all of the other 12v appliances are working fine.  The reset button has no effect.  It makes a different noise for a gas leak and the hand held gas detector shows no sign of gas.  Is there something else I need to check or should I just replace this detector?

Answer
Maureen,
       I have had customers (and a few technicians) mistakenly think the chirping from the smoke detector low battery was coming from the LP leak detector.  If you are positive it's the LP leak detector then yes I would replace it.  I hope this helps.
