Thanks all for your input. I have received many good comments and plan to use them. As I've mentioned before in many of my posts, this forum is awesome and I respect the people who take the time to reply in a professional manner. Thank you!
Some of you have posted about my batteries and the low voltage being the problem. I got it and thank you...I agree that's not ideal. But I also believe the Boost cycle (14.5 v) of my smart charger takes care of the sulfation on the plates and helps extend the life of the batteries. I never would have found out about the CO/LP detector failing on the fringes if my batteries stayed at a healthy voltage above 12 vdc. My intent was to alert people of a potential design flaw and was hoping people would be interested and concerned that an important device like the CO/LP detector was not operating properly within the documented design specs. I also believe its a wide-spread problem and not just an issue with mine.
I already have a portable CO and LP detector placed in different locations around my camper but I was hoping to find a good quality detector and install it in the location where my current Safe-T-Alert detector is located.
Again folks, thanks for your input to this post. Cheers! .. and happy RV'ing!
