I am getting a chirping sound in my T@B CS max. It started after winterizing. I put a charged battery in and after a few days the display on the Jensen radio went dark. When connected to towing vehicle showed 13.4v charging. Battery read 12.8 v.
i have taken the battery out for the winter and chirping is still happening. Is there a battery in the co/ smoke detector? How would I change it.
