I have Ring Security System 2nd Gen. 3 of my window sensors loose battery very fast, within 4-5 weeks. These windows are hardly ever opened. I never had this issue with the security systems (ADT and Xfinity) that were installed previously in my house, the batteries in their sensors lasted over the 3 year contract I had with each of them. Are the sensor’s bad? I have 14 sensors in my house only 3 have this issue.
Please review my post from last week. I had the identical issue, called support and replacements are on the way. They did trouble-shoot and decided they were faulty. In fact, one totally died after multiple battery replacements. Prior to calling make sure you do not have the Red low signal alert on each of those sensors, as that will drain batteries as well.
