Contact sensor 2nd gen battery keeps draining

I have 5 contact sensors and all of them are fine but one. The battery drains really fast and for about two days prior to a dead battery it will go from low battery to full battery back and forth until it is completely drained. Ive replaced the batteries on that sensor 5 times in the last month and a half. The other sensors are still at full. Ive even swapped the sensors around thinking it was the location i had it at and still same thing. It’s frustrating and annoying

Hi there, @Arguijom86! You’ve covered all the best steps here, and thank you for sharing these details. I recommend factory resetting your Contact Sensor following the steps in this help center article.

If this concern persists, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.

First, swap the sensor with a sensor that isn’t exhibiting the behavior. Does the behavior persist? If the behavior persists with the new sensor in the old location then how far away is the sensor from a Z-Wave extender or the base station?
