ST Motion Sensor Battery

Ive had my ST motion sensor for 6 months with no issues. Since the latest update, Ive been having a few issues with my sensor freezing in active mode toward the evening. The battery shows 89%. Ive had to reset the battery twice to get it working again. So far so good for the last two days. The battery I pulled out was a CR2450. Something Ive noticed in my testing, that there is a warning to only use Duracell or Panasonic batteries. Now in the past this has been mostly BS. However, there is a lot of new technology floating around to determine battery type and brand. Anyways, when I put a brand new Energizer CR 2450 in there it would not function. I put the old battery back in and working again. Tested voltage on both batteries. New: 3.5V Old: 3V. Can anyone confirm that we must use Duracell or Panasonic brands only? If this is not the case, what could the problem possibly be.

I believe it is down to the profile of the battery…

This is correct… some CR2450s have an oddly tapered edge that does not hit the contacts in the sensor. If the sensor is regularly losing connection, but isnt moving - you may want to try enabling Zigbee Insecure Rejoin.
