    Matches perfectly, connected simply, and working as crafted

    At first, I wasn't sure the battery was the issue with my alarm system. I had 6 devices on my system showing low battery. My system was a hybrid. Old ADT sensors on a Vivint system. Everything I did to try clearing the alerts didn't work. After lots of trouble shooting I figured since all six of those sensors were from the old system and were hard wired, that I'd try buying a similar battery as the one already In the junction box in my garage. Got the battery and it was a breeze to replace the old one with it. At first the low battery warning did not go away. On a whim I figured maybe the new battery just needed to sit in there for a while and charge. Thank goodness I was patient. On the second all of the Low Battery warnings cleared and I've not had any issues since.
