kwikset door lock battery status

during my last upgrade i had to rebuild my z-wave database from a backup. i was able to get all devices functional but for some reason the battery status no longer appears for my kwikset door lock. i checked the device type and it has the correct associated device type I think?

device _type urn:schemas-micasaverde-com:device:DoorLock:1
device_File D_DoorLock1.xml
device_json D_DoorLock1.json

should there be a variable for battery status?

my lock is functional. I have scene setup to disable the alarm and turn on lights when the door is unlocked etc but no battery status. Anyone have any suggestion. I would prefer not to exclude and re-include as I have issues with the security association in the past and how long it takes to pair.
