Kwikset 914 Z-Wave lock battery reporting frequency

I have two Kwikset 914's in a second home. One reports battery level about 2/day, and one is reporting battery levels every 15 minutes.

The latter is way too much. I would prefer 1-2 /day at most. I cannot, however, figure out how to change that parameter. I am using the 'Generic Z-Wave Lock' device handler. Everything about it works great but if someone knows how to change battery reporting interval please let me know!

Not that I know how to change the interval, I have two 914 and one 916, they all report battery level every 30mins.
