Trying to get GD00Z DH to report battery level

I am trying to fix my device handler for the GD00Z-4 garage door opener. It doesn’t report batter level and I can’t figure out what command class to use to get the device to report the level.

According to the zwave alliance the battery status command class isn’t offered. I don’t know if Powerlevel should work but I have tried it in the past and performing a Get doesn’t result in a reply.

Anyone know what command class this device supports for batter level?
