ID Lock 150 - Z-wave + battery drain issues

Devices
1

After adding a z-wave module to my ID Lock 150 (FW 1.5.9) i’m having battery drain issues.
The battery will last for a maximum of 4 days beforce being completely depleted.

So I removed the z-wave module, but the battery are still being drained! Even with the module removed, battery will still be empty after 4 days.

Any tips?

I have no problems at all, but i use lithium batteries.
Lasts around 10 months.

@Moinge Did you solve the issue with the battery draining issues? My ID Lock 150 with latest fw has been working fine for years but all of a sudden needs new batteries once per week.
I have even removed the zwave module just to see if it made a difference but no difference so far.
