Fibaro Flood sensor Batterie issue

Hello dear community

I have 2 Fibaro Flood Sensors. Both are connected to my Smartthings Hub via Edge drivers (Z Wave sensor driver). After a week both sensors show below 10% battery. However, this 10% then lasts two to three weeks until it jumps to 1%. I almost don’t believe that the batteries are empty. I put one back in after a week, which was at 1%, and the Smartthings app showed 25% again.

Does anyone have any idea what the problem could be?

Thank you very much

Probably an old battery that is shot. Have you tried a fresh battery?

IT Happens with different new batteries

Mine just migrated from DTH to Edge…I’ll keep a eye on the battery levels and see if I have any issues.
