I got a bunch of batteries cheap and I change my hygrometer batteries every 3 months just to be safe...

Actually, now that I think of it. I tried replacing the battery in one with no improvement, so I just put the old one back one. No difference.

Will confirm with the calibration bag that will be here this weekend. Put them in my old calibration bag that "expired" in December and they were reading 78-80%.
