Hmmm.
Some time ago, I was on the trainer zwifting my heart out, and one of my cats jumped up on the table next to me. He picked up a used CR2032 battery and ran behind some shelving with his prize. I wondered if the bitter coating was going to disappoint him. I haven't bothered to move the damned shelves to recover the battery.
