Maxell CR2032 Lithium Cell: Early Failure

The Hobo datalogger buried in the dirt under the patio kvetched about a low battery, which produced this surprising result:

Maxell CR2032 cell – early failure

Cells from the same lot have been doing just fine in the other dataloggers, so I hope this is a one-off weak cell and not the harbinger of another run of dead cells.
