Good point. Sloppy wording.
"No calendar life limit, maybe."
ie they MAY not decay in capacity significantly without use. Or may.
I'm not sure as so far I have seen almost nothing at all on this
subject, whereas it's somewhat well discussed for other LiIon
chemistries.

The key difference between LifePO4 and other Lithium cells is that the
 LiFePO4 cell is based on an Olivine matrix which has very similar
volumes when fully chrged or depleted, so is not subject to much
mechanical cycling during charge / discharge cycles, whgereas most
other LiIon batteries are made from mush and wet noodles, or something
excessively like them. The battery beats itself to death mechanically
as it is cycled.
