Lithium batteries do NOT like to be overly discharged. Nor should they be stored with a full charge. For storage or safe transport, 40 to 50% charge is good (but no more than 70%).

In fact, for mission-critical batteries (such as used in military/police/fire/medical equipment), they are never charged past 70% of an otherwise identical "consumer device" battery, for maximum lifespan.

The kindles even have a "shipping mode" script, that DISCHARGES the battery to below 70% (which can also be done in the kindle diagnostic menus).
Would be nice to amend the charging params so that 70% = 100%

I would hate to have to constantly unplug them. This would be a better solution...

Hmm. Wonder where one might go about achieving that?
