If the Kobo is turned off, it should be able to maintain a storage charge for a *long* time. Unfortunately, there is no way to power off Kindles, so they will run down and need periodic charging. Although so far, all the readers I have let run flat, Kindles and Kobo's, have successfully powered themselves off when battery is low enough to prevent any immediate battery killing damage, (in truth, no sane LiOn powered device should ever allow you to actually run battery completely empty.)

It is ABSOLUTELY FALSE that keeping a lithium-based battery at 100% will damage it. That's because ALL such batteries have a mechanism which turns off the charging once it becomes fully charged.
Here's a YouTube video from Dell which says just that (@ 1:20 of the video). It deals with laptops but it applies to all battery-powered electronics devices.

FWIW, that's a myth left-over from the last-gen batteries which where nickel-based.
