Furthermore it is weird that my kindle went utterly flat since it was full just a day before when i left it on the table and haven't touched it at all... unless the battery indicator is not accurate..
I do wonder though if there is a flaw in the K4NT that makes them so hard to charge up.. do you charge it uninterrupted for say 8 hours when you first got the device? does that help with the battery life?

Not a "flaw" just no battery management control software running.
If you "just left it sitting on the table" in diags mode - your battery should discharge to un-usable condition in less than 12 hours.

Both the LED indicator and the battery charger / battery management is under software control.
If your software is not running properly, neither is the controls.
Translation:
You can not trust the LED unless all things are normal.
The "charge for 8 hours" is based on using a low current charge source (USB port or USB charger) and covers re-charging the battery from the 70% charge level (which is how they ship) to a 90%+ level.
If you do not have a wall charger (high current charge source) then with a **good** Kindle, it may take 20 hours or more to re-charge.
With a **bad** Kindle, it will take somewhere between several days to never.
The above: **good** means operating normally, and **bad** means any other condition.
