I know the current generation of batteries aren't supposed to do this, but old habits die hard.

The Li-Ion batteries in the Sony Readers dont have the memory effect that NiMH batteries 'suffer from.'
Current 'thinking' advises recharging Li-Ion batteries well before they have fully discharged, as it can prolong the battery life and keep it at near new capacity through most of its lifetime.
IME of using Li-Ion batterries for various electronic 'toys' I have recharging them when at 25 - 50% capacity has made them last years.
I have 3 batteries for my Sony Digital Camera that were bought in 2003, and they still chrge to near new capacity. (I get the same number of shots per charge for each battery after 8 years as I did when the batteries were new)
My iPod 5th gen Still gives me the same 'play time' between charges that it did when new (in 2006)
I (try to) recharge the Li-Ion batteries in all my 'toys' when the battery is between 25 - 50% of capacity.
It's not just to make the battery last longer, it also means it performs best when it's 'looked after.' You get no surprises of finding a dead battery when you want to use the "E-Reader, Camera, iPod, Phone, etc."
Some reading on care and maintenance of Li-Ion batteries.
