Amazon says 2 weeks with wireless turned off. I don't know how much of that is active use vs standby. It might be longer if you're not using it at all.
However, there is a difference between how long to wait before you need to charge the battery to keep it from going dead, vs how long to wait before you need to charge the battery in order to preserve it's long term life expectancy.
I don't know what type of battery the Kindle has off the top of my head, but most of these devices typically have a lithium-ion battery (or a variant of one). These types of batteries do better if you don't wait until they're fully drained before charging them. A big charge cycle like that can actually reduce their life expectancy. It's better to top them off more frequently, requiring a smaller charge cycle, and only let them fully drain once in awhile in order to keep the meter calibration from drifting. Personally, I would only let it get down to about 50% - 60% before charging, then after doing that 30 or so times, let it drain completely once, then start topping off for 30 times again... etc.
