You'll be buying a new battery within 18 months.  Even when my Nook was new it didn't live up to the hi-pa of a long lasting battery charge, now I have to read plugged in. If you go on a camping trip of a few days, take a paper book!!! I've order a new bigger battery we'll see if I can actual get the new battery in without breaking the reader (you have to take the reader a part to change the battery, see YouTube).  B&N doesn't care batteries for their Nooks either, what's up with that!!!!
