There are a couple types of disposable lithium AA batteries out there. I had good luck with the Energizer Ultimate Lithium batteries (silver wrapper with a blue stripe) in my K-30, but didn't have much luck with a cheaper set of disposable lithium AAs... the cheaper ones didn't seem to have enough juice to power the camera for very long.
As for pre-charged rechargeable batteries... they tend to slowly drain over time. Unless you got a really fresh set, they may have already reached the point of needing to be charged. Modern digital devices are very sensitive to under-voltage power supplies and it doesn't take much for a battery to drop below that "magic" voltage particularly when you start pulling power out of it.
