Hee... But the first few runs with new batts got me worried... but after allowing the batts some muscle flexing all's great... and Hey, Dpreview said 1 set of well charged GP1600 is good for for over an hour of shooting~ Over a hundred shots~ But well, It does seems not to be able to last as long as some other cameras that uses AAs, such as the Casio QV-4000... But I feel It No problem. Just make sure you get a good charger and keep the batteries in top form.
