This particular camera has a Li-ion battery with some good image stabilization and 3x optical zoom:

Wis one uses AA (I know you said you didn't necessarily want that), which you can also get some adapted battery packs, one being the CRV-3 that will last a little longer than the standard AA. Additionally, it has 5x optical zoom for a little more flexibility with your shots:
