Casio QV-R51

Power is supplied by a pair of standard AA type batteries, NiMH rechargeable type is supplied and highly recommended. The approximate battery life with the supplied NiMH batteries is: 900 shots (2 hour 30 minutes), continuous playback 250 minutes. Test conditions: 74°F, LCD on, flash off, continuous recording.

Casio includes a healthy set of 2100mAh NiMH rechargeable batteries and the compact BC-5H battery charger. You can use alkaline type batteries in a pinch but they won't last nearly as long as the rechargeable type, possibly as low as only 20 shots!
