Don't Use Alkaline AA - Use Rechargeables

Why you should use rechargeable batteries with your digital camera.

If your digital camera supports AA batteries, read the camera manual and check to see if it also supports a kind of battery called NiMH. These batteries tend to last much longer than most standard alkaline AA batteries - plus, they are rechargeable, so they can be re-used for quite a long time. Granted, the cost of four NiMH batteries plus a charger is more expensive than four alkaline batteries, but you'll more than make up the difference in costs once you recharge and use the batteries a few times.
