Kodak's Monthly Tech Brief Removes the Milli-Amp Mystery of Digital Camera Batteries

ROCHESTER, N.Y.--Feb. 2, 2005--Baffled by batteries? If you're one of the millions of newcomers to digital photography, you may find more than a few choices when you're looking for batteries to power your digital camera.

Kodak's Monthly Tech Brief offers ideas to help power up your picture taking. Just as you choose a car or bus for a short trip, or a jet or train for longer travels, you can select batteries that meet different picture-taking needs.

If your digital camera uses AA-size cells, you can choose from several chemistries to meet different needs. Rechargeable Ni-MH AA batteries are your best overall value. In addition, Ni-MH cells are better for the environment and require no special handling.

When choosing rechargeables, check the fine print. Most AA-rechargeables have a milliamp-hours (mAh) rating; the higher the number, the longer a battery will perform between rechargings. A 2500-mAh battery, such as the KODAK Ni-MH Rechargeable Digital Camera battery, will last longer than an 1800-mAh battery.

In terms of performance in a digital camera, owners of cameras taking two AA-size cells have many choices. The CRV3 lithium battery (a non-rechargeable) yields the most pictures. Next longest lasting in a digital camera is the KODAK Ni-MH AA Rechargeable Digital Camera battery (KAARDC), a 2500-mAh battery. Many KODAK EASYSHARE digital cameras also accept the KAA2HR Ni-MH Battery Pack (2100 mAh each) that delivers next-best life among KODAK Ni-MH AA cells, and allows in-camera charging from a KODAK EASYSHARE printer dock or camera dock.

Another option: Oxy-Alkaline AA batteries. A change in battery chemistry enables these batteries to last longer than conventional alkaline batteries, making these non-rechargeables ideal when you're camping, sailing, or hiking. Oxy-Alkaline batteries - while not as long-lived as the lithium or rechargeable cells - outperform alkaline cells at a comparable cost.

To make all your batteries last longer, use your camera's viewfinder when the LCD screen isn't necessary, and switch off the display, rather than fully powering down your camera.
