Batteries

Digital Camera Batteries are something you simply can’t do without if you have a digital camera.

Because a digital camera is essentially a mini computer, it must have a constant source of power to run on. While power can come from a power cord, most of the time, batteries are the most convenience source. Digital cameras can use one or more of the following batteries:

– AA cells
– non-rechargeable alkaline
– rechargeable nickel metal hydride (NiMH) or Nickel-cadmium (NiCd)
– high-capacity disposable CRV3s
– proprietary rechargeable batteries

The internal electronics of digital cameras can really suck up power. Many digital cameras can drain a set of AA cells in 30 to 40 minutes. More demanding cameras can’t run from alkalines at all because they draw so much current. These cameras post a warning in the manual that the use of alkaline batteries is not recommended. They can cause your camera to shut down unexpectedly. Lithium AA cells can last two to three times longer than alkalines but cost three times as much.

Nickel-cadmium (NiCd) and nickel-metal-hydride (NiMH) rechargeables hold their charge even less time than alkalines and lithiums. However, they handle high output currents much better than primary cells. And since you can use them over and over again, they are also much cheaper in the long run. Recharging takes a few hours so it’s advisable to have more than one set of charged batteries on hand if you’ll be taking pictures for several hours.

The type of battery you choose may depend on the manufacturer’s recommendation coupled with your needs and lifestyle. Some people prefer a camera that accepts standard- sized batteries. That way they can always find replacements anywhere they travel. Others prefer proprietary rechargeables because they can be recharged repeatedly and are recommended for their camera.

The main thing to remember is that rechargeables save money in the long run.

Once you have a camera, batteries and a memory card, you’re going to have images to print! In the next lesson we’ll talk about the 3 steps to digital picture printing. One of them is the question I’m asked most (next to which camera to buy), and that’s how to change the size of the picture.
