Digital Camera 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
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
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.
