Battery Packs: Power for Cameras, Electronics and More
Battery packs power many portable devices. Cameras, computers, RC models and
power tools are a few. Some power packs are external while others fit inside the
device. Here we are going to focus our attention on how these power packs are
used in Cameras and other photo devices.
Batteries Used in Photo Devices
Film cameras use a variety of battery sizes and styles. Some of these batteries, especially
for older cameras, are getting harder to find. Fortunately there are web sites
specializing in rare photo batteries. In some cases an external power pack is
ideal, and for others a custom battery pack can replace the original battery.

Digital cameras typically employ either a rechargeable battery pack or
standard AA's. Many Prosumer and digital SLR cameras use battery packs. Specs vary but
many newer lithium ion packs can be recharged in a couple of hours
or less and will take hundreds of shots. AA batteries are common in compact
digital cameras. While replacements are readily available, it can quickly become
rather expensive.
External flash and remote control units employ various
types of batteries. Here again, throwaway batteries can get expensive and
frustrating.
Time and Money Saving Battery Tips
If the camera, flash or remote uses standard or specialty disposable
batteries, a wise investment is rechargeable
batteries. Technically not battery packs, they serve the same function of
supplying power without constantly buying new batteries. Lithium ion (Li-ion) and Nickel Metal Hydride (NiMH) batteries are best. They are less prone to the
so-called "memory effect" of older Nickel Cadmium (NiCad) batteries, and last longer per charge than throwaway alkaline batteries.
Whether individual batteries or a battery pack, get the highest mAh rated rechargeable batteries you can find - preferably 1600 mAh or
more. They cost a little
more but are well worth it in the long run. Also buy a good charger and at least
one extra set of batteries.
With an internal battery pack you're pretty much stuck with the battery
designed for the camera or other photo device. Look for upgrade options, but
also check the specs and professional reviewer comments for expected life per charge. Even with the best
photo batteries or battery pack, at least one
fully charged back-up is recommended.
Regardless of the battery type, a little research before you buy will save
time and money plus a lot of frustration, making your photo experience
more enjoyable.
