A digital camera battery is probably the most
important digital camera accessory. Some digital cameras can
consume power at an alarming rate, providing no more than a few
hours of continuous shooting time before the battery is drained.
Other cameras are renowned for the long life of their digital
camera battery which allows users to snap away with barely a
thought to power consumption. It is important to know how you
intend to use your camera and what type of battery it needs.
There are two types of digital camera battery.
The most widely available digital camera battery is a standard
AA-size battery. The other type of digital camera battery is a
rechargeable battery that is made by the manufacturer, otherwise
known as a proprietary battery.
A proprietary digital camera battery offers
the advantage of being lighter and more compact, but they are
substantially more expensive, making the prospect of buying one
or two backup sets much less appealing.
The alkaline AA-size digital camera battery
usually has a very short life - less than an hour in extreme
cases - when used in a digital camera. This type of battery
makes an acceptable emergency backup, especially if you are
travelling with your camera. However, the Nickel Metal Hydride (NiMH)
digital camera battery can be used instead of the alkaline ones
with a charger and this rechargeable NiMH digital camera battery
has a substantially longer life at an affordable price.
Another type of AA-size battery is the
non-rechargeable Lithium batteries and rechargeable Nickel
Cadmium (NiCD) batteries. The lithium digital camera battery has
a superior life to alkaline AA's and offers good cold-weather
performance but their price and non-rechargeable nature make
them less useful than rechargeable NiMH batteries. It is also
important to ensure that your camera can take a lithium digital
camera battery. On the other hand the NiCD digital camera
battery offers the advantage of retaining their charge while
unused, unlike NiMH cells, but have shorter lives and need to be
discharged completely before recharging which can be extremely
inconvenient.
The LCD screen of a digital camera is
responsible for consuming the most power from a digital camera
battery so it is worth only using the LCD when necessary to help
conserve the battery life. Always try to carry at least one
backup set of batteries, especially if you plan on being away
from power outlets for an extended period of time. The
universally-available alkaline AA-size battery can make a
convenient emergency backup if your regular digital camera
battery fails. |
