10.1 Batteries
Most manufacturers suggest removing the camera (and portable GPS)
batteries if the camera/GPS is not used for two weeks or longer. Even modern
batteries can leak or corrode (especially when discharged), and sometimes small
amounts of this material can coat the electric contacts, which can render the
camera inoperative.
Don’t mix fresh and used batteries in the camera, and don’t mix different kinds
of batteries (e.g., two regular alkaline and two rechargeable batteries, or to NiMH
and two lithium ion rechargeable batteries).
Be careful to insert the batteries (+ and - ends) according to the camera’s
polarity diagram, which is usually depicted on the inside of the battery cover.
When you insert batteries, turn on the camera – it should start normally and
shows a full charge. Otherwise, turn off the camera and check that the batteries
are inserted properly.
Don’t leave batteries plugged into a battery charger; once the batteries have
been fully charged, remove them from the charger and store them at room
temperature.
Use a charger that is designed for the battery: NiMH batteries should only be
charged in a charger designed for NiMH batteries, and high-capacity batteries
need a high-capacity charger.
Use standard chargers rather than “rapid” chargers; rapid chargers tend to
undercharge batteries by as much as 20%. Choosing the wrong charger can
make a big difference; the worst chargers (in terms of completeness-of-charge)
produce "charged" batteries with only half the stored energy of ones charged with
the best chargers.
Once charged, Lithium Ion batteries don’t lose very much of their power while
being stored; single-use Lithium Ion batteries are essentially unaffected by sitting
unused for several years. However, NiMH batteries don’t maintain their charge as
well; their charge gradually dissipates while sitting on the shelf. Get in the habit of
recharging batteries when you’re done shooting, and always have at least two
fully-charged sets of batteries: one in the camera and one in the camera bag so
you’re always ready for a mission. Also, it is best to charge batteries as a set so
that they grow old together.
Use the AC adapter when you perform extensive editing on pictures stored in
your camera or when you’re downloading your photos through the camera’s cable
connector.
Assign someone to check the batteries and charge them as needed (maybe
in conjunction with one of your periodic meetings).
10.2 Lenses and LCD/Viewfinder
The lens, LCD, and viewfinder must be kept clean and protected from
scratches. Ensure lens caps are kept in place anytime the camera isn’t being
used, and that the cap is secured to the camera with a strap. Cleaning supplies
(as recommended by the manufacturer) should be kept in the camera bag.
