In fact, it??™s best to recharge most modern batteries somewhere in the
middle of their useful life. Don??™t top off a fresh battery. Nor should you wait until a battery
is completely exhausted, since that can affect its performance as well.
172 How to Do Everything: Digital Camera
Use Batteries in the Cold
You may want to run outside in the dead of winter to photograph snowmen, snowball fights, and
freshly fallen snow clinging to the trees. But because they??™re electronic devices, digital cameras
don??™t function as well in cold conditions as in the heat of summer.
You can prevent most problems, though, just by keeping your camera batteries warm. If the
batteries get too cold, the chemical reactions that generate power are inhibited, and they??™ll simply
stop working. Here??™s what I suggest: carry a spare set of batteries in your pocket, where your
body heat can keep them warm. If the current in the first set of batteries drops off due to the cold,
swap them out with the ones warmed by your body, and then continue shooting. Since the first
set of batteries will recover some of their charge when you stick them in your warm pocket, you
can swap back and forth a few times??”unless you??™re shooting in the Arctic where the ambient
temperature is 50 below zero.
