HP Photosmart M22/M23 User’s Manual
When the HP AC adapter is used to charge the batteries and
the camera is off, the Power/Memory light on the back of the
camera will blink during charging. When the dock is used,
the dock light will blink. When the quick recharger is used,
the light on the quick recharger will be red to indicate
charging.
If you will not be using your camera immediately after
charging the batteries, we recommend that you leave the
camera in the dock or plugged in to the HP AC adapter. The
camera will top off the batteries periodically to ensure that
the camera is always ready for use.
Some things to keep in mind when using NiMH batteries are
as follows:
• The first time that you use a set of NiMH batteries, be sure
that you fully charge them before using them in the
camera.
• You may notice that the first several times you use NiMH
batteries, the battery life seems shorter than what you
expect. Performance will improve and become optimal
after the batteries have been charged and then
discharged (used) completely four or five times. You can
use the camera normally to discharge the batteries during
this conditioning period.
• Always recharge both NiMH batteries at the same time.
One low-charged battery will reduce the battery life for
the other battery in the camera.
• NiMH batteries discharge when not in use, whether they
are installed in a camera or not. If they have not been
used for more than two weeks, recharge them before
using them again. Even if you are not using your
batteries, it is a good idea to charge them every six
months to a year to prolong their useful life.
