Appendix A: Managing Batteries 135
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:
z The first time that you use a set of NiMH batteries, be sure
that you fully charge them before using them in the camera.
z 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.
z 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.
z 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.
z The performance of all rechargeable batteries, including
NiMH, will degrade over time, especially if they are stored
and used at high temperatures. If battery life has become
unacceptably reduced over time, replace the batteries.
