Rechargeable Batteries; Power Conservation - HP photosmart 930 series User Manual

Rechargeable batteries

Nickel Metal Hydride (NiMH) batteries can be recharged by
using a battery charger. NiMH batteries can also be recharged
in the camera when the camera is connected to an optional
HP AC power adapter or HP 8886 camera dock. Batteries are
fully recharged via the HP AC power adapter or camera dock
in 15 hours.
Some things to keep in mind when using NiMH batteries are:
Always recharge both NiMH batteries at the same time.
One low-charged battery will reduce the battery life for both
batteries in the camera.
For NiMH batteries to reach optimal capacity and
performance, they should first be discharged completely
and recharged four separate times.
NiMH batteries discharge when not in use, whether they are
installed in a device (such as in the camera) or not. If they
have not been used for more than two weeks, recharge
them before using them again.

Power conservation

To conserve battery power, the Image Display turns off
automatically if there is no button activity for 60 seconds. If no
buttons are pressed for 6 minutes, the camera turns off (unless
it is connected to a computer or printer).
