Extending Battery Life; Rechargeable Batteries - HP Photosmart 850 User Manual

NOTE
If you do not intend to use your camera for

the camera.

Extending battery life

Use an optional HP AC adapter or HP Camera Dock when
unloading pictures to your computer, printing, or connecting
to the TV.
Use the viewfinder microdisplay to frame pictures instead of

camera is on.
Minimize the use of zooming.

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 turned off and is connected
to an optional HP AC adapter or HP Camera Dock. Batteries
are fully recharged via the optional HP AC adapter or HP
Camera Dock in 15 hours.
NOTE
You must turn off the camera when recharging the
batteries in the camera.
Some things to keep in mind when using NiMH batteries are:
Always recharge all four NiMH batteries at the same time.
One low-charged battery will reduce the battery life for all
four batteries in the camera.
