A Managing batteries
Your camera uses a rechargeable HP Photosmart R07 Lithium Ion battery (L1812A/L1812B).
Top points about batteries
Always insert the battery in the camera correctly (see “Install the battery” on page 6). If the battery
is inserted improperly, the compartment door may close but the camera will not operate.
• New rechargeable Lithium Ion batteries are shipped partially charged. Fully charge them before
first use.
• If you do not intend to use your camera for more than two months, leave the camera connected
to AC power using the power adapter that came with your camera. The camera will top off the
battery periodically to ensure that the camera is always ready for use.
• A rechargeable Lithium Ion battery can be left in the camera or optional dock or quick recharger
for any period of time without harm.
• If a rechargeable Lithium Ion battery has not been used for more than two months, recharge it
before using it again. Fully recharge Lithium Ion batteries every six months to a year to prolong
their useful life.
• The performance of Lithium Ion batteries degrades over time, especially if stored and used at
high temperatures. If battery life is unacceptably short, replace the battery.
• The performance of Lithium Ion batteries will decrease as the temperature drops. To improve
battery performance, store the camera and batteries in a warm inside pocket when in a cold
environment. To prevent short-circuiting the batteries, never carry small metal items such as
keys or coins in the same pocket with your batteries.
Extending battery life
To conserve battery power, the Image Display turns off after 45 seconds by default. For the R840
series, the Image Display also automatically dims and brightens based on lighting conditions.
Pressing any button wakes up the camera. After five minutes of inactivity, the camera turns off.
To further extend battery life:
•
Set Display Brightness to Low (see Display Brightness under “Using the Camera Setup
Menu” on page 38).
•
Change the Display Timeout value to a shorter interval (see Display Timeout under “Using
the Camera Setup Menu” on page 38).
•
Set your camera to Auto Flash (see Auto Flash under “Setting the flash” on page 15).
• Use optical zoom sparingly.
•
If you are turning on the camera only to view images, slide
to , then turn on the
camera to start in
Playback without zooming the lens.
• When printing directly to a PictBridge-certified printer, place your camera in an optional
HP Photosmart dock connected to AC power.
Safety precautions for using batteries
• Do not place the battery in fire or heat the battery. Always store charged batteries in a cool
location.
• Do not connect the positive and negative terminals of the battery to each other with any metal
object.
• Do not carry or store the battery with metal objects. Do not drop the battery into a change-filled
pocket.
• Do not pierce the battery or subject it to strong impacts or shocks.
• Do not solder directly onto the battery.
• Do not allow the battery to get wet.
