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
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.
