A Managing Batteries
Your camera uses two AA batteries. For best results, use
Energizer Lithium AA or rechargeable Nickel Metal Hydride
(NiMH) AA batteries. Alkaline batteries provide far less
battery life than Lithium or NiMH batteries.
Top Points About Batteries
• The first time that you use a set of NiMH batteries, be sure
that you fully charge them before using them in the
camera.
• If you do not intend to use your camera for extended
periods of time (more than two months), HP recommends
that you remove the batteries unless you are using
rechargeable batteries and are leaving the camera
docked or connected to an optional HP AC power
adapter.
• When inserting the batteries in the camera, always be
sure to orient the batteries as directed by the markings in
the battery compartment. If the batteries are inserted
improperly, the compartment door may close but the
camera will not operate.
• Never use batteries of different chemistries (for example,
a Lithium battery and NiMH battery), brands, or ages.
This can cause erratic camera behavior, as well as
battery leakage. Always use two identical batteries of the
same chemistry, brand, and age.
