Battery Life Guidelines
The battery life guideline values given below indicate the
amount of time at standard temperature (25 C) until power
automatically turns off due to battery failure. They do not
guarantee that batteries will provide the amount of service
indicated. Low temperatures reduce battery life.
Type of Operation
AA-size Alkaline
Batteries LR6
AA-size Lithium
Batteries FR6
AA-size Ni-MH
Batteries NP-H3
• The above values are approximations only.
• The above guidelines are based on the following battery
types:
Alkaline: MX1500 (AA) DURACELL ULTRA
Lithium: Energizer
* Battery life varies with brand.
• Values are based on continuous recording under the fol-
lowing conditions.
— Flash turned off
— One switch between telephoto and wide-angle with the
zoom controller per image

— Recording one image per minute under the above con-
ditions reduces battery life to about one sixth of that
noted above.
• Battery life is greatly affected by how much you use flash,
zoom and other functions, and how long you leave power
turned on.
Tips for Prolonging Battery Life
• Use to turn off the flash when you are not using it (page
E-55).
• You can also use the power save settings (page E-35) to
protect against wasting battery power when you forget to
turn off the camera.
• You can also conserve battery power by using DISP to turn
off the monitor screen.
Alkaline Battery Life
The actual life of alkaline batteries is affected by a variety of
factors, including the battery manufacturer, the amount of
time the batteries spend in storage before you use them,
temperature while you are recording, and photographic con-
ditions. As a rule, we recommend the use of lithium batteries
or Ni-MH batteries, which have longer lives than alkaline bat-
teries.
