● Tips for Prolonging Battery Life
• Use the / button to turn off the flash when you are not
using it.
• You can also use the power save settings (E-43) to protect
against wasting battery power when you forget to turn off the
camera.
● Alkaline Battery Life
The actual life of alkaline batteries is affected by a variety of fac-
tors, including the battery manufacturer, the amount of time the
batteries spend in storage before you use them, temperature
while you are recording, and photographic conditions. As a rule,
we recommend the use of lithium batteries or Ni-MH batteries,
which have longer lives than alkaline batteries.
The following examples show how alkaline battery life changes
under different conditions.
Example 1: Intermittent use of the camera shortens battery
life.
Conditions
• Temperature: 25

C
• Repeat of a cycle of recording of one shot per minute for
10 minutes, followed by one minute of playback, and a
nine minutes of power off (power on, full lens extention,
half lens contraction, full lens extension, image recording,
power off)

Standard Battery Life
This camera can be powered by AA-size alkaline, lithium or Ni-
MH batteries.
The battery life reference values given below indicate the
amount of time at standard temperature (25
°
C) until power auto-
matically turns off due to battery failure. They do not guarantee
that batteries will provide the amount of service indicated. Bat-
tery life is reduced by low temperatures and continued use.
• The above figures 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.
• Figures are based on continuous recording under the following
conditions.
Flash turned off
One ZOOM slider switching between T (Telephoto) and W
(Wide-angle)
Recording one image per minute under the above conditions re-
duces 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.
