Battery Life
The length of time batteries can be used and the number of shots that can
be uploaded before recharging varies with the condition of the batteries,
signal strength, and how camera and WT-4 are used. The following
measurements were performed using a fully-charged EN-EL3e battery
(1500 mAh) at a temperature of 23 °C (73.4 °F) while continuously
uploading images with an average file size of 3 Mbytes to a host computer
running Windows Vista Ultimate over an infrastructure network with the
WT-4 in transfer mode.
To ensure maximum battery performance:
• Keep the battery contacts clean. Soiled contacts can reduce battery
performance.
• Use EN-EL3e batteries immediately after charging. Batteries will lose
their charge if left unused.
• Periodically check the battery level using [Wireless Transmitter] >
[Device info] > [Battery info].
• The battery level displayed by the camera may vary with changes in
temperature.
