ABattery 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.

Network	Wireless	Wireless	Ethernet
	(802.11a)	(802.11g)	(100 base-TX)
No. of shots uploaded	4,500	4,500	10,000
Battery life	150 min. (2.5 hr.)	150 min. (2.5 hr.)	200 min. (3.3 hr.)

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.
