A 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-7 are used.
The
following measurements were performed using a fully-charged
EN-EL15 battery (1,900 mAh) at a temperature of 23 °C (73.4 °F) while
continuously uploading images with an average file size of
5.3 megabytes (equivalent to a large normal-quality JPEG image taken
with the D500) to an ftp server configured using Internet Information
Services (IIS) under Windows 8.1 over an infrastructure network with the
WT-7 in FTP upload mode (all figures are approximate).
Network Wireless (802.11ac) Ethernet (1000BASE-T)
No. of shots uploaded 35,000 100,000
Battery life 240 min. (4 hr.) 390 min. (6.5 hr.)
To ensure maximum battery performance:
• Keep the battery contacts clean. Soiled contacts can reduce battery
performance.
• Use EN-EL15 batteries immediately after charging. Batteries will lose
their charge if left unused.
• Periodically check the battery level using Network > Options >
Battery info.
• The battery level displayed by the camera may vary with changes in
temperature.
• A sharp drop in the length of time the battery can hold a charge
indicates that the battery must be replaced.
