200 Technical Notes
• Remove the battery from the camera or charger when not in use and
replace the terminal cover. These devices draw minute amounts of
charge even when off and could draw the battery down to the point
that it will no longer function. If the battery will not be used for some
time, insert it in the camera and run it flat before removing it from the
camera for storage. The battery should be stored in a cool location with
an ambient temperature of 15 °C to 25 °C (59 °F to 77 °F; avoid hot or
extremely cold locations). Repeat this process at least once every six
months.
• Turning the camera on or off repeatedly when the battery is fully
discharged will shorten battery life. Batteries that have been fully
discharged must be charged before use.
• The internal temperature of the battery may rise while the battery is in
use. Attempting to charge the battery while the internal temperature is
elevated will impair battery performance, and the battery may not
charge or charge only partially. Wait for the battery to cool before
charging.
• Charge the battery indoors at ambient temperatures of 5 °C to 35 °C
(41 °F to 95 °F). Do not use the battery at ambient temperatures below
0 °C (32 °F) or above 40 °C (104 °F); failure to observe this precaution
could damage the battery or impair its performance. Capacity may be
reduced and charging times increase at battery temperatures from 0 °C
(32 °F) to 15 °C (59 °F) and from 45 °C (113 °F) to 60 °C (140 °F). The
battery will not charge if its temperature is below 0°C (32 °F) or above
60 °C (140 °F).
• If the CHARGE lamp flashes quickly (about eight times a second) during
charging, confirm that the temperature is in the correct range and then
unplug the charger and remove and reinsert the battery. If the problem
persists, cease use immediately and take battery and charger to your
retailer or a Nikon-authorized service representative.
• Do not move the charger or touch the battery during charging. Failure
to observe this precaution could in very rare instances result in the
charger showing that charging is complete when the battery is only
partially charged. Remove and reinsert the battery to begin charging
again.
