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–35 °C
(41 °F–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.
Battery capacity may temporarily drop if the battery is charged
at low temperatures or used at a temperature below the temperature
at which it was charged.
If the battery is charged at a temperature
below 5 °C (41 °F), the battery life indicator in the Battery info (0 374)
display may show a temporary decrease.
