• 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.
