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.
Continuing to charge the battery after it is fully charged can impair
battery performance.
A marked drop in the time a fully charged battery retains its charge
when used at room temperature indicates that it requires replacement.
Purchase a new EN-EL20 battery.
Charge the battery before use.
When taking photographs on important
occasions, ready a spare EN-EL20 battery and keep it fully charged.
Depending on your location, it may be difficult to purchase replacement
batteries on short notice.
Note that on cold days, the capacity of
batteries tends to decrease.
Be sure the battery is fully charged before
taking photographs outside in cold weather.
Keep a spare battery in a
warm place and exchange the two as necessary.
Once warmed, a cold
battery may recover some of its charge.
Used batteries are a valuable resource; recycle in accord with local
regulations.
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 may increase at battery temperatures from
0 °C (32 °F) to 10 °C (50 °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).
