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-EL15 battery.
Charge the battery before use.
When taking photographs on important occasions, ready a
spare EN-EL15 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.
