To ensure that you get the most from rechargeable Nikon
EN-EL15c batteries:
•
Keep the battery contacts clean. Soiled contacts can reduce
battery performance.
•
Use batteries immediately after charging. Batteries will lose
their charge if left unused.
1 EN-EL15b/EN-EL15a/EN-EL15 batteries can also be used. Note,
however, that fewer pictures can be taken on a single charge than
with the EN-EL15c.
