To ensure that you get the most from rechargeable Nikon
EN-EL15b 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-EL15a/EN-EL15 batteries can also be used. Note, however, that
fewer pictures may sometimes be taken on a single charge with the
EN-EL15 than with an EN-EL15b/EN-EL15a.
