891 Battery Endurance
To ensure that you get the most from rechargeable Nikon EN-EL18d
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-EL18c, EN-EL18b, EN-EL18a, and EN-EL18 batteries can also be used.
Note, however, that fewer pictures can be taken on a single charge than
with the EN-EL18d.
