When inserted in the camera, EN-EL15b rechargeable Li-ion
batteries will charge while the camera is connected to a
charging AC adapter (the charging AC adapter cannot be used
to charge EN-EL15a and EN-EL15 batteries; use the supplied
MH-25a battery charger instead). An exhausted battery will fully
charge in about two hours and 35 minutes. Note that in
countries or regions where required, charging AC adapters are
supplied with a plug adapter attached; the shape of the plug
adapter varies with the country of sale.
