What is the difference between the supplied battery pack NP-BN from the optional battery pack NP-BN1?

The NP-BN is specially designed for camera models for which it is supplied. There is no difference from the optional NP-BN1 in terms of the battery performance and battery life.

NOTE:

• The NP-BN battery pack cannot be used with a camera for which it is not supplied.
• When using the optional battery charger BC-TRN, quick charging is not available. If you need to charge the battery quickly, use the BC-TRN2.
