Q: 10. Does this battery charger work with Nikon EN-El 14 A batteries - which power the newer Nikon cameras such as P7800 ( mine) or D5300 - or the older 14 battery for the P7100 , D 5200 etc.There is a difference in the battery designation and the way the camera talks to each battery...I found out the hard way that the older 14 battery will not work in a new 14-A camera. It should not affect charging but it surely affects usage.

A: Yes the Watson Compact AC/DC Charger for EN-EL14 Battery Charger will be fully compatible with the Nikon EN-EL14 A series battery.
