Q: 2. Is this battery "chipped", so you don't get an error message when you try to use it?

A: The Watson EN-EL15c Lithium-Ion Battery Pack (7V, 2250mAh) (B&H# WAENEL15C) does indeed contain an IC chip that will result in operation that, from the user's perspective, is identical to that of a Nikon EN-EN15c in most common cases. However, in some cases manufacturers can issue firmware updates that can make the operation of any third party battery different such as requiring the user to click "OK" on the screen to use it. At this time (November 2021), it will power any Nikon camera that takes the Nikon EN-EL15, EN-EN15b, or EN-EL15c. That includes the latest such cameras from Nikon (i.e. the Z 6II and the Z 7II), as well as earlier models. You can click the [COMPATIBILITY] button on this webpage to see an updated list.
