بطارية ليثيوم أيون Promaster لـ Nikon EN-EL15c

Bought this as a backup for my Z6 and the battery indicator reads full after a quick charge, just like the original. It's dropped right into the charger without any fit issues, and I've already gotten through a full day of shooting without a hiccup.

Popped it in my Z6 II and it registered the full charge immediately, no error messages. Been shooting a wedding all day and it’s still at 40% — easily matches my original Nikon EN-EL15c in runtime.

Pulled it out of the box, popped it in my Z6 II, and the camera recognized it instantly with no warning messages. Been shooting all afternoon on one charge and the battery meter barely moved. Solid build, fits snug, and for the price it's a no-brainer backup.
