Promaster 鋰離子電池 適用於Nikon EN-EL15c 不適用於Z8、Zf、Z6III

I've been using these in my D500 for wildlife shoots and they last through an entire day of heavy shooting without dropping below half charge. The snug fit in the battery compartment gives me confidence they won't shift around during fast action sequences.

The battery indicator on my D750 shows a full charge even after a few days of sitting idle, which is a nice improvement over the old ones. It powers through a full day of shooting with plenty of charge to spare.

Was a bit skeptical about third-party batteries, but these ProMaster ones have been lasting just as long as my OEM Nikon EN-EL15c, even after dozens of charge cycles.
