Compatible batteries

Genuine means made by the camera maker. Third-party cells are cheaper; most work fully, but some bodies show a warning or skip the battery-health readout.

We don't list a BP-81 battery yet. They are being added from our retailers' feeds; this page fills in by itself.

Matching charger

A second charger, or a dual charger, means you can charge the spare while you shoot. Most current bodies also charge in-camera over USB-C.
