Will the EN-EL15a Rechargeable Li-ion Battery work with the Nikon Z6III?
Yes. Nikon EN-EL15a works where Nikon EN-EL15c (and EN-EL15b / EN-EL15a) is expected.
Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ Nikon EN-EL15a works where Nikon EN-EL15c (and EN-EL15b / EN-EL15a) is expected.
Good to know
- Nikon lists EN-EL15c for the Z8, Z6III and Z f; EN-EL15b and EN-EL15a also work but give fewer shots per charge.
- The original EN-EL15 (no letter) isn't listed for these bodies; use a lettered pack.
- Only EN-EL15c and EN-EL15b can be charged in-camera over USB; EN-EL15a cannot.
