Compare the Nikon EN-EL15c and EN-EL18d batteries to find the right power source for your camera. Understand compatibility, capacity, and trade-offs.
Quick answer
Choose the Nikon EN-EL15c for DSLRs and mirrorless cameras like the Z6 and Z7 series; pick the EN-EL18d exclusively for the Nikon Z9, which requires its higher capacity and different shape.
Key differences in design and compatibility
The Nikon EN-EL15c and EN-EL18d batteries look and function very differently. The EN-EL15c is a compact, rectangular battery used across many Nikon DSLRs (e.g., D810, D850) and mirrorless cameras (Z5, Z6 II, Z7 II). The EN-EL18d is larger, with a distinct shape and higher capacity, designed specifically for the Nikon Z9 and older professional DSLRs like the D5 and D6. They are not interchangeable: you cannot use an EN-EL15c in a Z9, and an EN-EL18d will not fit in cameras that accept EN-EL15c batteries.
Capacity is another major difference. The EN-EL18d offers significantly more power, necessary for the Z9's high-speed continuous shooting and video recording. The EN-EL15c provides a good balance of size and runtime for everyday shooting. If you own multiple Nikon cameras, consider whether you need to share batteries across bodies—the EN-EL15c is more versatile across models.
Price and value considerations
The EN-EL15c is more affordable, currently listed at USD 42.25 (down from USD 65.00), making it an economical choice for users who need spare batteries for compatible cameras. The EN-EL18d is priced higher at USD 147.26 (down from USD 199.00), reflecting its larger capacity and specialized design for the flagship Z9. For Z9 owners, the higher cost is justified by the need for extended shooting sessions without swapping batteries. For non-Z9 users, the EN-EL18d offers no benefit and is simply incompatible.
Trade-offs at a glance
- Compatibility: EN-EL15c fits many Nikon DSLRs and mirrorless cameras (except Z9). EN-EL18d fits only Z9 and older pro DSLRs (D5, D6).
- Capacity and runtime: EN-EL18d offers much higher capacity for extended shooting. EN-EL15c provides a good balance for general use.
- Price: EN-EL15c is significantly cheaper (USD 42.25 vs USD 147.26). The EN-EL18d costs more but is required for the Z9. Buy the EN-EL15c for multi-camera use; buy the EN-EL18d only if you own a Z9.
