The Tilta EN-EL15C rechargeable battery offers a 2400mAh capacity and a USB-C port for direct charging, making it a contemporary alternative to Nikon’s own EN-EL15 series batteries. It is compatible with a wide range of Nikon DSLRs and mirrorless cameras, including the Z8, Zf, Z7II, Z6II, Z6III, Z7, Z6, Z5, D850, D780, D810, D750, D610, D500, D7500, and D7200. This review focuses on real-world performance and practical considerations for photographers and videographers.
In everyday use, the USB-C input is the standout feature. Instead of relying on a dedicated battery charger, you can plug a USB-C cable directly into the battery to top it off. This is particularly useful when traveling or working in the field, as it reduces the number of chargers you need to carry. You can charge the battery from a power bank, laptop, or wall adapter, which adds flexibility. The battery itself feels solid, with a green casing that distinguishes it from Nikon’s original black batteries. The capacity is rated at 2400mAh, which is slightly higher than Nikon’s EN-EL15c (2280mAh) and EN-EL15b (1900mAh). In practice, this translates to a modest increase in runtime, but the difference is noticeable during long shoots. For example, with a Nikon Z6II, you can expect roughly 350-400 shots per charge under mixed conditions, depending on settings and usage patterns.
Key functional features include the USB-C port, which supports both charging and power delivery. The battery also includes standard safety protections against overcharge, short circuit, and temperature extremes. It is compatible with Nikon’s in-camera charging feature on newer models like the Z8 and Zf, allowing you to charge the battery while it’s inside the camera via USB-C. However, it’s worth noting that the battery does not include a separate charger, so if you prefer to charge multiple batteries simultaneously, you’ll need to buy a third-party charger or use the camera’s USB port one at a time.
One limitation is that the battery’s USB-C port is not as robust as a dedicated charger connection. The port is located on the side of the battery, and the cover can feel a bit flimsy. Over time, repeated plugging and unplugging may wear down the port, although this is true for most USB-C devices. Additionally, the battery’s performance in cold weather is slightly inferior to Nikon’s original. In sub-zero temperatures, the Tilta battery’s voltage drops faster, leading to shorter runtime. This is a common trade-off with third-party batteries, and it’s something to consider if you frequently shoot in freezing conditions.
Compared to generic third-party batteries that lack USB-C charging, the Tilta offers a clear advantage in convenience. Many budget alternatives require a separate charger and offer lower capacity or inconsistent performance. Nikon’s own EN-EL15c is more reliable in terms of build quality and cold-weather performance, but it costs significantly more. The Tilta sits in a middle ground: it’s more affordable than OEM but offers modern charging features that many third-party batteries lack. It is not as durable as the original, but for most users, the trade-off is acceptable.
This battery is suitable for photographers and videographers who want a cost-effective backup battery with the convenience of USB-C charging. It works well for travel, event photography, and everyday use where you have access to USB power sources. It is less suitable for professionals who demand maximum reliability in extreme conditions, or for those who prefer to charge multiple batteries at once without using the camera. If you shoot in very cold climates or rely on heavy continuous shooting, investing in Nikon’s original battery might be a better choice.
Overall, the Tilta EN-EL15C is a practical third-party option that addresses a common pain point—charging flexibility. It is not flawless, but it delivers solid performance for its price point. As with any third-party battery, it is wise to test it thoroughly before relying on it for critical work.
