Sony NP-FZ100 Battery (NP-FZ100, 16.4 Wh)

Sony's proprietary battery lineup spans multiple form factors developed for different generations of cameras and accessories. The NP-FZ100 is the standard high-capacity pack used across the full-frame Alpha line from the a9 forward, including the a7 III, a7R IV, a7S III, a1, FX3, and FX30 bodies. The smaller NP-FW50 served earlier Alpha and NEX-series cameras. On the professional video side, the NP-F series — NP-F550, NP-F750, NP-F970 — dating from Handycam-era camcorders, remains widely used both as an OEM pack for older video equipment and as a de facto standard for third-party monitors, LED lights, and wireless transmission gear. Sony's BP-U series, including the BP-U70, BP-U90, and BP-U100, powers the professional XDCAM and Cinema Line camcorders such as the FX9 and PXW-FX9.

Sony's battery strategy reflects the company's broad product portfolio: each major camera generation typically introduces a new high-capacity pack matched to its power demands, while older form factors persist due to backward compatibility within the accessory ecosystem. USB Power Delivery support in newer Alpha bodies adds an alternative powering path for studio and tethered work. The NP-F format's near-universal adoption across third-party video accessories has effectively made it an industry standard for camera-adjacent power requirements.
