Detailed overview: Sony NP-FW50 battery for Alpha A6000, A6400, A7
The NP-FW50 has been Sony's go-to mirrorless battery for over a decade, and it remains the factory cell in a large share of the APS-C Alpha lineup still in daily use. Rated at 7.2V and 1020 mAh, it uses Sony's InfoLITHIUM technology to report an exact charge percentage and remaining shooting time, not a rough estimate.
Coverage runs across the Alpha A6000, A6100, A6300, A6400, A6500 and A5100, the full-frame A7, A7 II, A7R, A7R II, A7S and A7S II, the RX10 II through RX10 IV, and the ZV-E10. Check the exact body before buying, since not every Sony mirrorless takes this cell.
Going with the genuine Sony battery avoids the two most common complaints with off-brand cells: a camera that refuses to recognize the battery, and a charge readout that cannot be trusted. Built-in protection against overcharge and overheating adds a further margin of safety. A second or third NP-FW50 in the bag is cheap insurance against a dead battery mid-shoot, whether on a wedding, a hike or a full day of travel photography.

Our tester's review: Yoni Marchal-Laporte
The NP-FW50 equipped the majority of Sony mirrorless cameras for years, and it still keeps its promise today. Its real capacity comes close to 95% of its rated 1020mAh, a solid result that puts it ahead of several compatible rivals tested under the same conditions. As a genuine Sony battery, it's recognized without reservation by every compatible body: precise display of the remaining percentage, no warning message, no crippled function. Its compatibility spans a wide range, from APS-C mirrorless bodies to the early full-frame models, as well as the RX10 expert compacts. One point deserves attention: this format gave way to the NP-FZ100 on every Sony body released from 2017 onward, and the two are not interchangeable, and Sony publishes no official cycle-count figure for this reference. For anyone who already owns a compatible body, the official NP-FW50 remains the safest option for a spare or a replacement.
