Two-pack NP-FW50D batteries for Sony cameras

This set supplies two Kastar NP-FW50D lithium-ion cells rated at 7.2 V and 1650 mAh each, delivering 11.8 Wh per battery. They are built as direct replacements for the Sony NP-FW50 and W Series packs used across a wide range of Alpha, NEX and Cyber-shot bodies.

Suits owners of listed Sony mirrorless.

Photographers using any of the listed Sony ILCE, NEX, SLT or RX10 cameras can swap these cells in without modification. The pack also works with Sony BC-VW1 and BC-TRW chargers and the VG-C1EM grip. Users of cameras that require a different battery form factor or voltage should look at other options.

Check your camera model and charger compatibility

Verify that your specific Sony model appears in the supplied compatibility list before ordering. Ensure you have a BC-VW1, BC-TRW or USB-C 5 V 2 A source for charging, as the cells feature a built-in USB-C port with red and green LED status indicators.
