Four-Pack Li-Ion Replacements for Sony NP-FW50

This four-pack supplies 7.2 V lithium-ion cells rated at 1 650 mAh and 11.8 Wh each. They are built as direct replacements for the Sony NP-FW50 and W-Series batteries and work with the original Sony BC-VW1 and BC-TRW chargers.

Suits owners of listed Sony mirrorless, NEX.

Photographers using the compatible Sony Alpha, NEX, SLT, Cyber-shot RX10 series, ZV-E10 or VG-C1EM and VG-C2EM grips can run all-day shoots with four spare cells. Buyers whose cameras require a different battery form factor or voltage should look elsewhere.

Each cell delivers 1 650 mAh at 7.2 V

The 1 650 mAh capacity at 7.2 V is the single figure that determines how many frames or minutes of video you can capture per charge. Match this rating to your camera's original specification to confirm suitability.

Questions about this item

Will these NP-FW50 batteries fit inside my Sony Alpha 6000 or NEX-6 body?

Yes, the NP-FW50 form factor matches the battery compartment of every listed Alpha and NEX model, so they slide in and latch without modification.

Do I need to charge the pack before first use, or can I put them straight into the camera?

Insert a battery into your Sony BC-VW1 or BC-TRW charger until the indicator shows full; the built-in protection circuit prevents over-charge, but cells ship at storage voltage and should be topped up first.

How many charge cycles can I expect before the 1650 mAh capacity drops noticeably?

The lithium-ion cells meet UL 1642 and CE standards and include over-charge, over-discharge, over-voltage, over-current and over-heating protection, which together extend cycle life well beyond unprotected alternatives.
