Kastar NP-FW50 1650mAh 11.8Wh battery

The Kastar NP-FW50 is a lithium-ion replacement battery rated at 7.2V, 1650mAh and 11.8Wh. It fits a wide range of Sony Alpha, NEX, SLT, Cyber-shot RX10 and ZV-E10 cameras plus VG-C1EM and VG-C2EM grips. Built-in protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating. The cell meets UL1642 and CE safety standards.

Best for Sony shooters needing a spare

Owners of the listed Sony models who want a cost-effective spare or replacement will benefit from the higher capacity and safety circuits. It works with Sony BC-VW1 and BC-TRW chargers. Photographers using cameras that require a different battery form factor or voltage should look at something else, as this pack only fits the NP-FW50 footprint.

Capacity and runtime headroom

At 1650mAh and 11.8Wh the pack delivers noticeably longer run time than lower-capacity alternatives, supporting extended stills sessions or video recording on compatible bodies. Heavy continuous video use with power-hungry models such as the RX10 IV or A7R II will eventually drain the cell, so carrying a second pack is advisable for all-day shoots.
