4-Pack NP-FW50 Li-Ion batteries for Sony cameras

This pack contains four Kastar NP-FW50 lithium-ion batteries rated at 7.2 V and 1650 mAh each. They replace the Sony NP-FW50 pack and work with a wide range of Alpha, NEX, Cyber-shot RX10 and ZV-E10 bodies as well as VG-C1EM and VG-C2EM grips. Photographers who need several spares for a full day of shooting will find the quantity convenient.

Simple drop-in replacement with protected cells

Each cell slides into the camera or compatible Sony BC-VW1 and BC-TRW chargers exactly like the original battery. Built-in circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating, meeting UL1642 and CE requirements. The only common issue is forgetting to charge all four packs before a long session, so rotate them through the charger the night before.

11.8 Wh per cell gives extended runtime

A single 11.8 Wh battery comfortably powers a mirrorless body through several hundred stills or long video clips, and four packs multiply that headroom for multi-day trips without mains access. Very high continuous video recording or cold-weather use will drain capacity faster, at which point the spare cells keep the camera running while the depleted ones recharge.

Questions about this item

How can I confirm the Kastar NP-FW50 batteries are working correctly after inserting them into my Sony camera?

The camera should power on immediately and display a full charge icon; each pack delivers 7.2 V and 1650 mAh, so shooting time should match the original Sony NP-FW50 rating.

What comes in the box and do I need to buy a charger separately?

The package contains four NP-FW50 lithium-ion batteries only; a compatible charger such as the Sony BC-VW1 or BC-TRW must be purchased separately if you do not already own one.

Which version of the Kastar NP-FW50 should I choose for my Sony a6400?

This single 4-pack version (part BA-4B-FW50-F) is the only option listed and fits the a6400 directly; no other capacities or configurations are offered.
