Three-pack NP-FW50 replacement

This set supplies three lithium-ion NP-FW50 cells rated at 7.2 V and 1650 mAh each. They are built for owners of compatible Sony mirrorless and NEX cameras who want spare power for long shoots. The pack covers models from the Alpha 7 series, Alpha 6000 series, RX10 series and a wide range of NEX bodies.

Built-in protection circuits

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL 1642 and CE requirements. The batteries slot directly into the camera or into Sony BC-VW1 and BC-TRW chargers, and they also fit the VG-C1EM and VG-C2EM vertical grips. No extra adapters or firmware steps are needed for daily use.

Stable output and heat control

The lithium-ion chemistry delivers steady voltage through the discharge cycle while the protection circuitry limits temperature rise during continuous shooting or video recording. Normal operation stays within the cell’s thermal design, so the camera’s own cooling handles any warmth without audible fan noise from the battery itself. Power draw matches the original Sony specification for reliable run time.

Questions about this item

What voltage does the 7.2 V NP-FW50 battery deliver to the camera?

Each cell supplies a nominal 7.2 V, matching the original Sony NP-FW50 specification for compatible Alpha and NEX bodies.

What physical space do the three 3*2*3 Inch batteries occupy in a bag or grip?

Each pack measures 3 by 2 by 3 inches, so the trio fits in a standard battery pouch or Sony VG-C1EM/VG-C2EM grip.

How are the batteries installed, and what step do users often miss?

Slide each battery into the camera or charger until the latch clicks; the common mistake is stopping before the lock engages.
