Two-pack NP-FW50 replacement batteries

This Kastar two-pack supplies a pair of 7.2 V lithium-ion cells rated at 1650 mAh and 11.8 Wh each. They are built as direct replacements for the Sony NP-FW50 battery used across a wide range of Alpha mirrorless, NEX, SLT and Cyber-shot cameras.

Check camera model and charger compatibility

Before ordering, confirm that your camera appears in the supported list covering models such as the a6000, a6100, a6300, a6400, a6500, a7 series, ZV-E10 and RX10 series. Also verify you own a compatible charger such as the Sony BC-VW1 or BC-TRW, because these cells require that specific charging interface.

Thermals noise and power draw in normal use

Lithium-ion chemistry runs silently with no moving parts, so the pack adds no audible noise during shooting. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating, keeping cell temperature stable under typical photographic loads. The 11.8 Wh capacity delivers extended run-time per charge cycle.

Questions about this item

Does the pack include a charger or do I need to buy one separately?

The box contains two NP-FW50 lithium-ion batteries only. A compatible charger such as the Sony BC-VW1 or BC-TRW must be purchased separately.

Why does the listing show both 1650 mAh and 11.8 Wh and which figure should I use to compare run time?

Both numbers describe the same cell: 1650 mAh at 7.2 V equals 11.8 Wh. Use the watt-hour rating to compare run time across different voltages.

How many shots can I expect from one 11.8 Wh battery in my Sony a6000?

A fully charged 11.8 Wh cell typically delivers 300 to 400 frames on an a6000 with the LCD on, depending on review habits and lens stabilisation.
