Three-pack NP-FW50 lithium-ion batteries

This three-pack supplies three Kastar NP-FW50 lithium-ion cells rated at 7.2 V, 1650 mAh and 11.8 Wh each. They are built as direct replacements for the Sony NP-FW50 and W-series batteries used in a wide range of Alpha, NEX, Cyber-shot RX10 and ZV-E10 cameras as well as compatible Sony chargers and vertical grips. The pack is intended for photographers and video creators who want spare cells ready for extended shoots.

Who these suit and who they do not

The set suits owners of the listed Sony models who need multiple spares for all-day stills or video work and who value the built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits. Users whose cameras require a different battery form factor or voltage, or who need a charger included in the box, should look at other options.

Capacity per cell: 1650 mAh at 7.2 V

Each cell delivers 1650 mAh at 7.2 V for 11.8 Wh of energy, which is the single figure that determines how long the battery can power a compatible camera before recharging. The three-pack multiplies that runtime without changing the per-cell specification.

Questions about this item

How many charge cycles can the NP-FW50 cells sustain before capacity drops noticeably?

The lithium-ion cells meet UL1642 and CE safety standards and include built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits.

What is the first limit reached when the batteries run continuously in a Sony Alpha 7 II?

Each pack delivers 1650 mAh at 7.2 V for 11.8 Wh total energy, so runtime ends when that capacity is exhausted.

How much heat or noise do three NP-FW50 packs produce during all-day shooting?

Lithium-ion chemistry generates no audible noise and minimal heat; the built-in protection circuit guards against over-heating during extended use.
