Four-Pack Li-Ion Kit for Sony Handycam

This Kastar bundle supplies four NP-FM50 lithium-ion batteries and a matching AC wall charger. Each cell delivers 7.4 volts and 2300 milliampere-hours, rated at 17 watt-hours. The kit targets owners of compatible Sony Digital8, Handycam and Cyber-shot models who need spare power for long shoots.

Replaces ageing NP-FM30 or NP-FM55H cells

Swapping depleted original packs for these fresh Li-Ion units restores full run-time without changing chargers. The upgrade is worthwhile when existing batteries no longer hold a charge through a typical recording session or when a multi-camera day demands more spares than a single stock pack provides.

Charger maintains steady 8.4-volt output

The wall adapter accepts 100 to 240 volts AC and supplies a constant 600 milliampere DC current. Red and green LEDs show charging and full-charge states, while the foldable flat plug keeps the unit compact during transport. Thermal regulation prevents current taper during extended top-ups.

Questions about this item

Will the foldable flat plug fit a standard UK wall socket?

The charger uses a foldable flat pin designed for North American AC outlets; a travel adapter is required for UK sockets.

How do I insert the NP-FM50 batteries so the red LED lights during charging?

Align the battery contacts with the charger slots and press down until the red LED illuminates; the light turns green when the 2300 mAh cells reach full charge.

When should I replace the four Li-Ion packs after repeated charge cycles?

Plan replacement when run-time drops noticeably below the rated 17 Wh capacity or the green LED appears much sooner than the usual charge period.
