Two-Pack Li-Ion Replacement

This two-pack supplies 7.4 V lithium-ion cells rated at 2300 mAh and 17 Wh each. They replace Sony NP-FM50 and NP-FM55H batteries in a long list of Handycam and Cyber-shot models. Video creators who need spare power for extended shoots can swap cells without hunting for a charger.

Low Heat Stable Output

Lithium-ion chemistry keeps the pack cool during continuous recording and the built-in protection circuit guards against over-charge, over-discharge and over-heating. Normal use draws only the current the camcorder requests so the camera’s own thermal design stays in charge.

Upgrade From Worn Originals

Owners of aging NP-FM30 NP-FM50 or NP-FM55H packs that no longer hold a full charge gain longer run time per session. The jump is worth it when a single battery cannot cover an event and carrying a second fresh cell removes the need to pause for recharging.

Highlights

  • Two batteries included for continuous power swapping

Questions about this item

How do I install the Kastar NP-FM50 battery in my Sony DCR-PC104 camcorder?

Slide the battery into the compartment until the latch clicks; the step users miss is confirming the 7.4V label faces outward so the contacts align with the camcorder terminals.

What maintenance will these Li-Ion 2300mAh packs need over time?

Store at roughly half charge in a cool, dry place; recharge every few months during long storage to keep the protection circuit active and prevent deep discharge.

Which limit appears first during continuous recording with the 17 Wh capacity?

The 2300mAh rating governs runtime; sustained high-drain recording will deplete the pack before thermal protection activates.
