Four-pack Li-ion replacement batteries

This Kastar four-pack supplies 7.4 V, 2300 mAh lithium-ion cells that replace Sony NP-FM50 and NP-FM55H packs. Each unit stores 17 Wh and fits the original battery compartment without modification. The pack suits owners of compatible Handycam and Cyber-shot models who need several spares for long shoots.

Suits multi-camera owners and all-day events

Videographers running several compatible camcorders or a single camera through a full day benefit from four ready cells. Users whose gear requires a different voltage, chemistry or form factor should look at other options. Buyers needing only one replacement battery may prefer a single-unit purchase.

7.4 V 2300 mAh lithium-ion chemistry

The 7.4 V nominal voltage and 2300 mAh capacity determine whether the cell matches the camera's power requirements. Verify that your device lists NP-FM50 or NP-FM55H among its approved batteries before ordering.

Questions about this item

Will the 3 by 2 by 3 inch batteries fit the NP-FM50 compartment in my DCR-TRV14?

Yes, each battery matches the NP-FM50 form factor and is listed as compatible with the DCR-TRV14.

How do I install the four Li-Ion packs, and what step do users often miss?

Slide each pack into the camera or BC-VM50 charger until the latch clicks; the common mistake is not pressing far enough to engage the lock.

When should I replace the 2300mAh cells after repeated charge cycles?

Replace them when run time drops noticeably or the pack no longer holds a full charge after a normal cycle.
