4-Pack Li-Ion Camera Battery Replacement

This four-battery set replaces Sony NP-FM50 and NP-FM55H cells for compatible Handycam and Cyber-shot models. Each unit delivers 7.4 volts and 2300 milliampere-hours for extended recording time. The pack suits owners of listed Sony camcorders and digital cameras who need multiple spare power sources.

Simple Slot-In Installation With Built-In Protection

Batteries insert directly into the camera battery compartment or listed Sony chargers such as the BC-VM50. No tools or firmware steps are required. The integrated circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. Buyers whose camera uses a different battery form factor or voltage cannot use this pack.

2300mAh Capacity Decides Run Time

The 2300 milliampere-hour rating determines how long a single battery powers your device before recharging. Match this figure to your original battery specification to confirm compatibility. Cameras requiring a higher or lower capacity cell will not achieve the expected recording duration with this pack.

Questions about this item

How can I confirm the 7.4V 2300mAh batteries are working after inserting them into my Sony DCR-TRV950?

The camera powers on and records video without the low-battery warning appearing; the charge indicator shows full bars and run time matches the 17 Wh rating.

What comes in the 4-pack and do I need a separate charger for the NP-FM50 cells?

The box contains four lithium-ion batteries; a compatible Sony BC-VM50 or BC-VM10 charger is required and not included.

Should I choose the NP-FM50 or NP-FM55H version for my Sony HDR-HC1 camcorder?

Both model numbers refer to the same 7.4V 2300mAh cell in this pack, so either designation works with the HDR-HC1.
